Abstract

The utility model relates to a fan Engine for a model airplane, composed of a fan, a guiding machine, an electromotor, a guiding cone, and a housing. A fan engine is arranged in the inner of an airplane body of the model airplane, because of the effect of the guiding machine and the guiding cone, air flow of the fan flows along an axle direction, so that the flight of the model airplane imitates that of a jet flight.

Description

Fan Engine for model airplane

The utility model relates to the used Duct-Burning Turbofan of a kind of model airplane aircraft.

General engine model is heavier owing to weight, and the air discharge capacity is little, and has noise and the bigger problem of vibration after starting, and therefore influences the flight of model plane.

The purpose of this utility model is at above-mentioned the deficiencies in the prior art, and a kind of model plane Duct-Burning Turbofan is provided.

The purpose of this utility model can reach by following measure: the model plane Duct-Burning Turbofan is made up of fan, guider, motor, flow deflecting cone and housing, guider and housing are the integrated through injection molding profiled member, its core is a hollow cylinder housing, in this hollow cylinder housing motor is housed, the shaft extension of motor is equipped with fan to front end and on axle; Flow deflecting cone is equipped with in above-mentioned hollow cylinder housing rear end.

The drawing of accompanying drawing is described as follows:

Fig. 1 is model plane jet airplane model and the device schematic representation at the model plane Duct-Burning Turbofan of fuselage interior.

Fig. 2 is the front view of the utility model model plane Duct-Burning Turbofan.

Fig. 3 is the side view (part is cut open) of the utility model model plane Duct-Burning Turbofan.

The utility model is described further below in conjunction with drawings and Examples: see also Fig. 1, model plane Duct-Burning Turbofan device of the present utility model is in the fuselage interior of model plane jet airplane.

See also Fig. 2 and Fig. 3, model plane Duct-Burning Turbofan of the present utility model is made up of fan 1, guider 2, motor 3, flow deflecting cone 4 and housing 5, wherein: guider 2 is injected and molded in one with housing 5, its core is the hollow cylinder housing of taking turns paddy shape, the inner motor 3 of installing, so that fan 1 is installed, guiding awl 4 is equipped with at the rear portion to the shaft extension of motor 3 to front end.

Motor 3 provides electric energy by chargeable cell, when motor 3 rotates, the fan that drives the front rotates, the design of fan is discharged after making big air flow, thereby the generation forward thrust, and the effect by guider 2 and flow deflecting cone 4 flows exhaust preferably vertically, and unlikely generation flow-disturbing and vortex, not only improved efficient but also reduced noise and vibration, made aeromodelling airplane can simulate jet airplane and take off and fly.This is a unique distinction of the present utility model.

In sum, model plane Duct-Burning Turbofan of the present utility model has the advantage that the air discharge capacity is big, in light weight, volume is little, simultaneously owing to adopted guider 2 and flow deflecting cone 4 that air-flow is flowed vertically in fan, thereby improved efficient and reduced noise and vibration, real design and the structure that belongs to novelty.This motor can also be used on the aeromodelling airplane of other patterns.

Claims

1, a kind of model plane Duct-Burning Turbofan, comprise fan, guider, motor, flow deflecting cone and housing, it is characterized in that: described guider and housing are the integrated through injection molding profiled member, its core is a hollow cylinder housing, device one motor in this hollow cylinder housing, the shaft extension of this motor is equipped with a fan to front end and on axle; The guiding awl is equipped with in above-mentioned hollow cylinder housing rear end.
