Description

ORGIN OF THE INVENTION

This invention was made by employees of the United States Government any may be manufactured and used by or for the Government of the United States of America for governmental purposes without the payment of any royalties thereon or therefor.

TECHNICAL FIELD

The present invention relates to an aircraft configured for flight in an atmosphere having a low density.

BACKGROUND OF THE INVENTION

The Mars atmosphere is thin and composed mostly of carbon dioxide. The gravity is lower than the gravity on Earth. More specifically, atmospheric density near the Martian surface is roughly equivalent to an altitude of 100,000 feet on Earth. The low atmospheric density leads to a high cruise velocity, but a low Reynolds number. Since the speed of sound on Mars is lower than on Earth, transonic aerodynamic effects are encountered at a lower flight speed. Low atmospheric density also presents difficulty in generating sufficient thrust. Therefore, with such a thin atmosphere, generating enough lift to support airplane weight is difficult and wing loading must be small.

In addition to the challenge of generating sufficient lift and thrust to fly an airplane through the Martian atmosphere, there are challenges associated with getting the airplane to Mars. These challenges include stowage of the airplane in a non-flight configuration and the extraction of the airplane from the non-flight configuration to an in-flight configuration capable of flight in a thin atmosphere.

SUMMARY OF THE INVENTION

An aircraft is configured for flight in an atmosphere having a low density. The aircraft includes a fuselage, a pair of wings, and a rear stabilizer. The pair of wings extends from the fuselage in opposition to one another. The rear stabilizer extends from the fuselage in spaced relationship to the pair of wings. The fuselage, the wings, and the rear stabilizer each present an upper surface opposing a lower surface. The upper and lower surfaces have X, Y, and Z coordinates that are configured for flight in an atmosphere having low density.

The above features and advantages and other features and advantages of the present invention are readily apparent from the following detailed description of the best modes for carrying out the invention when taken in connection with the accompanying drawings.

DESCRIPTION OF THE PREFERRED EMBODIMENTS

Referring to the drawings, wherein like reference numbers refer to like components, FIG. 1 shows an aircraft 10 configured for flight in an atmosphere having a low density. More specifically, the aircraft 10 includes a fuselage 12, a pair of wings 14, and a rear stabilizer 16. A stabilizer bar 18 operatively interconnects the fuselage 12 and the rear stabilizer 16.

The aircraft 10 is configured to move between an unfolded position 20, as shown in FIG. 1A, and a folded position 22, as shown in FIG. 1B, and vice versa. When the aircraft 10 is in the folded position 22, the aircraft 10 is configured to fit within volumetric space limitations of an aeroshell 24 (or similar capsule) of a launch vehicle, i.e., a Delta II, and the like (not shown). More specifically, the aircraft 10 is configured to move between the folded position 22 and the unfolded position 20 with only three folds 26a, 26b, 26c. Two of the folds 26a, 26b are on a respective wing 14 and the third fold 26c is on the stabilizer bar 18. Therefore, each of the wings 14 is foldable, relative to the fuselage 12, along the fold 26a, 26b, i.e., a wing hinge. Likewise, the rear stabilizer 16 is foldable, relative to the fuselage 12, along the fold 26c, i.e., a stabilizer hinge. It should be appreciated, however, that the aircraft 10 may be configured with any other desired number of folds, as known to those skilled in the art.

The aircraft 10 is also configured to have a desired mass and mass distribution when in the folded position 22 such that the aircraft 10 is transported stably within the launch vehicle. Likewise, the aircraft 10 is configured such that the mass and mass distribution provides stability in the unfolded position 20, for flight, without any artificial augmentation. A structural arrangement, i.e., internally and externally, is configured such that the aircraft 10 survives loads associated with launch and reentry (Earth and Mars, Earth and Earth, respectively). The aircraft 10 is also configured with a desired propulsion system duration, power, and efficiency to provide required speed and endurance. Additionally, the aircraft 10 is configured to have adequate payload capacity in both volume and mass available, while allowing any required subsystems to exist, e.g., batteries, guidance, control, telemetry, etc.

When the airplane is stowed in the launch vehicle in the folded position 22 within the confined volume, the airplane is configured to be transported via flight, e.g., via a rocket and the like, and released from the confined volume during flight. When the aircraft 10 is released from the confined volume of the launch vehicle during flight, the aircraft 10 is configured such that the wings 14 and the rear stabilizer 16 unfold about the respective folds. Once the aircraft 10 is in the unfolded position 20, the aircraft 10 is configured for controlled flight in low density, such as around Mars. It should be appreciated, however, that the aircraft 10 is not limited to flight around Mars as the aircraft 10 is configured for flight in any planetary atmosphere with a low density.

Referring to FIGS. 1A-5, the fuselage 12, the pair of wings 14, and the rear stabilizer 16 present an upper surface 28 opposing a lower surface 30. The geometry of the upper and lower surfaces 28, 30 provides the requisite aerodynamic properties to the aircraft 10, such as lift and drag, such that flight in low density can be achieved. The upper and lower surfaces 28, 30 are defined at X, Y, and Z locations in a 3-dimensional X, Y, Z configuration. The X positions are defined along an X axis that generally extends between the wings 14. The Y locations are defined along a Y axis that extends along the fuselage 12, in perpendicular relationship to the x-axis. The Z locations are defined along a Z axis that generally extends in perpendicular relationship to the X axis and the Y axis. The upper and lower surfaces 28, 30 are defined at Y and Z positions corresponding substantially to an X position of 120.0, as shown in Table 1 and at 100 in FIG. 6.
