C Dynamic Analysis and Aeroelasticity SECTION B Answer TWO questions from this section ENG2012-N The moment of inertia of a helicopter's rotor is 320kg. m². The rotor starts from rest and at t = 0, the pilot begins by advancing the throttle so that the torque exerted on the rotor by the engine (in N.m) is modelled by as a function of time (in seconds) by T = 250t. a) How long does it take the rotor to turn ten revolutions? b) What is the rotor's angular velocity (in RPM) when it has turned ten revolutions?
1 A gasoline engine working on four stroke develops a brake power of 20.9 kW. A Morse Test was conducted on this engine and the brake power (kW) obtained when each cylinder was made inoperative by short cir- cuiting the spark plug are 14.9, 14.3, 14.8 and 14.5 respectively. The test was conducted at constant speed. Find the indicated power, me- chanical efficiency and bmep when all the cylinders are firing. The bore of the engine is 75 mm and the stroke is 90 mm. The engine is running at 3000 rpm.

As a mechanical engineer, you were asked by your supervisor to monitor the operation of 4-stroke engine; as a result you got the following readings: > Imep = 780 kN/ m2 > Engine speed = 800 rpm > Brake Power 30 kW %3D %3D > nm = 85 % > B/S 0.7 You noticed also, that the inlet valve opens 10° before TDC and closes40° after BDC and it takes 0.0035 second after ignition for the charge to gain maximum pressure. Depending on the above readings, find the following engine parameters: a. The crank angle when the spark occursfor the maximum pressure to be at TDC b. The time period in second of inlet valve opening during one cycle c. The diameter of the engine d. The average piston speed 1 Upload file
