Embodiment Construction

[0027] The present invention will be further elaborated and illustrated below in conjunction with the drawings and specific embodiments. The technical features of the various embodiments of the present invention can be combined accordingly without conflict with each other.

[0028] Such as Figure 1~3 As shown, an unmanned aerial vehicle two-point rocket booster launcher includes a thrust frame 1 for installing a booster rocket 9, a base 11 installed on a body 8 and a pin shaft. Two ball sockets 10 and a hanging point 6 are provided on the base.

[0029] Different from the traditional thrust frame, the thrust frame 1 in this embodiment is fixedly provided with two side-by-side thrust rods, namely the first thrust rod 4 and the second thrust rod 5 respectively. Such as Figure 5 As shown, one end of the first thrust rod 4 and the second thrust rod 5 is connected to the body of the thrust frame 1, and the other ends are respectively embedded in a ball socket 10. In addition, a con...

Abstract

The invention discloses a two-point-type rocket assisting launcher of an unmanned aerial vehicle and a method thereof, and belongs to the field of aircrafts. The two-point-type rocket assisting launcher of the unmanned aerial vehicle comprises a thrust frame for installing a booster rocket and a bottom base and a hanging hook ring which are installed on an unmanned aerial vehicle body. The thrustframe is fixedly provided with two thrust bars and a hanging hook. The bottom base is provided with two ball sockets and a hanging point. The hanging hook is hanged on the hanging hook ring. The top parts of the two thrust bars are supported in the ball sockets. The hanging hook, the thrust bars and the unmanned aerial vehicle body form a triangle supporting structure. The thrust bars transmit a rocket assisting thrust to the unmanned aerial vehicle body through the two ball sockets. The hanging point is used for connecting a sling for determining a thrust line. The thrust frame is further provided with a connecting base used for connecting a thrust line measuring device. The two-point-type rocket assisting launcher of the unmanned aerial vehicle uses a two-point boosting mode, the stabletriangle is formed by two thrust points and one hanging hook point, the gravity is balanced and the influence of the ground effect to the relative position of the rocket and the unmanned aerial vehicle body in a launching initial stage is eliminated, so the accuracy of the relative position between the rocket and the unmanned aerial vehicle body is guaranteed.

Description

Technical field [0001] The invention relates to the field of aircraft, and in particular to a two-point rocket-assisted launch device for an unmanned aerial vehicle and a method thereof. Background technique [0002] Drones are currently a hot research area in aircraft and are widely used in aerial photography, agriculture, plant protection, micro selfies, express transportation, disaster relief mapping, news reporting, power inspections, military and other fields. Among them, fixed-wing UAVs require external power to propel and launch them in the early stages of takeoff. There are many ways to launch drones, such as hand-thrown, airborne launch, vehicle-mounted launch, ejection and zero-length rocket boost. Zero-length boost drone launch is the most flexible launch method for drone applications. [0003] At present, many small UAVs basically use rocket single-point boost (one rocket corresponds to one boost point). The single-point boost method is a base with a conical s...
