摘要

Expendable Launch Vehicles are designed with a single mission perspective. Reusable Launch Vehicle design aims for reusability and maintainability for multiple missions. Power system of such missions has features that are distinctive from operational launch vehicles like PSLV & GSLV. The instrumentation, Navigation Guidance & Control, pyro and actuation system power are derived from Li ion batteries, which is a notable feature of Reusable Launch Vehicle-Technology Demonstrator. RLV-TD power system consists of a unified redundant power bus running throughout the vehicle unlike conventional launch vehicles. This paper discusses the configuration of electrical power distribution system of RLV-TD highlighting the constraints and design considerations. Load requirements and power characteristics are defined. Techniques adopted for fault protection and redundancy to achieve reliability are discussed. Battery capacity estimation method followed for continuous and pulse current requirements are described.
