The present research is due to study the performance of engine-propeller cells to be used in the design of a Micro Air Vehicle (MAV). Design conditions: weigh less than 200gr, maximum size 30cm, to fly a distance of 200m, and be able to carry a camera and chemical sensors. One of the goals of the study is to use commercial parts (engines and propellers) in order to reduce manufacturing cost. An experimental methodology was used to measure the followings variables for the engine-propeller cell: Thrust (T), velocity (RPM), cylinder head temperature (CHT), wind incident velocity (VD), aerodynamic drag (D), torque (Q) and velocity profile behind every propeller. Results: aerodynamic Drag Coefficient of the propeller-engine cell (engine off), for each propeller. Dynamic Thrust: test with engine and tunnel on, at different RPM and different tunnel flow velocity.
