Unmanned aircraft external pressure determination unit has static pressure sensor recessed into hole in aircraft

摘要

#CMT# #/CMT# An unmanned aircraft (F) external pressure determination unit has a computer (10) connected static pressure sensor (1) recessed into a hole in the aircraft on the opposite side to the flow where (5) the flow can become detached or a pitot sensor in an engine inlet and linked to a base station to check the flight altitude. #CMT# : #/CMT# Independent claims are included for aircraft using the system. #CMT#USE : #/CMT# External pressure determination unit for military aircraft and drones. #CMT#ADVANTAGE : #/CMT# Fitting the pressure measurement openings in a recess or engine inlet reduces reflection of radar waves. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows and unmanned aircraft with the static pressure sensor type. 1 : Static pressure sensor 5 : Detached flow region 12 : Signal lead 10 : Computer 20 : Autopilot 30 : Transponder 40 : Base station.
