Vertical take-off and landing tilt lift fan unmanned aerial vehicle with compact layout

Abstract

The invention belongs to the technical field of aviation aircraft design, and discloses a vertical take-off and landing tilting lift fan unmanned aerial vehicle with compact layout, which comprises a lift body fuselage, a balancing lift fan, a right main lift fan, a left main lift fan, a right wing, a left wing, a right empennage and a left empennage. Through reasonable arrangement and combination of the lift surface and the lift device, the problem that the high-lift airfoil profile head lowering moment is large is solved through the nose lift fan, positive lift cruise trimming similar to duck-type layout is achieved, and the take-off weight is increased; the slip flow of the main lift fan is fully utilized, the slip flow lift augmentation effect is achieved, and the cruise lift is increased; under strict layout size constraints, the maximum take-off weight, cruising speed and voyage of existing equipments of the same size are far higher than those of existing equipments of the same size.

Description

technical field [0001] The invention belongs to the technical field of aviation vehicle design, relates to a vertical take-off and landing unmanned aerial vehicle, in particular to a compact layout vertical take-off and landing tilt lift fan unmanned aerial vehicle. Background technique [0002] In modern warfare, with the development of weapons and equipment and the extensive use of military high-tech technologies, the frontline battlefield environment is complex and dangerous, which puts forward higher requirements for the accuracy and timeliness of material supplies. [0003] Our army's current task of supplying front-line troops is mainly completed by land supply and air transportation. Land supply is mostly carried out by wheeled vehicles, which have high requirements on the road traffic conditions at the supply location, and the supply cycle is long and the efficiency is low, and it is easy to be intercepted and attacked by the enemy. Air transportation and supply can...

AI Technical Summary

Problems solved by technology

Land supply is mostly carried out by wheeled vehicles, which have high requirements on the road traffic conditions at the supply location, and the supply cycle is long and the efficiency is low, and it is easy to be intercepted and attacked by the enemy

Air transportation and supply can be carried out by manned fixed-wing transport aircraft and helicopters. Although it can solve the problem of supply guarantee for the front-line dispersed combat units to a certain extent, the fixed-wing transport aircraft has a large body, weak protection, and poor maneuverability. High-value military targets that the enemy's air and ground forces focus on hunting, and have high requirements for take-off and landing sites

Although the helicopter is limited by the site, its load capacity is low and its flight speed is slow, which is not conducive to the long-distance transportation of large equipment
