Abstract

A propeller is a collection of blades that transmit power by converting rotational motion into thrust. This happens due to the difference in pressure generated between the front and rear surfaces of the blade in the form of an airfoil, and the fluid flow velocity at the rear is lower than the front so that it will produce a forward thrust. The purpose of this study was to determine the results of the manufacturing and testing process for hybrid composite propellers reinforced with unidirectional fiberglass and woven roving. Then the results of the manufacture and testing of the propeller will be compared with the nylon propeller from the factory. The propeller manufacture is carried out using the hand lay-up method using lycal 1011 resin with a geometry of 9 × 6 and for testing the propeller using the Turnigy D3536/6 1000kv engine assembled on a digital scale. Where when the engine is turned on the propeller will press down so that it can be seen on the digital scale how much the thrust value is generated. The results showed that after printing the propeller was made thicker than the size of the nylon propeller which was used as a mold reference. At the time of testing, the thrust generated by the hybrid composite propeller reinforced with unidirectional fiberglass and woven roving at high throttle was greater than that of the nylon propeller of 8.124 N
