Abstract

An auxiliary propeller folding mechanism of a model airplane glider comprises a steering engine and an auxiliary propeller, wherein the steering engine comprises an oscillating arm, the auxiliary propeller is connected with an output shaft of a power element, the power element is connected with a machine body through a parallel four-connection-bar mechanism, the steering engine is fixed in the machine body, and the oscillating arm is connected with any one connection bar in the parallel four-connection-bar mechanism. A position sensor is arranged at the tail end of the stroke of the power element, the first connection bar or the second connection bar and is connected with the control end of a controller or the steering engine through a signal line. The steering engine drives the parallel four-connection-bar mechanism, and the auxiliary propeller and the power element can contract in the machine body or protrude out of the machine body. In the powerless gliding flight process, the auxiliary propeller and the power element contract in the machine body, and accordingly the aerodynamic performance of the machine body can be remarkably improved, resistance can be reduced and the glider hang time can be prolonged.

Description

Technical field: [0001] The invention relates to the field of machinery, in particular to a flyable model airplane, in particular to a glider in a model airplane, in particular to an auxiliary propeller folding mechanism of a model airplane glider. Background technique: [0002] In the prior art, the model airplane glider is not towed by the front machine during the lift-off process, and needs to rely on its own power to reach the gliding height. Therefore, the model airplane gliders in the prior art are all provided with power elements and auxiliary propellers, and start the auxiliary propellers during take-off to help the model airplane gliders reach the glide height or enter the updraft. After the model airplane gliders reach the glide height or enter the updraft, Turn off the power element to realize unpowered gliding flight. However, during unpowered gliding flight, the auxiliary propeller is subjected to air resistance, which affects gliding and reduces the airborne t...
