PPT-Nozzleless Propulsion System

In the conventional solid rocket motor the propellant is burnt inside a rocket chamber and the hot gases thus generated are accelerated to supersonic condition through a convergentdivergent type nozzle The heat energy of the gases is converted into kinetic energy inside the nozzle. Propulsion System. A machine that produces thrust to push an object forward. The amount of thrust depends on the mass flow through the engine and the exit velocity of the gas.

The human power submarine is a very comprehensive project that involves the use of concepts learned from different courses of the mechanical engineering bachelor’s degree. The project consist in the design and analysis of a human powered submarine. By doing this project the institution will increase its participation in international competitions and also will enhance the engineering education of its students.. Cold Gas System. How the System Creates Propulsion. The system creates propulsion using an inert gas such as Nitrogen or Helium as the fuel.. The gas is stored under high pressure, then sent to the thruster which releases the gas.. Reaction Wheel. How it creates Propulsion. Reaction wheels actually do NOT create propulsion, they only create rotation.. Main components of the system. Electric motor. Flywheel. When would it be most effective?. The "jet" or exhaust power (P. jet. ) of any thruster is: . P. jet. = 1/2 g. c. I. sp. F . Thus, for a situation where we wish to fix the thrust at a constant value, as specific impulse increases, the jet power must also increase. . A machine that produces thrust to push an object forward. The amount of thrust depends on the mass flow through the engine and the exit velocity of the gas. Airplane Propulsion Systems. Propeller. Allie Burton. November 21, 2015. Creating Propulsion.
