Abstract
The Duffel Bag Airplane is an inflatable flying wing unmanned airborne vehicle (UAV). The fuselage will house everything but the wings. The wing can be rolled up around the fuselage into a small package when deflated for easy transportation, such as by being carried in a duffle bag. Fabric construction, a small internal combustion engine with cooled exhaust, and wing warping controls combine to make the airplane inexpensive and extremely stealthy. All the usual signatures have been suppressed, which allow it to be used to make observations from close range under combat conditions. Control of this airplane is accomplished by warping the wings and is supplemented with stability augmentation.
Claims21
A portable, stealthy airplane comprising:
- an inflatable wing deployable in a deflated condition for storage and in an inflated condition for use;
- an engine for propelling the airplane;
- and
- a blower powered by the engine for moving a flow of air for cooling an exhaust stream produced by the engine prior to the exhaust stream being released from the airplane.
An airplane comprising:
- an internal combustion engine producing a hot exhaust stream;
- a means for cooling the hot exhaust stream prior to its release from the airplane;
- a wing;
- a first chamber formed in the wing for retaining a compressed gas for providing a desired degree of structural rigidity to the wing;
- and
- a second chamber formed in the wing for receiving the cooled exhaust stream and for directing the cooled exhaust stream to an outlet disposed proximate a trailing edge of the wing.
An airplane comprising:
- an inflatable wing deployable in a deflated condition for storage and in an inflated condition for use;
- an engine for propelling the airplane;
- an on-board compressor powered by the engine for inflating the wing for use;
- and
- an on-board blower for dispersing a flow of cooled engine exhaust prior to the discharge of the exhaust from the airplane.
A stealthy airplane comprising:
- an airfoil for providing lift;
- an engine for providing motive force and producing hot exhaust;
- and
- a blower for producing a flow of cooling air for mixing with the hot exhaust to produce cooled exhaust for exiting the airplane further comprising a plenum formed in the airfoil for directing the cooled exhaust to an outlet disposed proximate a trailing edge of the airfoil.
