Abstract
By manipulating the fluid flow in the proximity of an object such as a fuselage, a wing, or the hull of ship, the wave drag associated with this object can be substantially reduced. This can be accomplished by locally changing both the fluid flow velocity and the pressure of the fluid flow.
Claims55
A system for reducing wave drag, the system comprising:
- an outer surface configured for receiving exterior fluid flow of a fluid;
- a channel coupled to the outer surface and configured for receiving an interior fluid flow of the fluid, the channel including a fluid inlet and a fluid outlet, the channel being configured to manipulate the interior fluid flow to reduce wave drag;
- wherein the channel comprises:
- a first fluid manipulation apparatus (“FMA”) configured to receive the interior fluid flow downstream of the fluid inlet and further configured to change speed and pressure of the fluid flow within the channel;
- a pressure containment apparatus (“PCA”) configured to receive the interior fluid flow downstream of the first FMA;
- and
- a second FMA configured to receive the interior fluid flow downstream of the PCA and upstream of the fluid outlet, the second FMA being configured to further change the speed and pressure of the interior fluid flow,
- wherein the free stream has a free stream velocity that is greater than a wave velocity of a wave within the free stream.
A method of reducing the wave drag of a vehicle, the method comprising:
- providing a first fluid manipulation apparatus (“FMA”);
- providing a second FMA at least partially within the downstream streamtube of the first FMA;
- and
- providing a pressure containment apparatus (“PCA”) configured to at least partially enclose a streamtube passing through both the first and the second FMA.
The method of claim 58, wherein the fluid is compressible, and wherein the first FMA is configured to decelerate and increase the pressure of the fluid, and wherein the second FMA is configured to accelerate and decrease the pressure of the fluid, and wherein the method further comprises providing a wing within the PCA such that lift is generated in a lower speed, higher pressure flow regime compared to the free stream flow.
The method of claim 58, wherein the fluid is incompressible, and wherein the first FMA is configured to accelerate and decrease the pressure of the fluid, and wherein the second FMA is configured to decelerate and increase the pressure of the fluid, and wherein the method further comprises transporting the lower pressure and lower cross-sectional area flow via the PCA through a vehicle from the first FMA to the second FMA such that less wave drag is generated by the vehicle.
