hai archita,ac drive means operate with a current that alternates in the direction of flow 60 times per second HZ. If this frequency of alternation is changed, the speed of the motor changes. By controlling the AC frequency with a variable frequency drive, you control speed. A proper voltage to frequency ratio V/HZ must be supplied. For most industrial motors manufactured in the US this ratio is 460

model rocket is subjected to the forces of weight, thrust, and aerodynamics during its flight. The thrust force is supplied by a small solid rocket engine.There are two main categories of rocket engines; but the propellant will burn when exposed to an external source of heat. Some type of igniter is used to initiate the burning of a solid rocket motor at the end of the propellant facing the nozzle. As the propellant
