Abstract:
This paper is devoted to presentation of impact absorbers equations applied on aircraft landing gears.The landing gear shock absorber is an integral component of an aircraft’s landing gear.
The role of the shock absorber is to absorb and dissipate energy upon impact, such that the forces imposed on the aircraft’s frame are tolerable. These accelerations must be acceptable not only to structural components, but also to everything contained within the aircraft (passengers, cargo, weapons, avionics etc).Designing a shock absorber is an iterative process, as each aircraft is individual and the shock absorber must be optimized to reduce size and weight, whilst maintaining the desired performance.
The following set of equations offer a general starting point for this design process. Often the design must be altered from the initial conception to find an optimum balance between performance, weight and size.
INTRODUCTION
Designing a shock absorber is an iterative process, as each aircraft is individual and the shock absorber must be optimized to reduce size and weight, whilst maintaining the desired performance. The following set of equations offer a general starting point for this design process. Often the design must be altered from the initial conception to find an optimum balance between performance, weight and size. These equations have been derived from a basic energy analysis of an aircraft during landing.
Cessna 177RG
The Cessna 177RG is a general aviation aircraft that is primarily operated by private individuals and organizations.
The aircraft may carry 4 persons (including 1 crew), utilizes a high wing configuration, and is powered by a single engine. The maximum takeoff weight of the Cessna 177RG is 1100 kg.
