Abstract:

A portable measuring device has been developed for assessment of cockpitcabin environmental parameters during flight. The apparatus can be employed in a medium-sized aluminum suitcase as a single self-contained unit, or subunits and sensors can be deployed about the aircraft cockpitcabin as conditions permit. For confined cockpits, a seatpack is used to contain subunits. The sensors include a hot-wire anemometer sensitive from 0 to 400 ftmin, a dew point hygrometer of range -40 to 50 C, an ambient temperature probe 0 to 100 C, and an absolute pressure transducer 0 to 800 mmHg. The output from each is linearized by internal circuitry and processed for both immediate digital display and simultaneous storage, together with time-code and voice record, on magnetic tape. The systems small size and flexible configuration permit derivation of mission-specific environmental profiles for aircraft ranging in size from single-place fighters to larger transport aircraft. Results obtained are useful in both the establishment of life support equipment design criteria and assessment of the physiological stresses of flight. Author
