Description

Water-air cross-medium amphibious aircraft with anti-sileman wings Technical Field The invention relates to the technical field of aircrafts, in particular to an anti-Emerman wing water-air-span medium amphibious aircraft. Background The water-air cross-medium amphibious aircraft is special equipment capable of taking both air flight and underwater diving into consideration, and has wide application prospects in the fields of marine resource exploration, water area search and rescue, sea defense inspection and the like. The conventional fixed wing span medium aircraft mostly adopts a conventional rectangular wing layout design, and has the following technical defects that the conventional fixed wing span medium aircraft is difficult to reconcile in a complex working environment of water-air span medium. Firstly, the volume of the water discharged is overlarge, and the load capacity of the whole machine is insufficient. In order to meet the buoyancy balance requirement of underwater submarine navigation, the traditional rectangular wing span medium aircraft mostly adopts a thick wing type design, the thickness of the wing is usually 0.1-0.14 times of the chord length, and the excessive drainage volume directly leads to the weight exceeding of the whole aircraft, so that the effective load capacity is greatly reduced, even the wing load exceeds the safety range, and the flight safety is influenced. The lift margin is insufficient in the low Reynolds number environment, and the maneuvering performance and the safety are poor. The traditional rectangular wing medium-crossing aircraft has large whole weight, the attack angle required by air cruising is close to the critical stall attack angle in a low-speed low-Reynolds number flight environment, the stall risk of the aircraft is high, the maneuvering adjustment space is small, and complex working conditions are difficult to deal with. Third, the cross-medium conversion efficiency is low, the energy consumption is high, and the response is slow. The density difference between water and air is nearly 800 times, so that the contradiction of irreconcilable wing loads exists in the traditional design, namely, the air flight needs smaller wing loads to reduce resistance and promote endurance, the underwater diving needs larger wing loads to balance buoyancy and promote anti-flow interference capability, and the contradiction directly leads to long time consumption and high energy consumption in the water-air medium conversion process of the aircraft, so that the continuous operation efficiency of the aircraft is severely restricted.
