Abstract
A pitot-static array system for a tail-sitting aircraft has a disk with a plurality of edge ports arrayed about an edge of the disk. Each of a plurality of pressure transducers is configured to measure air pressure at one of the edge ports. The edge ports are arrayed about an axis parallel to a pitch axis of the aircraft.
Claims23
A pitot-static array system for a tail-sitting aircraft, the pitot-static array system comprising:
- a disk having a plurality of edge ports arrayed about an edge of the disk;
- and
- a plurality of pressure transducers, each transducer configured to measure air pressure at one of the edge ports;
- wherein the edge ports are arrayed about an axis parallel to a pitch axis of the aircraft;
- and
- wherein at least one of the edge ports is used as a ram pressure port;
- wherein at least one of the edge ports is used as a static pressure port.

A pitot-static array system, comprising:
- a disk having;
- an array of edge ports aligned on an edge surface of the disk;
- and
- a side port located on a circular surface of the disk;
- and
- a plurality of pressure transducers configured to measure a ram air pressure of each edge port and a static air pressure of the side port;
- wherein each port is in fluid communication with one of the pressure transducers.
(canceled)
A pitot-static array system for an aircraft, the pitot-static array system comprising:
- a disk having a plurality of edge ports arrayed about an edge of the disk;
- a side port located on a side surface of the disk;
- a plurality of pressure transducers, one of the plurality of transducers being configured to measure ram air pressure at each of the edge ports, and one of the plurality of transducers being configured to measure static air pressure at the side port;
- wherein the edge ports are arrayed about an axis parallel to a pitch axis of the aircraft, and the side port is oriented as parallel to the pitch axis.
