Jet-propelled combined power single-person aircraft

Abstract

The invention provides a jet-propelled combined power single-person aircraft. The jet-propelled combined power single-person aircraft comprises a supporting framework, and turbojet engine assemblies used for providing vertical thrust for the aircraft and ducted fan assemblies used for providing horizontal thrust for the aircraft are symmetrically arranged on the two sides of the supporting framework; the rear side of the supporting framework is connected with a fuel tank used for providing fuel for the turbojet engine assembly, and the front side of the supporting framework is connected with a fixing assembly used for being connected with the back of an operator. The supporting framework is further provided with a controller used for controlling the operation state of the turbojet engine assembly and the operation state of the ducted fan assembly and a sensor used for sensing the human body action of an operator. And the sensor is in signal connection with the controller. The jet-propelled combined power single-person aircraft provided by the invention is simple in structure, reasonable in layout of the power assembly and capable of realizing flexible conversion of various flight postures of the aircraft.

Description

technical field [0001] The invention relates to the technical field of surgical machinery, in particular to a jet-type combined power single-person aircraft. Background technique [0002] A single-person aircraft refers to a light-weight flying device that drives a single person, which has high research value and practical significance. It has the characteristics of small size, low cost, flexible operation, etc., and can be widely used in medical and emergency, fire rescue, tourism and leisure and other fields. [0003] According to the classification of power source, it can be divided into unpowered type, rotor type, wingless jet type and fixed wing jet type. Among them, the typical representative of unpowered single-person aircraft is winged flight, which is mainly used in the entertainment field of extreme sports. The risk factor and limitation of the method are too high, obviously it cannot be widely used. Although the fixed-wing jet can fly forward fast, its wing area...

Problems solved by technology

Among them, the wearable type has a close relationship with the human body, such as the "Daedalus 1" designed by a British inventor, but its disadvantage is that the entire system requires human support and requires a lot of physical strength for the operator; while the current foot-operated type The main problem is that it needs to use both feet to balance the flying platform, and even needs to complete various attitudes of the aircraft through the movements of the feet, which consumes a lot of physical energy

[0005] In addition, the "JB-10" flight backpack with two jet engines launched by Martin Flight Jet Pack Company mainly provides all the power sources through the micro turbojet engine, that is, the micro turbojet engine needs to provide vertical and horizontal For the thrust in two orthogonal directions, if we change the direction of the cladding separation nozzle and let the airflow jet out from an oblique direction, on the one hand, a small part of the energy of the injection thrust will be converted into heat energy at the separation nozzle, which makes The thrust is affected. On the other hand, the thrust in the oblique direction needs to be greater to meet the thrust requirements in the orthogonal direction. For the same type of turbojet engine, the greater the thrust, the larger the engine volume; the power device in this structure needs to drive the separation nozzle Devices that swing back and forth, such as servo servos or other pneumatic and hydraulic structural methods to achieve swing functions, and adding servo servos and other driving structures to the turbojet engine will undoubtedly take up more space. From the perspective of structure, it will greatly increase the volume of the aircraft, which is far from the design concept of advanced lightweight and portable aircraft.
