| Abstract: |
| Objective To research the electrostatic protection scheme of reusable launch vehicles. Methods According to the working environment characteristics and the space electrostatic discharge environment encountered by reusable launch vehicle, the mathematical model of the space charge was established to calculate the electrostatic charge potential of charged ions on the surface of reusable launch vehicle. On this basis, the static characteristics of a large number of materials were analyzed, and the integration scheme of electrostatic protection layer and electrical equipment were proposed. Results Carbon fibre composite was taken as an electrostatic protection layer to connect ground bus of large section to provide equipotential of low resistance and large charge capacity for electrical equipment of vehicle. Conclusion The scheme can effectively resist the disturbance caused by static electricity, and provide a reliable, safe and anti-interference electromagnetic environment for the electronic equipment. In addition, the method is simple, which greatly reduces the weight of the vehicle. |
