Safe carrier landing and high-efficiency energy recycling device of carrier aircraft

Abstract

A safe carrier landing and high-efficiency energy recycling device of a carrier aircraft is characterized by comprising a resistance pad component, an oil squeezing component, an oil return component, an oil supplementing component, an oil circulation control component and a hydraulic-electric conversion component. Squeezed oil is transmitted to the hydraulic-electric conversion component from the resistance pad component via the oil squeezing component, output of the hydraulic-electric conversion component and input of the oil return component are connected so as to form oil channel circulation, output of the oil supplementing component is connected with the oil return component, the oil circulation control component controls the speed of oil circulation, and the hydraulic-electric control component converts oil pressure mechanical energy into electric energy. The safe carrier landing and high-efficiency energy recycling device is reasonable in structure, light in weight, easy in maintenance and reliable, safe and steady in braking process, realizes safe carrier landing and high-efficiency energy recycling, occupies few decks of a warship, and realizes energy conservation and emission reduction. In addition, tail hooks of the aircraft for being hooked with arresting ropes can be omitted, and accidents of unhooking of the arresting rope are avoided. Besides, requirements of 'front blocking and rear dragging' and repeated setting of a plurality of stopping devices are omitted, accident possibility is reduced, the weight of a carrier is lightened, and the number of warships parked on decks is increased. Further, longitudinal strength of warship bodies does not need to be specially strengthened.

Description

[0001] technical field [0002] The invention relates to a device, in particular to a device for safe landing and energy efficient recovery of a carrier aircraft. Background technique [0003] The purpose and task of the aircraft carrier is to serve as a rapid lifting platform for carrier-based aircraft. my country's new-generation aircraft carrier can carry 60-70 carrier-based aircraft, including 48 multi-purpose fighters, 4 air early warning aircraft, 4 air refueling aircraft, and 6-8 anti-submarine aircraft. The best interval is one aircraft on the glideslope every 50 seconds. The landing of a carrier-based aircraft on the deck is a process full of various dangers. Going forward, backward, or left or right will cause the danger of rushing out of the deck or colliding with other aircraft on the ship. The waves are low and the roll of the deck is too large, which will also cause the carrier-based aircraft to capsize and fly when the wheels touch the deck. If the initial sp...

AI Technical Summary

Problems solved by technology

Carrier-based aircraft in World War II had an accident for every 50 landings

[0006] 1. The kinetic energy of landing is increased. At present, when a carrier-based aircraft "crashes" and "hits the deck", it will have a great impact on the ship and increase the sinking speed of the landing gear. The design standard of the landing gear is With a sinking speed of 4.5m / s, the carrier-based aircraft requires the landing gear to withstand a sinking speed of 6m / s, which will undoubtedly increase the structural weight of the landing gear and the displacement of the aircraft carrier

[0007] 2. The landing speed increases, and the landing zone deck continues to lengthen

[0008] 3. The types of landing aircraft have increased, and the number has increased. During World War II, aviation was not only equipped with fighter jets and bombers, and there were no "big mac" air pre-warning aircraft, refueling aircraft and other support aircraft.

[0010] 5. When the aircraft is descending, the tail hook often cannot be centered to hang the wire arresting wire

[0012] 7. The strength of the arresting cable is low. Based on the limit of physical strength, the wire arresting cable requires a landing speed of less than 130 knots. However, the horizontal speed of carrier-based aircraft is generally 135 knots when landing. The safety factor of the cable brings troubles to the device

[0022] At present, carrier-based attack aircraft, airborne early warning aircraft and other support aircraft cannot or have not all adopted vector thrust technology. From an engineering point of view, carrier-based aircraft that do not adopt vector thrust technology are not easy to reduce the landing energy and have high landing accuracy. Increased range and qualitative changes in ship landing safety
