Heat Transfer in Airborne Equipment - Theoretical Model
2014 (English)Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
Abstract [en]

In this thesis heat transfer theory is used to develop the theoretical model to predict the temperature of the equipments used in Esrange balloon flights. The worst cases for the equipment are identified by selecting the worst environmental conditions along with the maximum and minimum power modes of equipment. The thermal control techniques are investigated to keep the temperatures of the equipment within the operating range. Transient analyses are also performed for the total flight time on the equipment to incorporate the effect of variation of external environment with altitude. Based on the analyses, a thermal control technique is suggested for the worst cases. The theoretical model is verified through a test setup as well as comparing the analyses results with data from actual flights.
