Truncated pyramid-shape multi-hole pitot probe and flight velocity detection system using said truncated pyramid-shape multi-hole pitot probe

摘要: A flight velocity detection system using a truncated pyramid-shape multi-e Pitot probe in which an extreme end portion has pyramid-shape, cylindrical hole is provided at the apex thereof, total pressure tube of smaller diameter than that secured position by predetermined length determined relationship with from hole, and groups holes comprised plurality are arranged each pyramid surfaces shape. Items information detected input into vector processor to convert them electric signals, signals processed coefficients respect stored advance calculate (V, α, β) axis air density.
