On the use of a steerable main landing gear for crosswind landing assistance
CEAS Aeronautical Journal, 2014 Several crosswind-related incidents show that landing under heavy crosswind conditions can be challenging for pilots and may pose a threat to aviation or at least lead to higher pilot workload and/or irregularities in operations. For transport aircraft the common approach technique for crosswind landings is the so-called crabbed approach with wings ...

Failure analysis of aircraft main landing gear cylinder support
Engineering Failure Analysis, 2021 Abstract The main concern in aircraft structures is flight safety. One of the constraints to consider when designing safe aircraft parts is weight. The design of the landing gear structures is difficult because it must ensure flight safety without adding excessive weight. During takeoff, the main landing gear of a cargo plane did not retract.

Aerodynamic Measurements of the 777 Main Landing Gear Model
12th AIAA/CEAS Aeroacoustics Conference (27th AIAA Aeroacoustics Conference), 2006*† ‡ § . Aerodynamic measurements were taken over two models (13% and 26%) of the 777 high fidelity isolated main landing gear in the 6- by 6-foot Virginia Tech Stability Wind Tunnel (VT-SWT) at a free-stream Mach number of 0.16. Digital Particle Image Velocimetry measurements discussed in this paper are acquired at four locations over the 13% model of

Main Landing Gear Operation powered by Multifunctional High-Lift PCUs
2021For conventional aircraft, the high-lift and main landing gear systems are hydraulic/electric consumers with high power demands. The paper shows how the supply systems of these can be combined to save system weight and cost for future more electric aircraft.

Effects of Freeplay on Aircraft Main Landing Gear Stability
AIAA Atmospheric Flight Mechanics Conference, 2012A study is made into the occurrence of shimmy oscillations in a dual-wheel main landing gear system. Nonlinear equations of motion are developed for the system and various nonlinear effects are considered including gyroscopic coupling, nonlinear tyre properties, geometric nonlinearities and fluid damping.

Cracking in an Aircraft Main Landing Gear Sliding Strut
1993Abstract Examination of several fighter aircraft main landing gear legs revealed unusual cracking in the hard chromium plating that covered the sliding section of the inner strut. The cracking was associated with cracks in the 35 NCD 16 steel beneath the plating.

C-5A Main Landing Gear Bogie Pitching Control
Journal of Aircraft, 1970The C-5A six-wheel main landing gear bogie, as the result of a high flotation requirement, poses a problem for designing a wheel braking torque compensating mechanism which stabilizes bogie pitching during braking. For ground operation, the bogie is also required to pitch ±12° with respect to the shock strut. During retraction of the main gear, however,

Failure of a Main Landing Gear on a Light Airplane
2019Abstract Initial investigation showed that a landing gear failure was the result of a hard landing with no evidence of contributory factors. The objective of reexamination was to determine whether there was any evidence of metallurgical failure.
