Abstract
Long-term exposure to vibration adversely affects mental and physical condition of the pilot and increases body fatigue. This paper presents the results of tests dealing with the measurements of vibrations at the seat and cabin floor of the flight instructor of the piston engine propeller aircraft and other engine and flight, parameters. Two tests were conducted, one with a rubber absorber built in under the pilot seat and the other test without the absorber. The research is based on an analysis of magnitude of the vibration accelerations, at the harmonics of the engine running speed, in three flight regimes. The applied rubber absorber, with certain physical properties and mechanical characteristics, has provided the desired vibration damping on the seat in vertical direction of Z axis, in all flight profiles on Propeller Rotation Frequency and its several harmonics.
