Question

The jet transport aircraft DC-9-30 with 100 seats is cruising at ISA 30,000 ft altitude. This aircraft that has a mass of 44,000 kg at the beginning of cruising flight is planned to descend and then land when 7,000 kg of its fuel is consumed. Turbofan engines of this aircraft (JT8D-1S) have fuel specific consumption of 0.82/hr. Other features of this aircraft are $C_{D0}$=0.02, e=0.82, b=29 m, S=90 m$^2$ Air density at ISA 30,000 ft is 0.459037608 kg/m$^3$ What is its maximum range and endurance to the amount of fuel consumed at this altitude? You need to submit the working out solution in the submission box. You can type the question in the answer box OR upload the solution by clicking the Embed image icon and choose the option of CANVAS and then upload the photo file of your solution.
