Low-wind-resistance coil, preparation method of low-wind-resistance coil and aircraft adopting low-wind-resistance coil

Abstract

The invention relates to a coil and a preparation method thereof, and aims to solve the problems that the attitude control stability and flight performance of an aircraft are influenced due to a largeair resistance coefficient value of a wireless charging transceiving coil of the aircraft in the prior art, and the greatly increasing servicing mass of the aircraft by using a large-diameter copperlitz wire severely influences the aircraft performance. According to the aircraft adopting the low-wind-resistance coil and the preparation method of the aircraft, the low-wind-resistance coil is integrally in a circular ring body shape, the section of the circular ring body is oval, the short axis of the oval is arranged in the axial direction of the circular ring body, and the circular ring bodyis of a hollow structure formed by winding a litz wire; the invention discloses an aircraft adopting a low-wind-resistance coil. The low-wind-resistance coil serves as a receiving coil to be installed on a support of the aircraft in a sleeving mode. The preparation method of the coil comprises the following steps: firstly winding the planar coil, manufacturing the planar coil into the bent coil by using two dies, then bonding the two bent coils, and connecting in parallel to form the complete low-wind-resistance coil.

Description

technical field [0001] The invention relates to a coil and a preparation method thereof, in particular to a low wind resistance coil and a preparation method thereof, and an aircraft using the low wind resistance coil. Background technique [0002] The wireless charging receiving coil of the aircraft completes energy reception during the charging process of the aircraft, and also needs to meet the aerodynamic low-resistance characteristics at the same time, so as not to reduce the flight performance of the aircraft. [0003] In the prior art, the transceiver coil used in the wireless charging system often only considers the electrical performance. Therefore, the design of the transceiver coil takes high efficiency, low cost, and mature technology as the main design input, and rarely considers the aerodynamic effect. Therefore, The air resistance coefficient of the transceiver coil is relatively large, which will affect the attitude control stability and flight performance of...
