1.	For a given rubber engine, determine fuel burn at combat if combat time is 2.5min.(a) 2.5CT unit(b) 2.5(c) 2.89 unit(d) 2.63 kgThe question was posed to me during an interview.I need to ask this question from Rubber-Engine Sizing in chapter Initial Sizing of Aircraft Design
Answer» Correct ANSWER is (a) 2.5CT UNIT Best explanation: GIVEN, combat time d = 2.5 min. Since SFC and thrust are not mentioned we will CONSIDER their notation as C and T respectively. Now fuel burn = SFC * Thrust Combat time = CT*2.5 unit.
