Why is low thermal conductivity important for aircraft systems?(a) To increase the strength of the material(b) To protect from excessive heating(c) To keep aircraft warm for passengers(d) For oxygenThis question was addressed to me in semester exam.The query is from Materials Selection in portion Materials Selection of Aerospace Materials & Processes

Answer»

The correct answer is (b) To PROTECT from excessive heating

The EXPLANATION: Thermal conductivity of a material is the rate at which it conducts heat. Low thermal conductivity is IMPORTANT because it prevents the systems from excessive heating hence preventing FAILURE. It does not affect the OXYGEN levels or increase the strength.
