Ronald O'Rourke; LIBRARY OF CONGRESS WASHINGTON DC CONGRESSIONAL RESEARCH SERVICE
|
 | Some Members of Congress this year have expressed interest in the option of procuring a 10th San Antonio (LPD-17) class amphibious ship in FY2009, so as to help meet the Marine Corps goal for amphibious lift capability. The Navy's proposed FY2009 budget does not request funding for a 10th LPD-17 and instead proposes ending LPD-17 procurement with the ninth ship, which was procured in FY2008. The Navy's proposed FY2009 budget ... |

| Fixed-wing micro air vehicles (MAV) are very attractive for outdoor surveillance missions since they generally offer better payload and endurance capabilities than rotorcraft or flapping-wing vehicles of equal size. They are generally less challenging to control than helicopter in outdoor environment. However, high wing loading associated with stringent dimension constraints requires high cruise speeds for fixed-wing MAVs and it has been difficult so far to achieve good performances at low-speed ... |

| Since the start of the global war on terrorism, many operations involving U.S. forces have been supported by helicopters, to include combat operations, counterinsurgency operations, security operations, disaster relief, and humanitarian assistance operations. But in many cases, rotary wing aircraft have not been well suited to the mission. In fact, helicopter-related losses are among the leading causes of fatalities in operations in Afghanistan and Iraq. In consideration of these facts, ... |

| In order to avoid adverse consequences due to failures, it is desirable to have an advanced failure detection and isolation (FDI) system that detects and identifies anomalies early to minimize the damage, and that can remedy as many failures as possible. In complex systems, fault diagnosis is typically accomplished using a hierarchical approach. In our proposed autonomous unmanned vehicle (UAV) system, fault diagnosis, isolation and recovery (FDIR) is accomplished by ... |

| In combat casualty and civilian environments, an unmet need exists for a stethoscope that can hear heart and especially breathing sounds while inside helicopters, fixed-wing aircraft, or ambulances where noise levels preclude auscultation with standard stethoscopes. Without this capability, patients can suffer from unidentified collapsed lungs or loss of intubation integrity with the threat of loss of life.

| In order to enhance flight performance, numerous Naval and joint DoD development programs feature head-supported devices (HSD) for fixed and rotary wing aircraft, e.g. night vision goggles and displays. However, wearing these systems during long duration operations or while exposed to repeated shock, impact, ejection, and crash increases the risk of spinal injury. Factors that affect injury tolerance include the additional weight, which typically pitches the head forward, age, gender, ... |

| Unmanned aerial vehicles (UAVs) have become increasingly popular for many applications, including search and rescue, surveillance, and electronic warfare, but almost all UAVs are controlled remotely by humans. Methods of control must be developed before UAVs can become truly autonomous.

| As military systems have become more complex, testing has become more time consuming and costly. A number of efficiencies have been proposed and implemented, such as increasing use of modeling and simulation and combining developmental and operational testing. How have these approaches worked in practice? And do traditional metrics for estimating the cost of testing still apply? This study addressed these issues by examining system-level testing for selected fixed-wing aircraft, ... |

| Ice accretion on the wings of fixed-wing aircraft and on the rotors of rotor-wing aircraft can have disastrous results. The ice that forms on a wing structure especially along the leading edge modifies the wing aerodynamics resulting in decreased lift. In the extreme this can lead to stall and loss of control of the aircraft and potentially a crash. Ice building up elsewhere on the wing rotor or airframe can ... |

| Icing is among aviation's most serious weather hazards because it renders aircraft unflyable before flight and severely reduces aircraft performance within flight. Army aviation is vulnerable to icing, which occurs most frequently at lower altitudes, and which generally has the greatest impact upon small fixed-wing aircraft and helicopters that fly slowly and low. Icing causes mission delays during ground deicing of aircraft and mission cancellations and abortions because of forecast ... |
