Design a solid or hybrid upper stage propulsion module (pm) with the capability to boost a 181 kg payload from a 352 km circular orbit to a 704 km circular orbit. of the 181 kg payload, 125 kg is allocated for the experimental satellite, leaving no more than 56 kg for the pm. show your design’s a) throat area b) exit area c) exhaust velocity d) mass flow rate state any assumptions that you make. hint, it takes 0.52 m/s to raise the orbit 1 km at an altitude of 352 km.

Afour cylinder four-stroke in-line engine has a stroke of 160mm, connecting rod length of 150mm, a reciprocating mass of 3kg and its firing order is 1-3-4-2. the spacing between cylinders is 100mm. i. show that the engine is in balance with regard to the primary inertia forces and primary 3. a and secondary inertia couples. li determine the out of balance secondary inertia force ii. propose ways of balancing this out of balance force and discuss the challenges that will arise

Which of the following ziegler nichols tuning methods the response of the controller to a step input should exhibit an s-shaped curve? a)-open loop mode b)-closed loop mode c)-both modes (open & closed) d)-none of the modes (open & closed)
