A multidisciplinary teaching method in the aerospace engineering systems fiel...Altair
The purpose of this paper is to present the effectiveness of a new teaching methods through all the graduation process for engineering students, ranging from the BSc to the MSc level.
Two hundred undergraduate students in aerospace engineering at the Politecnico di Torino were involved in this teaching process. The paper presents the organization of the learning process through the different academic years.
The process implicates theoretical lectures, computer laboratories, and experimental workbench, and shows how different multidisciplinary concepts and models, useful for the aerospace systems design, can be presented and then worked again in the next courses. In particular, an example concerning the flight control system is presented underlining how the models can be introduced at the third year, with the support of some engineering tools, and then reprised and developed in more details at the fifth year, with an effective and quick heritage of knowledge.

We all have good and bad thoughts from time to time and situation to situation. We are bombarded daily with spiraling thoughts(both negative and positive) creating all-consuming feel , making us difficult to manage with associated suffering. Good thoughts are like our Mob Signal (Positive thought) amidst noise(negative thought) in the atmosphere. Negative thoughts like noise outweigh positive thoughts. These thoughts often create unwanted confusion, trouble, stress and frustration in our mind as well as chaos in our physical world. Negative thoughts are also known as “distorted thinking”.

3. Aerospace is the human effort in science, engineering and business to fly in the
atmosphere of Earth (AERONAUTICS) and surrounding space (ASTRONAUTICS).
Aerospace organizations/industry conduct activities such as aerospace research, design,
development, manufacturing, assembly, integration, test and operations, or maintain
aircraft systems and/or spacecraft. The Aerospace activity is very diverse, with a
multitude of commercial, industrial and military applications.
Aerospace is not the same as Airspace, which is the physical air space directly above a
location on the ground. The beginning of space and the ending of the air is considered as
100 km above the ground according to the physical explanation that the air pressure is
too low and recognized by authorities.
WHAT IS AEROSPACE ?
5. THE AEROSPACE TECHNOLOGY ACCUMULATES ALMOST THE ENTIRETY OF THE MOST ADVANCED
SCIENTIFIC, TECHNICAL AND MANAGERIAL HUMAN KNOWLEDGE.
MOST OF THE AEROSPACE TECHNOLOGY IS USED IN ALL OTHER HUMAN ACTIVITIES AND SOCIAL
PROCESSES IN FIELDS SUCH AS MEDICINE, INFORMATICS, CONSTRUCTION, TRANSPORTATION,
FOOD PROCESSING, INDUSTRIAL GOODS/EQUIPMENT, MARINE , COMMUNICATIONS ETC.

27. WHAT IS MANAGEMENT?
MAN – AGIRE = Act Upon and Through MenMANAGEMENT
In other words MANAGEMENT is the Art and Science of
Getting Tasks Done on Time Through Combined Resources.
28. WHAT IS AEROSPACE PROJECT (OR PROGRAM) MANAGEMENT ?
AEROSPACE PROJECT MANAMENT (PM) is the business and administrative planning,
organizing, directing, coordinating, controlling, and approving actions required to
accomplish the overall Aerospace System Acquisition Project objectives within its
Phased Life-Cycle.
The primary challenge of Project Management is to achieve all of the project goals and constraints. This
information is usually described in a User or Project Requirements Specification, which is created at the
beginning of the Project. The primary constraints are scope, time, quality and budget. The secondary —
and more ambitious — challenge is to optimize the allocation of necessary inputs and integrate them to
meet pre-defined objectives.
31. MAIN FUNCTIONS OF PROJECT MANAGEMENT
1) LEAD To inspire the participants to accomplish the goals and objectives at a level that meets or
exceeds expectations. It is the only function of project management that occurs simultaneously with the
other functions. Whether defining, planning, organizing, or controlling, the project manager uses
Leadership to execute the project efficiently and effectively.
2) DEFINE To determine the overall vision, goals, objectives, scope, responsibilities, and deliverables of
a project. A common way to capture this information is with a Statement Of Work (SOW). This is a
document that delineates the above information and is signed by all interested parties.
3) PLAN To determine the steps needed to execute a project, assign who will perform them, and
identify their start and completion dates. Planning entails activities such as constructing a Work
Breakdown Structure (WBS) and a Schedule for starting and completing of the project.
31
32. MAIN FUNCTIONS OF PROJECT MANAGEMENT-continue
4) Organize To orchestrate the resources cost-effectively so as to execute the plan. Organizing
involves activities such as forming a team in the form of a Project Management Office (PMO) ,
allocating resources, calculating costs, assessing risk, preparing project documentation, and ensuring
good communications.
5) Control To assess how well a project meets its goals and objectives. Controlling involves
collecting and assessing status reports, managing changes to baselines, and responding to
circumstances that can negatively impact the project participants.
6) Close To conclude a project efficiently and effectively. Closing a project involves compiling
statistics, releasing people, and preparing the lessons learned document.

WBS- An Example of Work Breakdown Structure (WBS)-AW101 Helicopter Integrated System
37. WBS USE-The First Task to Do When Starting a Project
The WBS is a Project Management Tool. It provides a
framework for specifying the technical aspects of the
project by defining the project in terms of hierarchically-
related, product-oriented elements and the work
processes required for each element's completion. Each
element of the WBS provides logical summary points for
assessing technical accomplishments, and for measuring
cost and schedule performance.
1) technical management
2) work identification and assignment
3) schedule management
4) cost management
5) performance measurement
38. THE PROJECT SCHEDULE
Provides a framework of time-phased and coordinated activities which
represent the plan for completing the project within established constraints.
Used:
To integrate all elements of a project as a function of time and flow
As a communication tool across the project team
As a basis for assessing project status
For project management control
Key inputs:
The work breakdown structure (WBS)
External constraints (such as imposed System Delivery for Flight date)
Required milestones (such as technical reviews)
Major deliverables
Imposed funding profiles
39. Project Scheduling Approaches
Gantt Chart: A graphic portrayal of a project which shows the activities to be completed and the time
to complete represented by horizontal lines drawn in proportion to the duration of the activity.
Milestone Chart: A graphic portrayal of a project that shows the events to be completed on a
timeline.
Network Scheduling
• Critical Path Method (CPM): A graphical technique that aids understanding of the dependency of
events in a project and the time required to complete them.
• Program Evaluation and Review Technique (PERT): A technique based on constructing a network
model of integrated activities and events. Difference from CPM: uses statistical theory and
probability to make a determination of duration time for each task and the likelihood of an event
being on schedule.
40. Gantt & Milestone Charts (Pros and Cons)
ADVANTAGES
1) Simple to prepare and update,
2) Information portrayed in easily understood format,
3) Relatively inexpensive to prepare using software
tools,
4) Relate activities and calendar dates,
5) Easy to roll up information into summary form,
6) Useful first step for preparation of more complex
type schedules
7) Reliable estimates can be developed when the work
is repetitive and when the product is easy to
measure quantitatively.
DISADVANTAGES
1) Difficult to use for detailed schedule analysis
2) Do not show the effects of late or early activity
starts,
3) Do not represent dependencies among activities
as well as other scheduling methods
4) Do not reflect the uncertainty in the planned
activity duration or event date
5) Only as reliable as the estimates on which they
are based; looking at the chart doesn’t indicate
which estimates are the most reliable
6) Do not allow quick or easy exploration of the
consequences of alternative actions.
41. CARGO TRANSPORT RPAS R&D PROJECT MASTER SCHEDULE (GANTT CHART )-EXAMPLE
Gantt and milestone charts are best
used for displaying the planned
activities and events of a project and
the progress in meeting them. This
makes them very useful for
presenting schedule and program
status information in a concise
simple format at such things as
program or activity reviews.
Because of its simplicity and ease of
interpretation, it is a particularly
good tool for communicating to
higher management when
information must be presented
quickly and efficiently.
42. Network Schedule (Example)
In this example, the lines represent project activities A through H;
the nodes represent the events associated with the beginning and
end of the activities. The network shows the following constraints
among the activities: activity A must be completed before
activities B, C, or D can begin; B must be completed before E can
begin; F cannot begin until D is completed; G cannot begin until C
and E are done, and H cannot begin until F and G are completed.
In addition to showing this type of sequencing constraints,
network schedules can also show the time and resources planned
for each activity and thus provide managers with a mechanism to
monitor and control the project.
H
Network schedule data consists of:
Activities
Dependencies between activities
Milestones that occur as a result of
one or more activities
Duration of each activity

44. Example: Critical Path and Float
Critical Path is the sequence of activities that will take the longest to accomplish. Any delay on this
path will delay the project.
Example: 14 days,
Activities that are not on the critical path have a certain amount of time that they can be delayed until
they, too are on the critical path. This time is called float (or slack).
Example, Path 1: 9 days => 5 days of float +
Example, Path 2: 13 days => 1 day of float +

Three estimates are required:
• Most Likely, m
• Optimistic, a
• Pessimistic, b

te = a+4m+b

ma b
Beta Probability Distribution
Using PERT, it is possible to determine an expected time for completion of a project and the likelihood (probability) that
this expected completion time will be met. Projects best suited for PERT are one-of-a-kind complex programs that
involve new technology or processes and research and development.
46. 46
Network Schedules
ADVANTAGES
1) Provide graphical portrayal of project activities and
relationships/constraints
2) Force communications among team members in
identifying activities
3) Organize what would otherwise be confusing
material, making it easier for managers to make
tradeoffs and develop alternative plans
4) Give managers more control over activities/events
and schedules
5) Facilitate “what if” exercises
6) Provide the basis for Gantt and milestone chart
information
DISADVANTAGES
1) Network construction can be difficult and time
consuming.
2) Only as sound as the activity time and resource
estimates.
3) Sometimes difficult to portray graphically—too many
lines, nodes and intersections.
4) Not particularly good for conveying information in
briefings/reviews.
5) Complex networks, once sketched out on a large wall
chart, tend to become the focus of management
attention when, in fact, a manager should be paying
attention to factors not on the chart, such as
management/ labor relations.
47. Schedule Preparation
A five-step process for schedule preparation that is commonly used in project
management includes:
1. Activity definition - what has to be accomplished?
2. Activity sequencing - what has to occur first, second…?
3. Activity duration estimation - how long does activity take?
4. Schedule development - what are realistic start & finish dates?
5. Schedule control - how to manage changes & track performance?
Risk is inherent in all programs, and scheduling is one element of risk. Uncertainty introduced in
estimating the duration of each activity causes most schedule risk. Project managers must assess
the likelihood of failing to meet schedule plans and the impact of that failure. Probabilistic
techniques have proven to be very useful in conducting these assessments.
49. Additional topics if you are interested in adding to the lecture:
Earned Value Management (EVM)
A tool for measuring and assessing project performance through the integration of technical scope with
schedule and cost objectives during the execution of the project. EVM provides quantification of
technical progress, enabling management to gain insight into project status and project completion costs
and schedules.

54. What is Systems Engineering?
Systems Engineering is a robust approach to the design, creation, and operation of
systems. The approach consists of:
• identification and quantification of system goals
• creation of alternative system design concepts
• performance of design trades
• selection and implementation of the best design
• verification that the design is properly built and integrated, and
• assessment of how well the system meets the goals
This approach is iterative, with several increases in the resolution of the system baselines (which contain
requirements, design details, verification plans and cost and performance estimates).
55. The System Engineering Process is given by the mapping:
SE : N F
𝑮∗𝑾 𝑺
WS where N and F are the Environmental and Resource Inputs respectively and WSis
the entire Process. The Objective Function for the whole system GWS is expressed by GWS = g [ G (SCHEDULE
CONTROL; G ( OPERATIONAL SYSTEM); G (SUPPORT SYSTEM). An Optimal Value for an Systems Engineering
Problem is given by the Functional:
G*WS = minMSE { 𝒕𝟎
𝒕𝟏
𝒈𝐬c (X𝐬c, MSE, N) dt} + max MOS, MSS { E|L (XOS, XSS, MOS, MSS, N, U) (tf-tc)}
Where gSC is the Performance Function for Schedule Control (SC), xsc represents the trajectory of SC, MSE are
the Model Outcomes from SE. The second term in the above functional relation represents the measure of the
System Cost-Effectiveness.

System Engineering
Management (SEM)
System Engineering is a standardized, disciplined management process for development of system solutions that provides
a constant approach to system development in an environment of change and uncertainty. System Engineering
Management ensures that the correct technical tasks get done during development through planning, tracking, and
coordinating. Responsibilities of Systems Engineering Managers include:
Development of a total system design solution that balances
cost, schedule, performance, and risk,
Development and tracking of technical information needed for
decision making,
Verification that technical solutions satisfy customer
requirements,
Development of a system that can be produced economically
and supported throughout the life cycle,
Development and monitoring of internal and external interface
compatibility of the system and subsystems using an open
systems approach,
Establishment of baselines and configuration control, and
Proper focus and structure for system and major sub-system
level design
58. Systems Engineering Management is accomplished
by integrating three major activities:
Development phasing that controls the design
process and provides baselines that coordinate
design efforts;
A systems engineering process that provides a
structure for solving design problems and tracking
requirements flow through the design effort; and
Life cycle integration that involves customers in the
design process and ensures that the system
developed is viable throughout its life.

62. To Be a Systems Engineer You
Must Be a Systems Thinker …
See the forest and not only the trees
View from different perspectives
Look for interdependencies
Understand different models
Think long term
“Go wide” in thinking about cause and effect relationships
Think about potential benefits (opportunities) as well as about unintended consequences (risks)
Focus on problem solving, not finding blame
63. PROJECT TEAMWORK
A major difference between university studies and the work world: Transition from Individual Work
Performance to Team Work Performance.
Systems Engineering Relies on Teamwork
A multidisciplinary team is system engineer’s most powerful tool.
Often called Integrated Product Team (IPT) or Integrated Product Development Team (IPDT).
Team led by systems engineer, with all significant technical disciplines represented.
Reasons / Value of this approach:
1) No one individual has all the required knowledge.
2) Diverse team interaction encourages ingenuity and creativity.
3) Reduces engineering design time.
4) Enables fewer problems in transition from engineering to manufacturing to operations.
5) Identifies and resolves technical subsystem conflicts early.
64. Today’s challenge: “Team of teams”
• Team members are dispersed geographically
• Different culture basis
• Different process approaches
• Your team’s performance depends on a sub-team or supplier’s performance
Goal: Creating a culture of collaboration
• Explicitly reward collaboration traits
• Honesty, integrity, sharing, receptivity, consistency, respect
• Build trust
• Individual involvement in planning, creating, strategizing, structuring

68. 1. Establish evaluation criteria
2. Establish relative importance of evaluation criteria
3. Develop alternative concepts that meet objectives and top-level requirements
4. Evaluate alternatives relative to the established evaluation criteria
5. The alternative that best satisfies the evaluation criteria represents the tentative concept choice
6. Tentative concept choice is evaluated in more detail to identify any unforeseen drawbacks
7. In light of the information gained from the more detailed study, the decision is finalized or the
decision maker returns to Step 3
Basic Steps in the Decision Making Process
70. The Performance Function G of a Controlled Integrated System is expressed in the following three (3) cases of
interest:
1) CONTINUOUS CONTROL
G 𝒕 = 𝒎𝒂𝒙 𝒎(𝒕) 𝒕𝟏
𝒕𝒇
𝒈 𝒙, 𝒏, 𝒚, 𝒎, 𝒕 𝒅𝒕
2) DISCRETE CONTROL (e.g. policy iteration, dynamic programming, game theory)
G(r)= 𝒎𝒂𝒙 𝒎(𝒓){Gmax (r-1) + g(r) (x,n,u,m,r)}
3) OPTIMAL DESIGN (e.g. Multivariable search in automation and control engineering)
G = 𝒎𝒂𝒙 𝒎{E(x,n,u,m,t) | L (x,m,t) } generally E(.) is for System Effectiveness and L(.) is for the
System Cost
In Systems Engineering, the Entire System is characterized by four (4) types of Functional Systems:
1) Operational System, 2) Maintenance System, 3) Transport System, and 4) Procurement System.
THE PERFORMANCE FUNCTION OF A CONTROLLED INTEGRATED SYSTEM
72. What Is a System Architecture?
A system Architecture is the link between needs analysis, project scoping and functional analysis and the first
descriptions of the system structure.
Creating a system architecture is the beginning of
the system design process and establishes the link
between requirements and design. The typical
architecture development sequence is:
1. Establish initial system requirements by needs
analysis, project scoping, and the development
of the concept of operations (Con Ops).
2. Define the external boundaries, constraints,
scope, context, environment and assumptions.
3. Develop candidate system architectures as part
of an iterative process using these initial
requirements.
4. For each architecture, compare the benefits,
costs, risks and the requirements that drive their
salient features and consider modifying (with
stakeholder involvement) their Con Ops, system
performance and even their system functions to
improve the solution-problem proposition.
73. Architecture vs. Design
A system architecture creates the conceptual structure within which subsequent system design occurs.
Developing a system architecture and developing a system design are systems engineering functions
that support system synthesis, but they have different uses.
System architecture is used:
• To establish the framework for subsequent system design
• To support make-buy decisions
• To discriminate between alternative solutions
• To ‘discover’ the true requirements or the ‘true’ priorities
System design is used:
• To develop system components that meet functional and performance requirements and constraints
• To build the system
• To understand the system-wide ripple effects of configuration changes

78. Some Words about Requirements
What is a Requirement?
Requirement is a Statement of some THINGS you
want or need
OR
A characteristic of some THINGS you want or need
A requirement is also…
• A Contractually Binding Statement
• Documentation of Need Domains
• The Means We Use to Communicate in a Project
Mutual
Understanding
Requirements Come:
From the Future User/Customer of the System
From Project Stakeholders/Sponsor(s)
From Organizational Standards and Government Regulations
By Virtue of Project Life Cycle Needs, Trade-offs and Necessary Evolutions
79. Functional - Requirements which define
what an item must do.
Performance - Requirements which
define and quantify how well an item
must accomplish a particular function.
Constraints - Requirements that capture
operational, environmental, safety or
regulatory constraints.
Verification - Requirements capture how
confidence will be established that the
system will perform in its intended
environment.

82. Requirements are decomposed via three methods, namely flow-down, allocation and derivation.
1. Requirement flow-down is a direct transfer since a subsystem provides the capability.
2. Allocation is a quantitative apportionment from a higher level to a lower level and for which the unit of measure
remains the same. Examples include mass, power, or pointing.
3. Requirement derivation is an apportionment that depends on the specific implementation.
Requirements are Decomposed Following the Functional Architecture

84. Functional analysis is the systematic process
of identifying, describing, and relating the
functions a system must perform in order to
be successful. It does not address how these
functions will be performed.
In the early phases of the project life cycle,
functional analysis deals with:
• The top-level functions that need to be
performed by the system;
• Where theses functions need to be
performed;
• How often they need to be performed; and
• Under what operational concept and
environmental conditions.
Later in these early phases, functional
analysis proceeds to lower levels of the
system decomposition to define the system
functional design and interfaces.

86. System synthesis, also known as system design,
translates the system functional architecture into
a physical architecture. It creates a ‘how’ for
every ‘what’ and ‘how well’.
For each functional subsystem, alternative
physical solutions are considered, trade studies
are performed and a preferred solution picked.
System synthesis is an iterative process - namely,
as different physical architectures are considered
functional or performance allocation may be
changed to create a ‘balanced’ solution.
A ‘balanced’ solution means that there is
consideration of the overall system risk, cost,
technical maturity and robustness for each
combination of subsystems.
The products of system synthesis include a
physical architecture baseline (the ‘design-to’
baseline) and the subsystem trade study results.
