2. PROBLEM STATEMENT:-
● Increased Volume (capacity).
● Lack of Quality – via inconsistency of
manufacturing and increase in variability.
● High Costs.
● Dependency on hard to find labour to work in
harsh operating conditions.
● Lack of Safety Occupational health statistics
continue to illustrate that major source of
industrial accidents.
3. INTRODUCTION:-
● Aerospace industry, assemblage of manufacturing concerns
that deal with vehicular flight within and beyond Earth’s
atmosphere.
● The aerospace industry is engaged in the research,
development, and manufacture of flight vehicles, including
unpowered gliders and sailplanes ,lighter-than-air craft ,
heavier-than-air craft , missiles, space launch vehicles, and
spacecraft (manned and unmanned).
● Also included among its concerns are major flight-vehicle
subsystems such as propulsion and avionics (aviation
electronics) and key support systems necessary for the
testing, operation, and maintenance of flight vehicles.
5. FABRICATION PROCESSES AND
MATERIALS:
● Fabrication involves the manufacture of individual components that make up larger
assemblies or end products.
● This activity encompasses the working of metals and the incorporation of electrical and
electronic devices into processors, circuit boards, and subassemblies for the components of
navigation, communication, and control systems.
● In modern systems, hundreds of functions are performed by a single microchip or, in
conjunction with micro miniaturized elements, by printed circuit boards.
● Metals are cut, shaped, bored, bent, and formed by tools and machines operated manually
under the control of computers programmed to guide the necessary operations consistently
and with greater precision than can normally be provided by humans.
● The parallels for electrical and electronic fabrication are robotic tools for insertion of
components into circuit boards, wave soldering for rapid, uniform connections, and
photolithography for making circuit boards and multichip modules.
6. BUILDING OF SUBASSEMBLIES:-
● Assembly of aerospace vehicles at the prime contractor or systems
integrator begins with the accumulation of subassemblies.
● The segments are taken to the subassembly area, where teams of workers
fit them into support jigs or fixtures and join them into a unit, within which
the interior equipment is then installed.
● In similar manner, teams put together other subassemblies such as the
remaining fuselage sections, wing sections, tail sections, and engine
nacelles.
● The various subassemblies then are taken to the main assembly line, where
final integration takes place.
7. FINAL ASSEMBLY:-
● The final assembly of complete aircraft
usually requires a facility furnished with a
network of overhead rails on which ride
heavy-lift cranes capable of moving large
portions of vehicles.
● Aircraft assembly normally starts with the
joining, or mating, of fuselage
subassemblies that have been craned into a
supporting jig or fixture.
● As the vehicle is assembled, it is moved
through a succession of work stations,
acquiring additional subassemblies and
accumulating its onboard systems, ducts,
control cables, and other interior plumbing.
8. DISCUSSION:-
● Technological progress is the basis for competitiveness and advancement in
the aerospace industry.
● The industry is, as a result, a world leader in advancing science and
technology.
● Aerospace systems have a very high value per unit weight and are among the
most complex, as measured by the number of components in finished
products.
● Among the world’s largest manufacturing industries in terms of monetary
value of product output and employment, the aerospace industry is
characterized by a relatively small number of large firms and numerous
international partnerships at every level.
10. RESULT:-
● Aerospace manufacturing is a specialized and complex process but
smart manufacturing is simplifying things! For example, when it comes to
robotics, some end-of-arm-tooling effectors are IoT connected for
real-time data collection and optimization. Additionally, scanners are
being used to identify the part material and robots use this information to
select the specified bolt size and apply the appropriate level of torque for
that specific material.
● Designers and manufacturers have, and will continue, to push the
envelope on load capacities for robotic equipment and end effectors in
order to effectively handle the largest aircraft components.
11. ...
● Smart technologies and sensors allow manufacturers to collect real-time
information to determine the status of operations at any given moment –
and react and adjust operations accordingly. These smart technologies also
extend into predictive maintenance programs where companies can
monitor equipment real-time to improve responsiveness and achieve fewer
unplanned outages.
● Innovations within Artificial Intelligence (AI) continue to be implemented,
allowing automation solutions to perform increasingly complicated jobs in
shorter periods of time.
12. CONCLUSION:-
● The product line of the aerospace industry is, by necessity, broad because its
primary products—flight vehicles—require up to millions of individual parts.
● In addition, many support systems are needed to operate and maintain the
vehicles. In terms of sales, military aircraft have the largest market share,
followed by space systems and civil aircraft, with missiles still a modest
grouping.
● The industry’s customers range from private individuals to large corporations
and commercial airlines, telecommunications companies, and military and
other government agencies.
