A system and method for launching a large-diving deep-water unpowered aircraft

Abstract

The invention discloses a large-diving-depth underwater unpowered aircraft transmitting system and method. The transmitting system comprises an underwater autonomous measuring and control system, a transmitting cylinder with a front cover, a catapult arranged in the transmitting cylinder, and an aircraft arranged in the transmitting cylinder, wherein the transmitting cylinder, the catapult, the aircraft and the measuring and control system integrally adopt an axial deflection design; compared with a mass center, the axial buoyant center is closer to the front cover of the transmitting cylinder; the transmitting system is fixed to an underwater platform, after the transmitting system is separated from the underwater platform, the situation that upward buoyance is greater than the sum of gravity and floating resistance is changed into the situation that the upward buoyance and the sum of the gravity and floating resistance gradually tend to be balanced; the aircraft is fixed on one side of a sealing bottom plate in the transmitting cylinder, and the other side of the sealing bottom plate is connected with the catapult; and after the front cover is opened, the catapult produces thrust to push the aircraft to slide in the direction from the transmitting cylinder to the front cover, and the aircraft slides from the transmitting cylinder. According to the large-diving-depth underwater unpowered aircraft transmitting system disclosed by the invention, the maximum transmitting depth of the transmitting system is not less than 200 meters; and in the transmitting system, the aircraft does not bear water pressure limit directly, so that the aircraft is low in design condition requirements, and high in portability.

Description

technical field [0001] The invention belongs to the technical field of launching a submarine-launched aircraft, and in particular relates to a launching system and method for a large-submerged deep-water unpowered aircraft. Background technique [0002] The underwater unpowered aircraft launch system usually includes an underwater autonomous test launch control system, a launch tube with a front cover and a catapult installed in the launch tube, and also includes an aircraft set in the launch tube, and the underwater autonomous test launch The control system includes the test, launch and control platform equipment and the launch, test, launch and control equipment installed in the aircraft. [0003] The aircraft is placed in a closed launch tube, which is pre-fixed on the underwater platform, and the underwater autonomous measurement and control system issues a command to release the launch tube, using the launch to release the power and the buoyancy and initial release of t...

Problems solved by technology

The launching system and method for realizing the launch of the aircraft by the relative movement of the launch tube of the aircraft, the dynamic separation of the separation of the launch tube of the aircraft can make the aircraft ignite after it emerges from the water, thereby increasing the range of the aircraft and the safety of ignition, but under the condition of a large diving depth of 200 meters To realize the unmanned platform launch aircraft, the disadvantages of this technology are: 1. The launch tube has no power, and the water exit speed is lower than that with power. It needs to increase the water exit speed, and the stability is relatively poor; 2. Underwater unmanned platform launch The aircraft is faced with the problem of whether the information guarantee is reliable when unmanned operation; 3. The launching tube is affected by the large working depth in the water, unpowered floating, and unpowered attitude control. The process is susceptible to interference, and it is necessary to create a reasonable and reliable environment for the separation of the aircraft launcher, including the speed of the water exit and the deviation of the attitude angle. After the launching tube is out of the water to a suitable height, it is necessary to separate the aircraft from the launching tube as soon as possible and as soon as possible. Only by meeting this series of requirements can the launch be completed reliably; It affects the internal ballistic performance of the catapult and cannot be launched reliably, and even leads to catastrophic consequences; 5. The launch measurement, launch and control equipment is installed in the aircraft to increase the negative mass of the aircraft
