Abstract

A vehicle with a body, an engine, and an engine driven fan. The engine is connected to the body. The engine driven fan is mounted to the body for providing thrust capable of effecting controlled motion of the vehicle in at least one direction. The fan has a fan section drivingly connected to the engine. The fan section has fan blades. At least one of the fan blades has a tip jet and boundary layer control slot formed therein.

Claims

1. A vehicle comprising:

a body;

an engine connected to the body; and

an engine driven fan mounted to the body for providing thrust capable of effecting controlled motion of the vehicle in at least one direction, the fan comprising a fan section drivingly connected to the engine, wherein the fan section has fan blades, at least one of which has a tip jet and a boundary layer control slot formed therein.

2. The vehicle in accordance with claim 1, wherein the engine is an air breathing gas turbine engine.

3. The vehicle in accordance with claim 1, wherein the fan is a ducted fan.

4. The vehicle in accordance with claim 1, wherein the fan is an high-bypass ratio fan.

5. The vehicle in accordance with claim 1, wherein the boundary layer control slot is a spanwise oriented slot.

6. The vehicle in accordance with claim 1, wherein the fan blades are rotated by engine exhaust gas exhausting from the tip jet.

7. A vehicle comprising:

a body;

an engine connected to the body; and

an engine driven fan mounted to the body for providing thrust capable of effecting controlled motion of the vehicle in at least one direction, the fan having an active aspirated fan rotor with upper surface blowing, the fan rotor being operably coupled to the engine for engine exhaust gas to aspirate the fan rotor.

8. The vehicle in accordance with claim 7, wherein the fan rotor has differential blowing between different fan blades.

9. The vehicle in accordance with claim 8, wherein the differential blowing is between advancing and retreating blades.

10. The vehicle in accordance with claim 7, wherein the fan is a ducted fan.

11. The vehicle in accordance with claim 7, wherein the fan is located in a fan duct having an inlet with Coanda slot blowing.
