## Abstract

This instant invention provides an airplane design mainly to eject rearward the high-speed exhaust gas from the engine of the airplane to flow through the upper surface of the wing, such that the forward propulsion forcing can be obtained via rearward ejecting the high-speed exhaust gas to push the air rearward, and also larger uplift forcing induced by a larger velocity difference vertically across the wing can be obtained to ascend the airplane at the same time. This velocity difference is generated because the air over the wing is accelerated by the ejected high-speed exhaust gas, but the air below the wing stays the same velocity, such that a bigger velocity difference is directly produced vertically across the wing, and thus more uplift forcing can be provided to ascend the airplane.

## Claims

### Claim 1

An airplane, comprising:
a main body;
a pair of original wings attached on the main body; and
a jet engine located at a lower front belly portion of the main body ahead of the original wings, wherein the jet engine is a built-in type and blows exhaust gas from the original wings;
a pair of longitudinal wings with a chord length greater than a span length, wherein each of the longitudinal wings is attached to and extends from a trailing edge of one of the original wings; and
a plurality of nozzles located at each original wing to eject the exhaust gas directly toward the longitudinal wings for providing an uplift force induced by a greater air velocity above the pair of longitudinal wings than below the longitudinal wings.

### Claim 2 (depends on 1)

The airplane according to claim 1, further comprising:
a guide pipe for leading the exhaust gas from the jet engine to an upper portion of each original wing;
wherein the guide pipe is furnished with a plurality of nozzles for receiving the exhaust gas from the jet engine, and a size of each nozzle decreases as a distance of the nozzle from the jet engine increases.

### Claim 3 (depends on 2)

The airplane according to claim 2, wherein the plurality of nozzles and the guide pipe are located at a front portion of the original wings to eject the exhaust gas above the original wings and the longitudinal wings.

### Claim 4 (depends on 1)

The airplane according to claim 1, wherein the plurality of nozzles is located at a rear portion of each original wing to eject the exhaust gas directly toward the longitudinal wings.

### Claim 5 (depends on 4)

The airplane according to claim 4, where each of the pair of original wings connects to one of the longitudinal wings for enlarging an area above the original wings for passing the exhaust gas.

### Claim 6 (depends on 1)

The airplane according to claim 1, further comprising:
a pair of transverse wings, wherein each of the transverse wings corresponds to one of the longitudinal wings; and
wherein the plurality of nozzles are located at a front portion of each original wing to eject the exhaust gas to the transverse wings and the longitudinal wings.

### Claim 7 (depends on 6)

The airplane according to claim 6, wherein each longitudinal wing connects one of the original wings to one of the transverse wings.

### Claim 8 (depends on 1)

The airplane according to claim 1, further comprising:
an intake grille for filtering and removing foreign objects furnished to the engine; and
a foreign-object wiper moving along upper and lower tracks over the grille in an outward direction for wiping out foreign objects.

### Claim 9 (depends on 8)

The airplane according to claim 8, wherein an outer frame of the intake grille is oval, the upper and lower tracks are not parallel to each other, and the foreign-object wiper has a clear rod with a variable length to slide along the two tracks.

### Claim 10 (depends on 9)

The airplane according to claim 9, wherein the clear rod consists of two rods telescoped together and connected by a spring, while a distance between the two tracks becomes wider, the spring is elongated to extend the clear rod, and while the distance between the two tracks becomes narrower, the spring is depressed to shorten the clear rod.

### Claim 11

An airplane, comprising:
a main body; a pair of wings attached on the main body;
a jet engine located at a lower front belly portion of the main body ahead of the wings, wherein the jet engine is a built-in type;
a guide pipe for leading exhaust gas ejected from the jet engine to an upper portion of each wing;
an intake grille for filtering and removing foreign objects furnished to the engine; and
a foreign-object wiper moving along upper and lower tracks over the grille in an outward direction for wiping out foreign objects;
wherein the guide pipe is furnished with a plurality of nozzles for receiving the exhaust gas from the engine, and a size of each nozzle decreases as a distance of the nozzle from the engine increases.

### Claim 12

A method for providing a lifting force for an airplane with a main body and a pair of original wings, comprising:
positioning a jet engine at a lower front belly portion of the main body ahead of the original wings, wherein the jet engine is a built-in type and blows exhaust gas from the original wings;
providing a pair of longitudinal wings, wherein each of the longitudinal wings is attached to and extends from a trailing edge of corresponding to one of the original wings; and
providing a plurality of nozzles located at each original wing to eject the exhaust gas directly toward the longitudinal wings for providing an uplift force induced by a greater air velocity above the pair of longitudinal wings than below the longitudinal wings;
providing a pair of transverse wings, wherein each of the transverse wings corresponds to one of the longitudinal wings; and
positioning the plurality of nozzles at a front portion of each original wing to eject the exhaust gas to the transverse wings and the longitudinal wings.

### Claim 13 (depends on 12)

The method according to claim 12, further comprising:
positioning the plurality of nozzles at a rear portion of each original wing to eject the exhaust gas directly toward the longitudinal wings.

### Claim 14 (depends on 12)

The method according to claim 12, further comprising:
filtering and removing foreign objects furnished to the jet engine with an intake grille; and
wiping out foreign objects by moving a foreign-object wiper along upper and lower tracks over the grille in an outward direction.

### Claim 15 (depends on 12)

The method according to claim 12, wherein each longitudinal wing connects one of the original wings to one of the transverse wings.

### Claim 16 (depends on 12)

The method according to claim 12, further comprising:
providing a guide pipe for leading the exhaust gas from the jet engine to an upper portion of each original wing;
wherein the guide pipe is furnished with a plurality of nozzles for receiving the exhaust gas from the engine, and a size of each nozzle decreases as a distance of the nozzle from the engine increases.

### Claim 17 (depends on 16)
