The Results Of The T-45 Main Landing Gear Uplock Investigation And The Effect That Organization Structure Had On Them, Christina Marie Stack
Masters Theses
The T-45, a military jet trainer aircraft for the Navy, recently experienced two cases of an uncommanded main landing gear extension during high airspeed and high g conditions. These events resulted in an investigation to understand the cause. The initial response to the mishaps was to limit the fleet to lower airspeeds since both mishaps occurred at high speeds. This limitation was not extensively restrictive for fleet operations; however, it was limiting for acceptance flights and functional check flights of aircraft. During the investigations, two different mechanical problems were discovered in the main landing gear uplock mechanism. This mechanism is …

Use Of Commercial Off The Shelf Gps Technology To Solve Guidance Problems With The Improved Tactical Air Launched Decoy (Itald), Scott Kenneth Toppel
Masters Theses
As the capabilities of threat surface-to-air missile systems increased, the US Navy looked to improve upon the performance of the Tactical Air Launched Decoy (TALD), an air launched glider vehicle with switchblade wings designed to resemble attacking aircraft to confuse and saturate enemy air defenses. In the early 1990’s the contractor proposed the Improved Tactical Air Launched Decoy (ITALD), a turbo jet powered air-launched vehicle which tripled the existing range and added a radar altimeter to simulate low level attacks.
In 1998, after several design iterations, the Naval Air Warfare Center at Point Mugu tested the ITALD for suitability in …
H-53e Super Stallion/Sea Dragon Auxiliary Power Plant Power Survey, Patrick Joseph Twomey
H-53e Super Stallion/Sea Dragon Auxiliary Power Plant Power Survey, Patrick Joseph Twomey
Masters Theses
This research has provided possible explanations to failures experienced in the P-7-2 Auxiliary Power Plant reduction gearbox as installed on the CH-53E Super Stallion and MH-53E Sea Dragon helicopters. Ground testing with the rotors static was conducted during two separate phases from March 1995 to December 1995. Reduction gearbox loading was measured, resulting in the identification of several detrimental over and transient loads. Loading reduction techniques are investigated, discussed, and/or evaluated for U.S. Navy and U.S. Marine Corps fleet introduction viability.
