Claims
- 1. A turbogenerator system, comprising:
a turbine mounted for rotation on a shaft a motor/generator coupled with said shaft for rotation therewith; a combustor for combusting fuel and compressed air to generate combustion gases for rotating said turbine; a compressor providing compressed air; an injector having at least one opening to admit the compressed air from said compressor, the injector connected to said combustor to inject fuel and compressed air into said combustor; a piston slidably covering the at least one opening providing a variable entry to the compressed air; and a pressure actuator associated with said piston and responsive to pressure in the combustor for determining size of the variable entry.
- 2. The turbogenerator system of claim 1, wherein said opening comprises circular orifice.
- 3. The turbogenerator system of claim 1, wherein said opening comprises elongated slits.
- 4. The turbogenerator system of claim 3, wherein the injector further comprises a long axis and the elongated slits are parallel to the long axis of the injector.
- 5. The turbogenerator system of claim 3, wherein the injector further comprises a long axis and elongated slits are at an angle to the long axis of the injector.
- 6. The turbogenerator system of claim 1, wherein the fuel and the compressed air are introduced into the combustor at generally constant fuel-to-air ratio over operating range of the turbine engine.
- 7. The turbogenerator system of claim 1, wherein the pressure actuator further comprises:
a spring.
- 8. The turbogenerator system of claim 7, wherein the pressure actuator further comprises:
a metal bellows.
- 9. The turbogenerator system of claim 7, wherein the spring is preloaded for maintaining a preselected entry for the compressed air at start of operation of the combustor.
- 10. The turbogenerator system of claim 1, wherein the combustor further comprises an inner liner and an outer liner, and further comprising:
one or more rows of air dilution holes in the inner liner.
- 11. The turbogenerator system of claim 10 further comprising:
one or more rows of air dilution holes in the outer liner.
