Abstract : Solar energy is the ideal power choice for long-endurance stratospheric airships. The output performance of solar array on
stratospheric airship is affected by several major factors: flying latitude, flight date, airship’s attitude and the temperature
of solar cell, but the research on the effect of these factors on output performance is rare. This paper establishes a new
simplified analytical model with thermal effects to analyze the output performance of the solar array. This model consisting
of the geometric model of stratospheric airship, solar radiation model and incident solar radiation model is developed using
MATLAB computer program. Based on this model, the effects of the major factors on the output performance of the solar
array are investigated expediently and easily. In the course of the research, the output power of solar array is calculated for five
airship’s latitudes of 0°, 15°, 30°, 45° and 60°, four special dates and different attitudes of five pitch angles and four yaw angles.
The effect of these factors on output performance is discussed in detail. The results are helpful for solving the energy problem
of the long endurance airship and planning the airline.
