The dynamic energy-gathering carrier aircraft catapult is externally connected with power equipment which comprises one or a plurality of power mixtures of a diesel engine, a motor and an aircraft engine.

The working principle and the using method of the dynamic energy-gathering type shipboard aircraft catapult are as follows:

the transmission gear in the host machine gear box transmits the power of the energy storage motor and the external power equipment to the clutch on the ejection traction shaft and the clutch on the homing traction shaft in real time, the clutch controls the clutch on the ejection traction shaft and the homing traction shaft to take off or release in real time through the instruction of the intelligent control module, the traction belt connected to the transmission shaft is driven to reciprocate in the runway module, the shuttle on the traction belt is dragged to move linearly to transmit the power to the carrier-based aircraft, so that the carrier-based aircraft can obtain enough takeoff acceleration, because the ejection operation of the carrier-based aircraft is carried out intermittently and instantly, when in ejection operation, the energy storage motor works and is also used as a power takeoff, the energy storage motor is converted into a generator for use during non-ejection operation, and the generator is driven by the external power equipment to generate electricity to provide extra electric power for the aircraft carrier;

when a shuttle of a certain set of catapult is connected with a carrier aircraft through a traction rod and is in a take-off standby state, an energy storage motor of the set of catapult is immediately converted into a motor by a generator, the motor is powered by an aircraft carrier power supply system, the power of a shaft is synchronously output with external power equipment, power is transmitted to a clutch on an ejection traction shaft through a transmission shaft in a gear box, after an ejection instruction is issued, the clutch on the ejection traction shaft is attracted, all power on a transmission gear is instantly transmitted to the ejection traction shaft, the ejection traction shaft winds a traction belt, the traction belt pulls the shuttle, the shuttle drags the carrier aircraft, the carrier aircraft obtains higher acceleration than that of the traditional catapult on a runway module, when the shuttle drags the carrier aircraft to an end point, the carrier aircraft leaves the ejection and lifts off, the shuttle triggers an end point sensor on the ejection runway, and the clutch on the traction shaft is released, after force taking is finished, brakes on an ejection traction shaft and a homing traction shaft are synchronously braked, a shuttle fixed point is positioned at the end point position of an ejection runway, an intelligent controller controls the brakes on the ejection traction shaft and the homing traction shaft to release, a clutch on the homing traction shaft is attracted, the homing traction shaft obtains reverse power through a transmission gear, a reverse winding traction belt pulls the shuttle back to the starting point of the ejection runway, the shuttle triggers an ejection runway starting point sensor at the starting point of the ejection runway, the clutch on the homing traction shaft releases, the brakes on the homing traction shaft and the ejection traction shaft can brake, the shuttle is positioned at the starting point of the ejection runway, and a next ejection instruction is waited;

The invention has the following outstanding excellent effects:

the dynamic energy-gathering type shipboard aircraft catapult is fundamentally different from the traditional steam catapult and the traditional electromagnetic catapult in that the traditional catapult obtains instantaneous large pressure potential energy or large electric power through static energy accumulation, the pressure potential energy and the electric power cannot represent that the pressure potential energy and the electric power can be completely converted into kinetic energy to be transmitted to the shipboard aircraft, because the steam can cause energy loss due to temperature and friction resistance of a cylinder in the cylinder acting process, the electric power is limited by the magnetic flux area of a rotor when a linear motor acts, the influence of line impedance loss and magnetic saturation is changed into a large amount of waste heat, and the kinetic energy transmitted to the shipboard aircraft is less than 30%. Related experts point out that 'the actual power consumption of a carrier aircraft ejecting 40 tons is 4000 kilowatts at most', if a static energy storage mode is adopted, 7-10 kilowatts are needed, because a steam ejector is limited by the sectional area of a cylinder, an electromagnetic ejector is limited by the magnetic flux area of a stator and a rotor, the static stored energy is larger, and the steam ejector cannot be ejected effectively under the bottleneck limitation of the sectional area of the cylinder and the magnetic flux area, so that the maximum tonnage of the steam ejector is only 40 tons at present, the electromagnetic ejector can be ejected by 30 tons at best in a working state, and the low energy utilization rate is obvious.

The dynamic energy-gathering type shipboard aircraft catapult has the greatest advantages that the power acquisition and transmission process is not limited by bottlenecks, the kinetic energy output by high-end power equipment is directly gathered in a dynamic energy-gathering mode to obtain all required kinetic energy, the required kinetic energy is directly and instantly transmitted to a shipboard aircraft, no energy conversion is needed in the middle process, only simple mechanical transmission is achieved, and therefore the energy utilization rate is close to 100%. The ejection tonnage can be arbitrarily selected according to the number of the power taking interfaces and the power of the external power equipment, and the ejection tonnage can be larger than 200 tons.

The energy-accumulating carrier-based aircraft catapult system of the energy-accumulating aircraft carrier-based aircraft has the working principle like that of the current high-speed rail motor train unit, each carriage has power, each power carriage does work in the running process, energy accumulation is realized when the power carriages are connected, the speed and carrying capacity of the motor train unit cannot be influenced by increasing more carriages, and the running speed of the motor train unit connected in series in an energy accumulation mode is dozens of times of that of the traditional train. The energy-gathered carrier-based aircraft catapult just utilizes an energy-gathered principle to gather the power of conventional power equipment with high power density and transmit the power to a carrier-based aircraft through a power transmission mechanism, so that the volume is small, the power density is high, the catapult tonnage is large, and the catapult tonnage can exceed the prior art in a dynamic energy-gathered mode.
