  2. NASA Grant URC NCC NNX08BA44A Purpose To achieve and sustain Mach 1.0 to 2.0 speed, induce mixing and sustain combustion for a duration

  3. NASA Grant URC NCC NNX08BA44A Final Design

  4. NASA Grant URC NCC NNX08BA44A Intake Manifold

  5. NASA Grant URC NCC NNX08BA44A Purpose of Intake Manifold • Will assist in premixing concept • Determine if injection of hydrogen will effect nozzle performance • If no effect is determine we will introduce • Hydrogen • Silane

  12. NASA Grant URC NCC NNX08BA44A Dr. Wu Pressure Adaptor Front View

  13. NASA Grant URC NCC NNX08BA44A Pressure Testing • Will use Dr Wu pressure adaptor to determine if hydrogen gas will effect nozzle performance. • Comparing past nozzle value with intake manifold and hydrogen gas set up

  14. Pressure Reading at Nozzle Exit • Pressure gage reading • Anderson’s text: Mach 2.6 • Area ratio: 2.89

  15. NASA Grant URC NCC NNX08BA44A New ignition System • Three telsa coils ( one for each spark plug) • 13 V DC 1 Amp power source that is button operated • All wire will be insulated and routed away from any flammable sources

  16. NASA Grant URC NCC NNX08BA44A New Ignition Source:Tesla Coil • Allows for continuous spark • Strong spark across air flow • Resonant transformer circuit

  17. NASA Grant URC NCC NNX08BA44A Tesla Coil • Resonant transformer circuit • High voltage • Low current • High frequency alternating current electricity • Loosely coupled coil winding

  18. NASA Grant URC NCC NNX08BA44A Final Design

  19. NASA Grant URC NCC NNX08BA44A Future Work • Test new Intake manifold with hydrogen • Determine premixing option • Incorporate telsa coil • Develop new ignition system • Acquire silane • Finish combustion chamber
