Design and Analysis of Under Carriage Uplock Lever Mechanism of an Aircraft

In aviation, the undercarriage or landing gear is the structure (usually wheels) that supports an aircraft on the ground and allows it to taxi. The landing gear being one of the components of the aircraft experiencing very high loads, very high strength materials are made use of in its construction, in order to keep its size and weight to a minimum. This paper deals with the study and design of the uplocks lever, which is an important part of the landing gear in aircraft in an existing aircrafts and record the various design parameters and determining the optimal design. Model of the uplock lever is generated in CATIA V5 and calculation of loads acting at various points is done in NASTRAN and minimum required dimensions of different components in the assembly and their design with drafting tools is done.
