A jet aircraft with mass of 631,405.4 kilograms is flying straight downward. At an instant the plane's engine is producing an downward thrust (force) of 3,329,281.8 Newtons and air resistance is exerting a force of 714,785.5 Newtons upward. What is the acceleration of the plane in m/s2 at that instant? Note: In this problem, we define "down" as positive.

. A turbofan aircraft engine is flying at 720 km/h at an altitude of 6100 m, where the ambient conditions are 50 kPa and -12°C (a negative value). The pressure ratio across the compressor is 13, and the turbine inlet temperature (TIT) is 1330 K. Assuming ideal operation for all components and constant specific heats for the air at room temperature (cold air model). (a) Sketch the T-s diagram of the cycle, and determine: (b) The Mach number of the...

A solid 1.25 in. diameter shaft is used in an aircraft engine to transmit 140 hp at 2930 rpm to a propeller that develops a thrust of 1700 lb. Determine the magnitudes of the principal stresses and the maximum shear stress at any point on the outside surface of the shaft. Enter the principal stresses at any point on the outside surface of the shaft. Use the sign convention that a tension normal stress is positive and a compression normal...
