A buffer device and buffer method for an ultra-low-altitude sea-skimming unmanned target drone

Abstract

The invention discloses a super low-altitude sea-skimming unmanned target aerial vehicle buffer device and buffer method. The device comprises a main rocker arm, an auxiliary rocker arm, a surfboard,a buffer assembly, a slide block assembly, a bracket assembly, a main rocker arm and buffer connecting shaft, a main rocker arm and auxiliary rocker arm mounting shaft, and a main rocker arm and surfboard mounting shaft. The buffer device uses the combination of the rocker arm mechanism and the buffer, and absorbs the energy of the surfboard colliding with the water by the buffer during the sea-skimming flight of the sea-skimming unmanned target aerial vehicle, and reduces the overload on the fuselage structure of the sea-skimming unmanned target aerial vehicle so as to allow the sea-skimmingunmanned target aerial vehicle to fly at a lower flying height. The combination of the rocker arms and a slide rail reduces the front-rear moving distance of a point of contacting water relative to the center of gravity of the unmanned target aerial vehicle during the process that the surfboard contacts the water, thereby reducing the flight control difficulty of the sea-skimming unmanned target aerial vehicle after contacting the water. The buffer device can be highly folded, has a buffering load-decreasing function, and can be lowered by the buffer assembly.

Description

technical field [0001] The invention relates to the field of ultra-low-altitude sea-skimming flight buffering and working methods, in particular to a buffering device and buffering method for an ultra-low-altitude sea-skimming unmanned target drone. Background technique [0002] Unmanned target drone is an important branch of the drone family. It is mainly used to simulate the attack process of combat aircraft, missiles, and other threat targets. It provides realistic air targets for sensors, weapon tests and training of air defense weapon systems. It is an indispensable and important support equipment in the development, test, appraisal and training of weapon system. [0003] With the advancement of technology, modern combat aircraft, anti-ship missiles, and land-strike cruise missiles often adopt the "ultra-low-altitude" flight penetration method, which can not only use the cover of sea and ground clutter, but is not easy to be detected by the enemy's warning radar. Even ...

Problems solved by technology

However, in the late 1990s, my country began to conduct research on the ultra-low-altitude sea-skimming flight of unmanned target drones, which is far behind the actual application requirements.

Firstly, a bomber with an inlet to miss the target was used for the test, but the best sea-skimming flight that can be achieved is at a relative altitude of 20m, and it depends heavily on the pilot's flying level, so the success rate is low

Then use the unmanned target drone to fly directly at low altitude and sea-skimming, but due to the limitations of the overall design and flight control technology, it can only achieve a relative height of 25m at present, which is difficult to meet the requirements of various tests and training for sea-skimming flights less than 15m or even 5m requirements
