Slope downward-sliding takeoff platform for carrier-based aircraft, application aircraft carrier and realization method

Abstract

The invention discloses a slope downward-sliding takeoff platform for a carrier-based aircraft, an application aircraft carrier and a realization method, relates to the field of naval weapons and solves the technical defects caused when the carrier-based aircraft takes off by adopting a skiing-jumping takeoff method. The slope downward-sliding takeoff platform for the carrier-based aircraft comprises a slope curved-surface runway. A support carrier plate is connected with the slope top end of the slope curved-surface runway. A percussive carrier-based aircraft tail hook fixing device which is used for being matched with the tail hook of the carrier-based aircraft when the carrier-based aircraft starts to run is arranged on the support carrier plate. The support carrier plate is additionally connected with a lifting platform. Due to the gravity of the carrier-based aircraft and the fall of the slope curved-surface runway, gravity acceleration is added onto the carrier-based aircraft on the basis of acceleration through engine thrust of the carrier-based aircraft, the goals of saving fuel, shortening takeoff distance, increasing load and increasing combat radius and combat force are achieved, and the daily operation efficiency to expense ratio is superior to the existing takeoff method.

Description

technical field [0001] The invention relates to the field of naval weapons, in particular to an accelerated take-off platform for carrier-based aircraft of an aircraft carrier. Background technique [0002] At present, on known aircraft carriers, there are mainly two take-off methods for fixed-wing carrier-based aircraft: one is to use a steam catapult device to make the fixed-wing carrier-based aircraft take off from the deck. low and highly efficient. The disadvantages are: 1. High cost-efficiency ratio, 2. Difficult to manufacture, 3. Huge volume takes up limited space under the deck, 4. High requirements on the strength of the carrier aircraft structure, especially the front landing gear; the other is to use the ski jump The take-off method is to achieve the acceleration of the take-off stage by strengthening the carrier-based aircraft's own power. This method needs to set up a 10-15-degree upward sliding warp at the front of the aircraft carrier deck to increase the li...

Problems solved by technology

The disadvantages are: 1. High cost-efficiency ratio, 2. Difficult to manufacture, 3. Huge volume takes up limited space under the deck, 4. High requirements on the strength of the carrier aircraft structure, especially the front landing gear; the other is to use the ski jump The take-off method is to achieve the acceleration of the take-off stage by strengthening the carrier-based aircraft's own power. This method needs to set up a 10-15-degree upward sliding warp at the front of the aircraft carrier deck to increase the lift. During the take-off process, the aircraft carrier needs to sail against the wind at a speed of about 50km / h to achieve the purpose of speeding up

Although the aircraft carrier adopting the ski-jump take-off method and device does not have high requirements for the strength of the hull structure and equipment and the front landing gear of the carrier-based aircraft, and has a lower entry threshold, the disadvantages are: 1. The carrier-based aircraft is required to have relatively high High thrust-to-weight ratio (the ratio of the thrust of the carrier-based aircraft engine to its own weight)

2. Since the aircraft carrier deck limits the length of the take-off runway, the payload of the carrier-based aircraft, the range and the amount of ammunition of the carrier-based aircraft are limited, the combat effectiveness is weak, and the take-off of the fixed-wing early warning aircraft with lower thrust becomes more difficult
