A high response air angle probe to measure a flow direction in an air flow near or above Mach one. The probe is rotatably secured within an assembly with marking to indicate when a desired position of the probe within the air flow has been found. The probe includes a row of three high response pressure transducers on a leading edge region to detect when the probe is at a certain position within the air flow.

A card seal with an annular arrangement of cards that form the card seal, where the cards are interweaved and staggered to increase a sealing capability of the cards. The card seal is formed from leading edge cards staggered with trailing edge cards, and the cards have a thicker outer end and a thinner inner end where the interweaving occurs. Because of the varying thickness of the staggered cards, each card has a taper on the lower outer end that decreases from a high to a low on the inner side in order that a foot print for the card is constant across the bottom surface that floats on the rotating part.

Card seal for a turbine

A card seal with an annular arrangement of cards that form the card seal, where the cards each form an L-shape cross section with a wide front face and a narrow side face, where the side face has a constant width from a top end to a location greater than a mid-point, and from this point decreases in width to zero width at the bottom end. The side faces form a blockage against leakage flowing between adjacent cards in a cards seal assembly.
