System and method for transmitting energy to rocket based on microwave

Abstract

The invention provides a system and method for transmitting energy to a rocket based on microwave. A transmitting array device and a receiving array antenna are aligned and reach a preset alignment condition. An energy conversion device performs the rectification, filtering and transformation of the commercial power and converts the direct current into a microwave through the conversion device. Acontrol computer controls the transmitting array device to transmit the converted microwave to the receiving array antenna through the transmitting array device. The receiving array antenna receives the microwave transmitted by the transmitting array device, and a TR converting component converts the received microwave of the receiving array antenna into a current. A synthesizer collects the current converted by the TR converting component, and enables the converted current to form a combined current and transmitted to the electric energy conversion device. The electric energy conversion device transforms and filters the combined current for use on the instrument and the electronic device on the rock. The system achieves the wireless transmission between the rocket and the ground, avoids aconventional rocket-ground power supply connector and cable, improves the reliability, reduces the operation, and improves the preparation efficiency of the launch.

Description

technical field [0001] The invention relates to the technical field of rocket-ground interconnection of launch vehicles, in particular to a microwave-based wireless arrow-to-arrow energy transfer system and method for realizing a distance of 100 meters. Background technique [0002] During the ground test of the existing launch vehicle, the ground-to-rocket power supply supplies energy to the equipment on the rocket in a wired manner through cables. Considering redundant and reliable design, margin design, voltage line drop control, power supply cable design is relatively cumbersome; in addition, before launching, it is necessary to connect the arrow-ground connector. The risk of success and the possibility of hitting the engine nozzle after falling off. In order to reduce weight, simplify operation and improve launch efficiency and reliability, it is necessary to consider a new arrow-ground connection mechanism or mode. [0003] Although there is microwave-based wireless ...

AI Technical Summary

Problems solved by technology

[0003] Although there is microwave-based wireless transmission technology at present, based on the energy transmission process from the ground to the rocket, the control of the transmission angle and the transmission method of the transmission angle affect the effect of energy transmission. If there is an angle deviation, the transmitted energy will not be able to realize the rocket's own operation. needs, which affect the operation of the rocket in the near-Earth range
