Abstract

The aircraft comprises a main wing, also functioning as a fuselage, and supported between two side panels, which may house fuel tanks and the undercarriage. Efflux from two jet engines may enter respective diverter chambers, each having a rear outlet for generating forward thrust and controlled by a flap, and downward directed outlets for generating lift when the rear outlet is closed by the flap. Additional jets for producing forward thrust may also be provided. A secondary wing may be provided beneath the main wing.

Description

2354502 FLYING VvqNG AND JETLIFT This invention relates to aircraft and in

particular to Short Takeoff and Landing. (STOL)

The present generation of jet aircraft need a very long runway in order to take off and land. This because the wings of the aircraft need high speed airflow to enable the aircraft to fly, the wings being the lifting device. On landing a relatively high speed must also be maintained for the same reason. This consideration means that aircraft are limited to airfields having the necessary length for operational purposes. The high speed attained on takeoff and landing also pose a constant threat to safety.

According to the present invention the separate fuselage is not necessary as the wing has the dual function of wing and fuselage. The jet engines also have a dual finiction providing both lift and thrust.

A specific embodiment of the invention will now be described by way of example with reference to the accompanying drawings 1, 2 & 3 in which: Figure I shows a front view of the wing/fuselage and the side panels that act as support for the wing/fuselage and jet engines. Also shown in this view is a secondary wing for additional lift. There are additional jets for forward thrust to the outside of the side panels. These side panels may be used to house the undercarriage and for fuel tanks. The secondary wing may also be used for fuel tanks.

Figure 2 shows a side view of the Flying Wing and Jetlift. This view shows the combined wing and fuselage, There is sufficient space below the wing/fuselage to ensure efficient airflow over the wing/fuselage for effective lift.

Figure 3 show an under-view of the Flying Wing and Jetlift. It can be seen that a jet engine is sealed into the front of a diverter chamber to discharge jet efflux into this chamber. The diverter chamber has an efflux escape flap at the rear that can fully or partially seal the chamber. The diverter chamber also has downward looking outlets that may be slots as shown or shaped holes. In operation with the efflux escape flap in closed position B jet efflux is directed downwards and provides dedicated lift thus lightening the aircraft. With the efflux escape flap in open position A jet efflux is directed to the rear thus providing dedicated thrust.

This combination of downward directed jet efflux and the expanse of the wing/fuselage gives a combination that in operation allows a slow take off and landing in a short distance.
