Tandem double-seat general airplane

Abstract

The invention discloses a tandem double-seat general airplane. The airplane comprises a drop-shaped airplane body, a pair of V-shaped vertical fins, a turbine propeller engine, a thrust propeller andan upper single wing arranged at the upper part of the airplane body, wherein the V-shaped vertical fins, the turbine propeller engine and the thrust propeller are arranged at the rear part of the airplane body; a front seat and a rear seat are arranged in the airplane body, and the front seat and the rear seat correspond to a front glass cabin cover which is opened upwards and a side cabin door which is opened towards the side face respectively. The airplane body adopts a drop-shaped section, aerodynamic drag reduction of the airplane body is well achieved, meanwhile, an engine is arranged atthe rear, and the influence of propeller slip flow on the aerodynamic performance of the airplane is reduced. The upper single wing design is adopted, the downward view of passengers is improved, andthe airplane is more suitable for sightseeing of the passengers. The functions of horizontal tails and the vertical fins are combined through the V-shaped vertical fin design, and the structural weight is reduced. A buoy is arranged on the lower portion of the airplane body, an undercarriage can be retracted and released, water landing can be achieved in emergency, and the safety of the passengers is improved. Meanwhile, overall parachutes are arranged on the back of the airplane body, so that the safety of the airplane and the passengers in emergency is further guaranteed.

Description

technical field [0001] The invention relates to the technical field of aircraft manufacturing, in particular to a tandem two-seater general-purpose aircraft. Background technique [0002] At present, the existing tandem two-seat general-purpose aircraft mainly include three types of aircraft, such as the Chinese Junior Education 6, the Czech Shark Aircraft, and the Austrian DART-450. Their common characteristics are the conventional low-wing, low-level tail layout, and lack of good downward direction. The field of view, and all use pull propellers, and the engine is arranged at the nose. The propeller slipstream affects the overall aerodynamic performance of the aircraft and increases the induced drag of the aircraft. Chinese patent CN205418063U discloses "a flying car with a tandem two-seater layout", which has the following problems: 1. The layout of the double vertical tail + high horizontal tail is adopted, resulting in a large structural weight and low maneuverability o...

Chinese patent CN205418063U discloses "a flying car with a tandem two-seater layout", which has the following problems: 1. The layout of the double vertical tail + high horizontal tail is adopted, resulting in a large structural weight and low maneuverability of the aircraft; The horizontal tail is in the slipstream area of ​​the propeller, the aerodynamic surface efficiency is low, and it is easy to cause structural acoustic fatigue of the tail, and the service life of the product is low; 3. The tires of the car cannot be placed in the fuselage compartment, resulting in large aerodynamic resistance and affecting the fuel economy of the aircraft , to further reduce the range of the aircraft
