  32. 32. Fuel Cells PEM• The Department of Energy (DOE) is focusing on the PEMFC as the most likely candidate for transportation applications• High power density and a relatively low operating temperature (ranging from 60 to 80 degrees Celsius, or 140 to 176 degrees Fahrenheit).• The low operating temperature means that it doesnt take very long for the fuel cell to warm up and begin generating electricityHydrogen is channeled through flow plates to theanode on one side. Oxygen flows through plates onthe cathode side. At the anode the hydrogen splits Anode side:into ions and electrons. The membrane only allows 2H2 => 4H+ + 4e-positive ions to flow through to the cathode. The Cathode side: O2 + 4H+ + 4e- => 2H2Oelectrons must travel through a an external circuit Net reaction:to the cathode creating an electrical current. At the 2H2 + O2 => 2H2Ocathode, the electrons and positive hydrogen ionscombine with oxygen to form water which flows outof the cell. When the hydrogen and oxygen is used Used on Apollo mission andup, the fuel cell shuts down. provided drinking water 30

  35. 35. LOS Fundamentals Link Budget Analysis• Free space attenuation depends on frequency & distance• Free space attenuation (or loss) increases with frequency• The amount of free space attenuation can be computed using the following formula:• FSL = 36.6 + 20 Log (F) + 20 Log (D)• Where:• F = Frequency in MHz• D = Distance in Miles• Example: A 2.4 GHz 5 mile path• Log (2400) = 3.380211 (x20) = 67.604225• Log (5) = 0.698970 (x20) = 13.979400• Path Loss = (36.6 + 67.604225 + 13.979400) = 118.183625 dB 33

Image Compression JPEG• JPEG is a lossy compression format conceived explicitly for making photo files smaller• JPEG stands for the Joint Photographic Experts Group, a committee set up in 1986• The baseline uses an encoding scheme based on the Discrete Cosine Transform (DCT)• Compression ratios are normally 10:1 Source:www.fileformat.info 35
  38. 38. STANAG 4586• Processes, procedures, terms and conditions for common military or technical procedures or equipment between member countries• The objective of this standardization agreement is to specify and standardize elements that will be implemented in the UAS Control System The main elements that this agreement covers are: – UAS Control System (UCS) Architecture (GCS = UCS) – Data Link Interface (DLI). – Command Control Interface (CCI). – Human Control Interface (HCI)• The UCS communicates with the UAS through message sets in a Data Link Interface (DLI) through the Vehicle Specific Module (VSM)• STANAG 4586 does not regulate HW, SW, design or material solutions – UAV systems manufacturers are free to implement design of software solutions while still being able to produce interoperable units 36

  51. 51. Predator Case Study• The Predator design evolved from a DARPA program (FY84–FY90).• In January 1994, the Army awarded General Atomics Aeronautical Systems a contract to develop the Predator system.• The initial ACTD phase lasted from January 1994 to June 1996.• During the initial ACTD phase, the Army led the evaluation program, but in April 1996, the Air Force replaced the Army as the operating service for the initial ACTD aircraft (RQ-1) (the “R” designates reconnaissance role)• The Predator was designed to provide persistent intelligence, surveillance, and reconnaissance (ISR) coverage of a specified target area.• As an ISR platform, the Predator carried either an electro-optics/infrared (EO/IR) sensor package or a synthetic aperture radar (SAR) package.• In FY02, the RQ-1 migrated into MQ-1 (the“M” designates multirole) with the addition of a weapon-carrying capability. 49

  56. 56. COA Process Certificate of Authorization• In 1997 the FAA and DoD agreed upon and wrote the initial COA process• FAA amended Order 7610.4 Special Military Operations to implement the current COA process that is used by the military today.• Use and number of requests for UAS use has grown over the past 10 years• The increase has caused a backlog and slowed down the COA process• Need to examine the current process and determine how to improve• The Application for COA should be submitted at least 60 days prior• The FAA’s UAPO processes COA, determines updates or changes, either grants the request for a specified period of time, up to a year, or denies it• Granted to DoD and other public agencies operating UA in the support of: – National Defense COMPANIES WILL NOT BE APPROVED – Disaster Relief – Scientific Research – Technological Development 54

  65. 65. Human Machine Interface Sensory Isolation of Operator• One of the most prominent HMI issues is sensory isolation from operator• UAS operators receive visual information from sensors• Imagery collected is limited in terms of range and quality• UAV operators do not have access to vestibular cues such as turbulence, weather conditions, aircraft movement and gravitational forces.• Turbulence: manned aircraft detects immediate, UAS operator may only detect after noticing perturbation of the delayed video imagery• Could result in a failure to detect and if the turbulence is severe enough, this could jeopardize the safe and effective control of the vehicle• MCE operators for the 2001 GH demo rated ability to detect and diagnose abnormal conditions on the UAS via the HMI as poor 63
  66. 66. Human Machine Interface Sensory Isolation of Operator• In 2002 one of the USAF GHs returning from a mission in support of OEF crashed after departing from controlled flight• Part of the rudder mechanism failed• If the failure had occurred on a manned aircraft, sensory feedback would alert the pilot immediately, may have been time to recover• Installation of multisensory interfaces may be beneficial• Tactile feedback: vibration on the wrists, forearms, or control stick• Force feedback on the control stick• Cockpit environmental noise and spatial audio cueing• AFRL project called “multimodal immersive intelligent interface for remote operation (MIIIRO)• Provides a sense of presence but needs more investigation 64
