Near Space Aircraft Energy System - Solar Array & Energy Management
Near Space Aircraft Energy System
Explore the Near Space Aircraft Energy System designed for altitudes of 20 km to 100 km. Featuring a modular solar array, energy storage, and energy management, this system offers long endurance, low cost, and reliable energy solutions for unmanned airships and aircraft.
Product Features
Near space refers to airspace at an altitude of 20 km to 100 km. Aircraft operating in this airspace are called near space aircraft, which mainly include stratospheric airships, floating balloons, and high-altitude, long-endurance airplanes.
Compared to traditional aircraft and satellites, near space aircraft have advantages such as long endurance, low cost, all-weather capabilities, and repeatable takeoff and landing. Additionally, they cannot be easily detected or attacked. These aircraft are widely used in fields like early warning detection, communication broadcasting, and electronic countermeasures.
The company has constructed an energy system architecture comprising solar array, energy storage, and energy management. It adopts a distributed modular design, achieving a closed-loop system of “energy generation - energy storage - energy supply” for different aircraft. Learn more about .
