Abstract
An aerial vehicle including a main body having a leading edge. An inlet is recessed aft from the leading edge. Forward protrusions extend from the main body on opposite sides of the inlet. An outlet nozzle is proximate to an aft end. The inlet is in fluid communication with the outlet nozzle. Wings extend from the main body.
Claims21
An aerial vehicle comprising:
- a main body having a leading edge,
- an inlet recessed aft from the leading edge;
- forward protrusions extending from the main body on opposite sides of the inlet;
- an outlet nozzle proximate to an aft end of the main body, wherein the inlet is in fluid communication with the outlet nozzle;
- wings extending from the aft end of the main body;
- and
- canards extending from a fore end of the main body.
4 more elements
A method of forming an aerial vehicle, the method comprising:
- recessing an inlet aft from a leading edge of a main body;
- extending forward protrusions from the main body on opposite sides of the inlet;
- extending canards from a fore end of the main body;
- fluidly coupling an outlet nozzle proximate to an aft end of the main body to the inlet;
- and
- extending wings from the aft end of the main body.
3 more elements
An unmanned aerial vehicle (UAV) comprising:
- a main body having a leading edge, wherein the main body comprises a base having a flat forward upper surface;
- an inlet recessed aft from the leading edge a distance that is between 1 to 5 times a height of the inlet, wherein an aspect ratio is defined as a ratio of a width to the height of the inlet, and wherein the aspect ratio is between 3 and 7;
- forward protrusions extending from the main body on opposite sides of the inlet, wherein at least one of the forward protrusions extends either above or below the height of the inlet, and wherein the forward protrusions form an entrance to the inlet;
- an outlet nozzle proximate to an aft end of the main body, wherein the inlet is in fluid communication with the outlet nozzle;
- wings extending from the aft end of the main body;
- and
- canards extending from a fore end of the main body, wherein at least portions of the canards extend to a plane that is aft of the inlet.
4 more elements
An aerial vehicle comprising:
- a main body having a leading edge,
- an inlet recessed aft from the leading edge;
- forward protrusions extending from the main body on opposite sides of the inlet, wherein at least one of the forward protrusions extends either above or below a height of the inlet;
- an outlet nozzle proximate to an aft end of the main body, wherein the inlet is in fluid communication with the outlet nozzle;
- and
- wings extending from the main body.
3 more elements
An aerial vehicle comprising:
- a main body having a leading edge,
- an inlet recessed aft from the leading edge;
