Primary and secondary aircraft with wing tips connected in parallel

Abstract

The invention relates to a primary and secondary aircraft with wing tips connected in parallel. The primary and secondary aircraft is a high-aspect-ratio subsonic aircraft composed of a primary aircraft (1) and two secondary aircrafts (2) through a connecting mechanism (3), wherein the two secondary aircrafts (2) are symmetrically mounted at two sides of the primary aircraft (1); the primary aircraft (1) is of a high-aspect-ratio subsonic layout form; the two secondary aircrafts (2) are respectively positioned at the left and right wing tips of the primary aircraft (1) and are of a straight wing layout form; and the connecting mechanism (3) is positioned between a primary wing tip (4) and secondary wing tips (5) and is connected with the primary aircraft (1) and the secondary aircraft (2)by adopting a slide rail or a link mechanism. The secondary aircrafts (2) can independently complete corresponding flight missions by virtue of self-power, thereby being favorable for reducing the damage risk of the primary aircraft (1), reducing the using cost and being favorable for improving the using cost-effectiveness ratio of the unmanned aerial vehicle.

Description

technical field [0001] The invention belongs to the technical field of unmanned aerial vehicle design, and relates to a parent-child aircraft composed of a large unmanned aerial vehicle and two small unmanned aerial vehicles connected in parallel through wing tips. Background technique [0002] For the combination of conventional aircraft, the sub-aircraft is mounted on the belly, fuselage or wing of the parent aircraft through the suspension device. After the sub-aircraft is mounted on the parent aircraft, the flight performance of the combined aircraft cannot be improved while meeting the purpose of use. , the slave aircraft will only increase the flight resistance of the parent aircraft, reduce the lift-to-drag ratio of the aircraft, and affect the flight performance of the aircraft. [0003] The conventional design of the combined aircraft of the mother aircraft uses the aircraft of the mother aircraft as a flight carrier. After reaching the predetermined target area, th...

AI Technical Summary

Problems solved by technology

The sub-machine aircraft is small, with low design and manufacturing costs, and can adapt to the needs of high-risk areas. It is a consumable product; the parent aircraft is generally a large aircraft with complex systems and high design and manufacturing costs. It has great advantages in terms of performance, but due to cost reasons, it is not conducive to performing more dangerous tasks. Once damaged, it will bring greater losses to the user; the combination of child and mother aircraft is to combine the advantages and disadvantages of the child aircraft and the parent aircraft. developed
