A fast mail delivery drone uses an ideal jet-propulsion cycle to fly in air of free-stream temperature T₁ = 314 K at speed V₁ = 84 m-s-1. The inlet, compressor, turbine, and nozzle flows are isentropic. The engine uses 93-4 = 202 kJ-kg-1 of specific heat in the combustor and the tailpipe exit nozzle is choked. By making cold-air-standard assumptions, estimate the specific thrust. State your answer in Ns-kg-1 to zero decimal places and enter the numerical value only.

QUESTION 5 A fast mail delivery drone uses an ideal jet-propulsion cycle to fly in air of free-stream temperature T₁ = 314 K at speed V₁ = 84 m-s-1. The inlet, compressor, turbine, and nozzle flows are isentropic. The engine uses 93-4 = 202 kJ-kg-1 of specific heat in the combustor and the tailpipe exit nozzle is choked. By making cold-air-standard assumptions, estimate the specific thrust. State your answer in Ns-kg-¹ to zero decimal places and enter the numerical value only.
