Fixed wing aircraft

Abstract

The invention discloses a fixed wing aircraft model. The fixed wing aircraft model comprises an aircraft body, fixed wings fixed on the two sides of the aircraft body and a front duct power unit and a back duct power unit, wherein the front duct power unit is vertically arranged in the middle of the aircraft body, air flow generated by the front duct power unit faces the lower surface of the aircraft body, the back duct power unit is connected to the tail of the aircraft body through a back duct fixing seat, and different angles are formed between the back duct power unit and the aircraft body through rotation of a back duct rotating seat around the aircraft body. According to the fixed wing aircraft model convenient for vector control over flight forms, vertical take-off and landing are achieved, level flight can be achieved through the fixed wings, a precise vector control mechanism is arranged, and the flight modes are stably and quickly switched.

Description

【Technical field】 [0001] The invention relates to an aviation model, in particular to a fixed-wing aircraft model. 【Background technique】 [0002] At present, the flight attitude adjustment of the aviation model mainly depends on the airflow pressure difference between the two sides of the wings. Usually, the methods of using the two sides of the wings to control the flight include: using the mechanical structure to change the tilt angle of the two sides of the wings or using the Vertical fans are installed on the wings to adjust the inclination angle of the wings on both sides; this method is not convenient for precise vector control of the aircraft model, and the movable wings are not strong enough. The strength has higher requirements. On the other hand, the installation of vertical fans on both sides of the wings not only increases the load of the aircraft model, but also the exposed vertical fans affect the streamline of the fuselage, which in turn affects the flight dy...

[0002] At present, the flight attitude adjustment of the aviation model mainly depends on the airflow pressure difference between the two sides of the wings. Usually, the methods of using the two sides of the wings to control the flight include: using the mechanical structure to change the tilt angle of the two sides of the wings or using the Vertical fans are installed on the wings to adjust the inclination angle of the wings on both sides; this method is not convenient for precise vector control of the aircraft model, and the movable wings are not strong enough. The strength has higher requirements. On the other hand, the installation of vertical fans on both sides of the wings not only increases the load of the aircraft model, but also the exposed vertical fans affect the streamline of the fuselage, which in turn affects the flight dynamics and the adjustment of the flight posture. The powerful power required for the vertical take-off and landing of the aircraft model needs to be equipped with more power engines, and the vertical engine is turned off during level flight, which becomes a burden on the aircraft model
