Steam catapult for carrier-borne aircraft and catapulting method thereof

Abstract

The invention provides a steam catapult for a carrier-borne aircraft and a catapulting method thereof. The steam catapult comprises a take-off runway, a pulley, a pulley channel, a main traction winch, an auxiliary traction winch, a catapulting cylinder and a catapulting programmable controller, wherein the pulley channel is formed in the middle of an aircraft carrier ski-jump take-off runway or a horizontal take-off runway; the pulley is arranged in the pulley channel; the main traction winch and the auxiliary traction winch are arranged in a cabin below the take-off runway; the steel cables of the main traction winch and the auxiliary traction winch are connected with the front and rear ends of the pulley respectively; and the catapulting cylinder is arranged at the bottom of the pulley channel positioned at the starting point of the take-off runway. The catapult take-off of the carrier-borne aircraft is realized in pneumatic and mechanical traction modes, the defects that the conventional steam catapult has large volume, high energy consumption and short service life and is difficult to process are overcome, and a brand-new catapult for the carrier-borne aircraft is provided for aircraft carrier construction in China.

Description

technical field [0001] The invention relates to a catapult for military equipment or an aircraft carrier, in particular to a steam catapult for an aircraft carrier and an ejection method thereof. Background technique [0002] At present, the shortcomings of the steam catapult used by the US military are: the two cylinders of the steam catapult are open cylinders, the two pistons are fixed together, and the shuttle on the runway is directly driven by the hook on the piston , the ejection velocity is constant. The reset of the shuttle on the runway is completed by another set of steam-driven devices. Therefore, the equipment is bulky, occupies a large space, consumes a lot of energy, has high manufacturing costs, high operating costs, and high maintenance costs. Shuttle, so the shuttle connecting plate is set on two parallel pistons to protrude from the slotted cylinder of the 98.5-meter factory. Due to the existence of long slots, it not only increases the difficulty of cyli...

[0002] At present, the shortcomings of the steam catapult used by the US military are: the two cylinders of the steam catapult are open cylinders, the two pistons are fixed together, and the shuttle on the runway is directly driven by the hook on the piston , the ejection velocity is constant

The reset of the shuttle on the runway is completed by another set of steam-driven devices. Therefore, the equipment is bulky, occupies a large space, consumes a lot of energy, has high manufacturing costs, high operating costs, and high maintenance costs. Shuttle, so the shuttle connecting plate is set on two parallel pistons to protrude from the slotted cylinder of the 98.5-meter factory. Due to the existence of long slots, it not only increases the difficulty of cylinder processing, but also must use a special The sealing device seals the slit to ensure the steam pressure of 200 N/cm2 in the cylinder. Due to the existence of long slits, the cylinder is easily deformed during use, resulting in a decrease in cylinder power and affecting the service life
