FIELD: device for measurement of helicopter altitude-speed parameters. ^ SUBSTANCE: the system has a flow-through multichannel aerometric receiver, throttled static pressure chambers and whose 2n impact pressure pipes are commented to the inputs of n differential pneumoelectric converters, where n=2.3... , whose electric measuring circuits via series-connected multiplexer and analog-to-digital converter are connected to a microprocessor, whose output servers as the output of the system of the helicopter altitude-speed flight parameters. Differential thermo anemometric gas-flow transducers may be used as pneumoelectric converters. ^ EFFECT: simplified embodiment of the system. ^ 2 cl, 3 dwg |
