Model plane

Abstract

The invention discloses a model plane which comprises a model plane body. A model rear plane body is mounted at the horizontal position of the tail of the model plane body, model fixed tail wings arevertically mounted on two sides of the model rear plane body, model main wings are horizontally and fixedly mounted on two sides of the middle of the model plane body, upper shells are embedded into the middles of the model main wings, a first motor steering engine is embedded into one side of each upper shell, a first crank is connected with one side of each first motor steering engine through apin, a second connecting rod is connected at the tail end of each first crank, a first connecting rod is movably connected at the tail end of each second connecting rod, a second crank is movably connected at the tail end of each first connecting rod, and a motor connector is arranged at the tail end of each second crank. According to the model plane, the falling off probability of an engine can be reduced, flight safety is improved, the plane is provided with a crank mechanism, a power output direction is changed, utilization of engine efficiency is improved, and power wastage is reduced.

Description

Technical field [0001] The invention relates to the field of airplane models, in particular to a model airplane. Background technique [0002] An airplane refers to a power device with one or more engines to generate forward thrust or pulling force. The fixed wing of the fuselage generates lift, which is heavier than air flying in the atmosphere. The airplane is the most common type of fixed wing. Aircraft can be divided into jet planes and propeller planes according to the types of engines they use. A model plane is a movable or static model that is specially and innovatively manufactured by installing existing aircraft. Model planes are generally the same as manned planes. Similarly, it is mainly composed of six parts: wing, tail, fuselage, landing gear, engine and control system. The engine is the most core part of the model aircraft. The existing aircraft models are low in cost and low in design accuracy. When the engine is fixed, it will not adopt the all-inclusive fixation...

Problems solved by technology

[0002] Aircraft refers to a power plant with one or more engines to generate forward thrust or pull, and the fixed wings of the fuselage to generate lift. The aircraft is heavier than air and flies in the atmosphere. The aircraft is the most common type of fixed wing. Aircraft can be divided into jet planes and propeller planes according to the types of engines they use, and model planes are movable or static models that are installed with existing aircraft for special innovation. Model planes are generally the same as manned planes. Similarly, it is mainly composed of six parts: wing, empennage, fuselage, landing gear, engine and control system, and the engine is the most core part of the model aircraft. The existing aircraft models are low in cost and low in design accuracy, so When the engine is fixed, it will not use all-inclusive fixing, but only use a simple snap-fit ​​connection, but when the model aircraft does some stunts in flight, it will generate a large load inside the aircraft, and the engine itself will bear a large load. pressure, and simple fixation cannot meet the fixation under these special load conditions, which will lead to problems such as engine falling off. At the same time, most model aircraft use propellers to provide power, but the existing propellers basically use directional fixed propellers, and the engine cannot be The power of the engine is fully utilized. When taking off, the longitudinal propeller arrangement makes the power loss of the engine extremely serious.
