一种混合动力平流层飞艇
By introducing a hybrid power system combining radioisotope thermoelectric generators (RTGs) and solar panels into stratospheric airships, the problem of decreased nighttime flight performance has been solved, achieving stable nighttime flight and reducing the need for solar panel area, thereby improving the airship's range and shape stability.

AI Technical Summary
Existing stratospheric airships cannot generate electricity at night due to the inability of their solar arrays to do so, and therefore rely on batteries for power, which leads to a decline in flight performance and affects flight speed.
By introducing a radioisotope thermoelectric generator (RTG) as an auxiliary power source, combined with solar panels, energy is provided during the day and at night. The RTG has an ultra-long range, requires no maintenance, and ensures that flight performance is not reduced at night.
This technology enables the airship to maintain flight performance at night while reducing the area required for solar panels, improving its endurance and stability, and preventing shape changes caused by internal and external pressure differences.
