Which of the following is true?(a) Lowest possible empty weight fraction in practice is zero(b) F-35 aircraft has the highest possible empty weight fraction(c) Empty weight fraction will be different for different type of aircrafts(d) Empty weight fraction is always same for each aircraftI have been asked this question in examination.My query is from Conceptual Sketch Sizing topic in division Conceptual Sketch Sizing of Aircraft Design

Answer»

The correct answer is (c) Empty weight fraction will be different for different type of aircrafts

The best EXPLANATION: Empty weight is weight of the power plant, AVIONICS, sub-system of AIRCRAFT etc. Hence, in practical it cannot be zero. F-35 is a military class aircraft which is not designed to have highest possible empty weight fraction. Empty weight fraction is not CONSTANT. For, different aircraft, it will be different according to their requirements.
