A five-hole spherical pitot-tube produced for experimental purposes has been tested for measuring such air-data as velocity, angle of attack, sideslip angle and static-pressure of aircraft. There are few cases in measuring the static-pressure by five-hole spherical pitot-tube, although the measurements of air-speed, angle of attack and sideslip-angle are well known. Since the five-hole spherical pitot-tube is normally installed at a position far from the lifting surface, one can expect to measure the static-pressure without position-error. At first, wind-tunnel tests of the five-hole spherical pitot-tube were conducted. The presure on the surface of the sphere was different from that estimated by theory. Such a difference between theory and practice induced considerable adverse effects on the accuracy of the measured air-data. So, by using new revised equations based on the results of the wind-tunnel tests, we were able to estimate all the air-data with much more accuracy. Next, we made some flight-tests in order to ascertain position-error in free static-pressure measurements. The tests were performed under such conditions as level-flight, steady-turn, landing and take-off during the experiments. The static-pressure measured by the five-hole spherical pitot-tube agreed well with measurements taken with a swivel-pitot and the resulting air-speed has been shown to be almost the same as that obtained from the position-error correction chart, which was made by the speed-course method. |
