Short take-off vertical landing aircraft

Abstract

Disclosed is a short take-off vertical landing aircraft comprising a fuselage, main engines, a vertical fin, and main wings, upper wings, end wings and canards which are arranged at both sides of thefuselage; the outer sides of the end wings are provided with extension wings; the two extension wings are provided with ailerons; the two upper wings are provided with elevators; the tail portions ofthe two end wings are provided with rudders; the lower parts of the two end wings are provided with forward direction stretching support structures, and each forward direction stretching support structure is provided with a main engine, a main engine propeller and a propeller dip angle driving device; the lower portion of each end wing is provided with a retractable main undercarriage; and the rear portion of the vertical fin is provided with a backward stretching support structure, and the backward stretching support structure is provided with an attitude-adjusting engine propeller. The shorttake-off vertical landing aircraft not only has short distance take-off and vertical landing performance, but also takes into account flight performance of high speed, long endurance and large voyage, and so on.

Description

technical field [0001] The invention belongs to the field of aircraft design, and in particular relates to an aircraft with a joint-wing canard aerodynamic layout with excellent aerodynamic performance, which can realize short-distance take-off and vertical landing. Background technique [0002] Aircraft has the characteristics of fast speed and high maneuverability, and is not blocked by mountains, rivers, deserts, and oceans. It does not need to build expensive roads or railways like cars and trains. However, airplanes also have their own limitations, especially the limited take-off and landing sites. Aircraft, especially large fixed-wing aircraft, must rely on airport runways to take off and land. The construction scale of airport runways is large, generally more than 2 kilometers long, and occupies The space is large, and within tens of kilometers of the airport runway, there are no high-rise buildings or non-aircraft control aerial objects. Therefore, a city can only ha...

AI Technical Summary

Problems solved by technology

If the engine propeller installed in front of the end wing has enough pulling force to lift the aircraft off the ground in a "dry field" style, the aircraft can have a very good vertical take-off and landing capability, and such an aircraft can even perform various maneuvers similar to helicopters. Flight, but it will inevitably cause a large amount of redundancy in its power during the long-term cruising flight stage, which will inevitably lead to a large amount of redundancy in structural strength and aircraft weight, so short-distance takeoff / vertical landing aircraft may be the best choice
