Research abstract
THE STUDY OF THE EFFECT OF HEAVY RAIN ON AIRCRAFT GENERAL PERFORMANCE REQUIRES KNOWLEDGE OF THE SIZE, VELOCITY, AND CONCENTRATION OF THE RAIN DROPS AFFECTING THE AIRCRAFT. THE PROGRAM WILL DEVELOP AND DEMONSTRATE A TECHNIQUE THAT WILL BE USED TO OBTAIN SUCH DATA. THE TECHNIQUE BASES THE MEASUREMENT ON THE LIGHT SCATTERED BY THE DROPLETS AND WILL BE ABLE TO OBTAIN NON-INTRUSIVELY AND IN REAL TIME VELOCITY AND SIZE DISTRIBUTIONS OF THE DROPLET POPULATION. A SIZE RANGE OF 0.1 MM TO 5 MM WILL BE POSSIBLE WITH THIS TECHNIQUE. LIMITATIONS RESULTING FROM HEAVY RAIN LOADS WILL BE ESTABLISHED AND PRACTICAL SIZE AND VELOCITY RANGES WILL BE ESTIMATED FOR A GIVEN OPTICAL CONFIGURATION.
