An inlet for an aircraft, missile or other high speed airborne mobile platform, to receive intake air and compress the intake air for delivery to an engine of the mobile platform. The inlet has an array of inlet elements placed in side-by-side arrangement. Each inlet element has a passage for delivery of intake air. The array provides for compact volume and effective aerodynamic performance. The inlet may be mounted for rotation to start the inlet when at a supersonic speed. The inlet is shorter in length than traditional inlets and can be integrated into a wider variety of airframes, or at locations on existing airframes that would be difficult or impossible to integrate a traditional inlet on.

What is claimed is: 1. An inlet for an supersonic airborne mobile platform to receive intake air at a supersonic speed and to compress the intake air for delivery to an engine of the mobile platform while the mobile platform is travelling at a supersonic speed, the inlet comprising: a plurality of inlet elements placed in side-by-side arrangement defining an array, each said inlet element having a passage for delivery of intake air at a supersonic speed, said array including two or more of said inlet elements forming a row and two or more of said inlet elements forming a column; each said inlet element having a forward end, a rearward end, and a flow area along the passage which is non-uniform between the forward end and the rearward end, and which forms a reduced area region at an intermediate point between its forward and rearward ends for compressing said intake air as it flows therethrough. 2. The inlet as set forth in claim 1, wherein all of the inlet elements of the array are placed in a contiguous arrangement. 3. The inlet as set forth in claim 2, wherein the forward end of each said inlet element has an edge which is coterminous with an adjacent one of said inlet elements. 4. The inlet as set forth in claim 2, wherein the passages of all of said inlet elements in said array are generally parallel. 5. The inlet as set forth in claim 4, wherein all the passages of said plurality of inlet elements are substantially identical. 6. The inlet as set forth in claim 5, wherein said row and said column of the array are arranged in a generally perpendicular relation. 7. The inlet as set forth in claim 1, wherein said row extends in a first direction and said column extends in a second direction which is non-collinear with said first direction. 8. The inlet as set forth in claim 1, wherein the forward ends of said plurality of inlet elements collectively define a front face of the inlet, and wherein said front face is generally planar. 9. The inlet as set forth in claim 1, wherein the forward ends of said plurality of inlet elements collectively define a front face of the inlet, and wherein said front face is generally conical. 10. The inlet as set forth in claim 1, wherein the reduced area region is formed at an intermediate point along the length of the passage. 11. The inlet as set forth in claim 1, wherein the passage of each said inlet element includes side walls which have a caret shape. 12. The inlet as set forth in claim 1, wherein the passage of each said inlet element has exactly four side walls. 13. The inlet as set forth in claim 1, wherein the passage of each said inlet element has exactly three side walls. 14. The inlet as set forth in claim 1, wherein the passage of each said inlet element has exactly six side walls. 15. The inlet as set forth in claim 1, wherein the inlet has a one-piece construction. 16. The inlet as set forth in claim 1, in combination with said mobile platform. 17. The inlet as set forth in claim 16, wherein the inlet is pivotally moveable relative to the mobile platform. 18. The inlet as set forth in claim 16, wherein the mobile platform has a forward directional axis and a vertical axis, the forward ends of said plurality of inlet elements collectively define a front face of the inlet which is generally planar, and wherein the front face of the inlet is oriented at an oblique angle with respect to the forward direction and at an oblique angle with respect to the vertical direction. 19. An inlet for an supersonic airborne mobile platform to receive intake air at a supersonic speed and to compress the intake air for delivery to an engine of the mobile platform while the mobile platform is travelling at a supersonic speed, the inlet comprising: a plurality of inlet elements placed in side-by-side arrangement defining an integral array, each said inlet element having a passage for delivery of intake air at a supersonic speed, said array including two or more of said inlet elements forming a row and two or more of said inlet elements forming a column; each said inlet element having a forward end, a rearward end, and a curving, cross sectional flow area along the passage which is non-uniform in area between the forward end and the rearward end.
