Design and Analysis of UAV Test Bench for Engine/Motor Characterization

Abstract

A thrust test bench is an instrument which can measure the Thrust, Rpm, Power, Torque, Temperature Explicitly etc. This is composed of the test bench architecture attached to the motor or the engine through the rotating shaft. An absorber being attached to the engine means nothing but an extra component which drives the energy of the motor, that is a propeller if assumed. The main objective here is to design a Test Bench which can maximum hold the weight of UAV Engines or motors within 15kgs and to conduct Structural Finite Element Analysis on different parts of the test bench to determine the stress behaviour. The parameters which the test bench can measure are Thrust, Velocity, Rotational Speed, Torque, Cylinder Head Temperature, Exhaust Temperature etc. This is achieved by using certain sensors introduced with a DAQ system for precise and accurate measurements of the parameters.
