Problems solved by technology
Among these wings, the single straight wing and double straight wing have good low speed performance but poor high speed performance
Swept wings perform well at high speeds but poorly at low speeds
In order to make the aircraft take into account both high-speed and low-speed performance, people invented variable-wing aircraft, but the wing structure of this aircraft is complicated, the weight increases, and the strength performance decreases
When the aircraft is in flight, the entire weight of the fuselage is applied to the intersection of the wings and the fuselage, which has little effect on small aircraft, while large and medium-sized aircraft need to increase the fuselage and wings in order to meet the strength requirements The application of high-strength materials, thereby greatly increasing the weight of the aircraft

Embodiment 1
[0013] Embodiment 1: with reference to Fig. 1~shown in Fig. 3, a kind of biplane comprises by body, wing, rudder, engine, and wherein, described wing is by front wing (2) and rear wing (4) Composition, the described front wing (2) is installed on the bottom surface of the front part of the body (1), and the described rear wing (4) is installed on the top of the rear part of the body (1).
Embodiment 2
[0014] Embodiment 2: Referring to Fig. 4, the described wing is composed of a front wing (2) and a rear wing (4), which has the same structure as that of Embodiment 1, except that the body (1) Install two or more side by side.

The invention is concerned with the soft-land system for airplane, consists of the airplane, the lifting load-bearing vehicle of the airplane and the runway, it is: the airplane is without undercarriage, which the airplane is landing on the water surface when it is landing, the lifting load-bearing vehicle carries the airplane to finish the run operation; the lifting load-bearing vehicle carries the airplane to fly on the normal runway when the airplane is flying-off. The invention is without the undercarriage for the airplane that contains the passengers increasing from 200 to 300, improves the flying efficiency.
Description
Technical field: [0001] The invention belongs to aircraft, in particular to a biplane. Background technique: [0002] At present, the wings used by aircraft include single straight wing, double straight wing, swept wing, variable wing, and compound wing. Some countries are still studying forward swept wing technology. Among these wings, the low-speed performance of the single straight wing and the double straight wing is very good, but the high-speed performance is poor. Swept wings perform well at high speeds but poorly at low speeds. In order to make the aircraft take into account high-speed and low-speed performance, people have invented variable-wing aircraft, but the wing structure of this aircraft is complicated, the weight is increased, and the strength performance is reduced. When the aircraft is in flight, the entire weight of the fuselage is applied to the intersection of the wings and the fuselage, which has little effect on small aircraft, while large and mediu...
