Abstract

The utility model discloses an improved airplane comprising an airplane body and wings, wherein a pair of middle wings is arranged in a position close to the rear below a main wing, and the length and width of each middle wing are both smaller than those of the main wing; and a triangular rear edge part is arranged at the rear edge of a juncture of a winglet and the main wing. By using the improved airplane, the technical problems of poor flying horizontality and smoothness, poor stability in flying at a low speed, high flying resistance and overwater taking-off resistance and the like of the traditional airplane can be solved.

Description

A kind of follow-on aircraft

Technical field

The utility model relates to a kind of aircraft, is specifically related to a kind of improvement technology to aircraft.

Background technology

The device that traditional aircraft plays control lifting power is the trailing edge flap of the movable angle adjustable of installing in wing rear portion.This wing flap is in the process of aircraft lifting and landing, increasing lift, but resistance increases in normal flight.The wing limit winglet trailing edge of traditional aircraft is concordant, and its shortcoming is in-flight and when landing of taking off, the junction of wing limit winglet and main wing can produce a rotation on eddying turbulence, aircraft is produced vibration and violent wild effect such as lifting.Therefore traditional hydroairplane exists the big problem of the resistance that takes off owing to there is not hydrofoil.

Summary of the invention

The purpose of this utility model provides a kind of follow-on aircraft, and resistance increases in the normal flight that traditional aircraft exists, low-speed operations lift is poor to solve, in-flight and technical matters such as the fugitiveness when taking off landing and water takeoff resistance be big.

In order to realize the foregoing invention purpose, the technical scheme that the utility model place is used is as follows:

A kind of follow-on aircraft comprises fuselage and wing; Position after inclined to one side below the main wing is provided with a pair of wing centre section, and the length of this wing centre section and width are all less than main wing; Establish leg-of-mutton back along portion at the trailing edge place of wing limit winglet and main wing junction.

Aforesaid a kind of follow-on aircraft, the position that suited before middle part below the fuselage is provided with a hydrofoil, and this hydrofoil is a plate of striking that is fixed under the fuselage, and this hydrofoil is used parts for taking off, and has the device of regaining in the fuselage of packing up when flight.

Advantage of the present utility model and effect: owing to be provided with wing centre section, increase lift, reduce resistance, so stationarity and the good stability of the landing of taking off, the coasting distance of the landing of taking off dwindles 50%; Owing to increased behind the triangle of wing limit winglet along portion, the stationarity of stationarity and safety, particularly low-speed operations that has therefore increased flight is better; Hydroairplane is when taking off, and hydrofoil can increase lift, is easy to take off.

Fig. 2 is the right elevation of Fig. 1.

Fig. 3 is the birds-eye view of Fig. 1.

Fig. 4 is schematic perspective view of the present utility model.

The specific embodiment

The concrete structure of follow-on aircraft described in the utility model is referring to Fig. 1,2,3,4.It comprises fuselage 1 and wing, and better for the horizontality and the stationarity that make flight, and the flight of low speed is more stable, is provided with a pair of wing centre section 4 in the position after partially below the main wing 2, and the length of this wing centre section 4 and width are all less than main wing 2.In Fig. 3 as can be seen, the below that wing centre section 4 is positioned at main wing 2 partially after, namely wing centre section 4 backs are along the rear that is positioned at edges, main wing 2 back in the vertical.

In order to eliminate eddying turbulence in the generation rotation of the junction of wing limit winglet and main wing in-flight, the utility model is established leg-of-mutton back along portion 6 at the trailing edge place of wing limit winglet 3 and main wing 2 junctions.

When as hydroairplane, in order to overcome the problem of the resistance that takes off, the position that the utility model suited before middle part below the fuselage 1, be provided with a hydrofoil 5, this hydrofoil 5 is the plates of striking that are fixed under the fuselage, and this hydrofoil is used parts for taking off, and has the device of regaining in the fuselage of packing up when flight.The position that described hydrofoil 5 arranges according to different aircrafts, is condition to be conducive to running take off, is set in different positions.

Claims

1. a follow-on aircraft comprises fuselage and wing; It is characterized in that the position after inclined to one side below the main wing is provided with a pair of wing centre section, the length of this wing centre section and width are all less than main wing; Establish leg-of-mutton back along portion at the trailing edge place of wing limit winglet and main wing junction.

2. a kind of follow-on aircraft according to claim 1, it is characterized in that, the position that before middle part below the fuselage, suits, be provided with a hydrofoil, this hydrofoil is a plate of striking that is fixed under the fuselage, and this hydrofoil is used parts for taking off, and has the device of regaining in the fuselage of packing up when flight.
