 | On September 24, 2009, the Department of Defense (DOD) announced its proposed strategy for conducting a new competition between Boeing and a team consisting of Northrop Grumman and the European Aeronautic Defense and Space Company (EADS, the parent company of Airbus) for a program to build 179 new KC-X aerial refueling tankers for the Air Force. The estimated total value of the 179-aircraft KC-X program is roughly $35 billion. Boeing ... |

| In the debate over future U.S. defense spending, including deliberations taking place in the current Quadrennial Defense Review (QDR), a key issue is how much emphasis to place on programs for countering improved Chinese military forces in coming years. Observers disagree on the issue, with some arguing that such programs should receive significant emphasis, others arguing that they should receive relatively little, and still others taking an intermediate position.

|
| The term Deepwater refers to a collection of more than a dozen Coast Guard acquisition programs for replacing and modernizing the service's aging fleet of deepwater-capable ships and aircraft. Until April 2007, the Coast Guard pursued these programs as a single, integrated acquisition program that was known as the Integrated Deepwater System (IDS) program or Deepwater program for short. The now-separated Deepwater acquisition programs include plans for, among other things, ... |

|
| Air transport training programs provide simulator-based upset-recovery instruction for company pilots. However, no prior research demonstrates that such training transfers to an airplane in flight. We report on an FAA-funded research experiment to evaluate upset-recovery training transfer. Two groups of participants were given simulator-based training in upset-recovery, one in a high-end centrifuge-based device, the other using Microsoft Flight Simulator running on desktop computers. A third control group received no upset-recovery ... |

| Buffet-induced vibrations can have a disastrous impact on aircraft structures. Early attempts at combating buffet vibrations included passive methods such as structural enhancements and leading edge fences. Active methods have shown greater promise, including active airflow control, control surface modulation, and active structural control using piezoelectric actuators. Surface mounted piezoelectric actuators impart directional strain reducing the negative effects associated with harmful vibration. The Block-15 F-16 ventral fin represents an aircraft ... |

|
| The United States Air Force has advanced fighter aircraft that lose the ability to operate in a large portion of their operating flight envelope when an air data system failure is experienced. These aircraft are reverted to a fixed set of standby-gains that limit their maneuverability, degrade handling qualities, and increase susceptibility to departure. The purpose of this research was to determine if three alternative methods of standby-gain-scheduling could provide ... |

| Traditionally, a deterministic simulation is used to estimate airborne cargo and passenger delivery in wartime scenarios. Deterministic models address reliability by removing the number of non-mission capable aircraft from the total possessed numbers at the very beginning of the delivery process. Only mission capable (MC) aircraft, minus any special mission withholds, are used in the model. Most important, once an aircraft is deemed to be MC, it never fails anywhere ... |

| Since the 1980s, the V-22, developed to transport combat troops, supplies, and equipment for the U.S. Marine Corps and to support other services' operations, has experienced several fatal crashes, demonstrated various deficiencies, and faced virtual cancellation--much of which it has overcome. Although until recently deployed in Iraq and regarded favorably, it has not performed the full range of missions anticipated, and how well it can do so is in question. ... |

| Recently, Gravity Gradient Instruments (GGIs) - devices which measure the spatial derivatives of gravity, have improved remarkably due to development of accelerometer technologies. Specialized GGIs are currently flown on aircraft for geological purposes in the mining industries. As such, gravity gradient data is recorded in flight and detailed gradient maps are created after post mission processing. These maps, if stored in a database onboard an aircraft and combined with a ... |

| The trade-off between false alarm and detection probability is a fundamental challenge in the automated detection of contacts in passive sonar systems. A common approach is the application of high gain processing followed by successive classification criteria. Most classification schemes (e.g., matching of signature) are complex and tailored to specific target types. By contrast, the Doppler effect is readily observed in all contacts with discrete tonals and relative velocity to ... |

| Increasingly high aircraft power demands require that the interactions between an aircraft's electrical subsystem and the engine subsystem be considered in dynamic, system-level tests. Traditionally, system-level dynamics have only been captured in completely assembled aircraft systems. Component-level or subsystem-level optimization is no longer appropriate because highly interdependent dynamics between subsystems only become apparent during system-level analysis. In an effort to mitigate program risk, enable system-level optimization, and reduce the high ... |

| The increasing need for timely information in any environment has led to the development of mobile SATCOM terminals. SATCOM terminals seeking to achieve high data-rate communications require inertial antenna pointing to within fractions of a degree. The base motion of the antenna platform complicates the pointing problem and must be accounted for in mobile SATCOM applications.

Multiple UAS platforms can be synchronized to link devices from separate UAS platforms thus proving a powerful capability for data collection, while opening up interesting opportunities in the way data is retrieved and used. A range of new sensors being investigated will be discussed with ... |

| A Geographic Corrosivity Index (GCI) has been developed previously that models the atmospheric corrosivity at RAAF bases within Australia. Geographic, wind and other climate data are used to calculate the index for each base. The correlation of the GCI with atmospheric corrosion data from a large number of overseas bases, covering a broader range of geographic features and climatic conditions than experienced in Australia, was investigated to test its wider ... |
