WIDE RANGE FUEL FLOW METER

OBJECTIVES OF THIS PROJECT ARE TO INVESTIGATE TWO INNOVATIIVE DESIGNS FOR TURBINE METERS HAVING AN ACCURACY OF 1% OR BETTER OVER A WIDE RANGE OF FLOW RATES, IN THE AREA OF 140 OR 1 OR BETTER. ANALYSES WILL BE PERFORMED TO DETERMINE THE EXPECTED PERFORMANCE CHARACTERISTICS OF EACH DESIGN, AND ONE DESIGN SELECTED FOR BREADBOARD DESIGN, FABRICATION AND TEST. DESIGNS TO BE STUDIED AND TESTED INCORPORATED NOVEL MEANS FOR OVERCOMING THE VARIOUS DRAG FORCES WHICH LIMIT LINEARITY, ACCURACY AND REPEATABILITY OF TURBINE METERS AT FLOW RATES BELOW THE NORMAL RANGE ACHIEVABLE WITH CONVENTIONAL DESIGNS. A WORKING MODEL WILL BE TESTED FOR ACCURACY, LINEARITY, REPEATABILITY AND RELIABILITY, WITH THE RESULTS EVALUATED FOR FUTURE IMPROVEMENTS AND DEVELOPMENT INTO A PRODUCT SUITED FOR USE BY THE GOVERNMENT AND PRIVATE JET ENGINE TESTING FACILITIES. SUCH A METER IS WIDELY NEEDED IN ORDER TO OBTAIN ACCURATE FLOW DATA OVER WIDE RANGES OF FLOW RATES DURING ENGINE ACCELERATION. SEVERAL SIGNIFICANT INDUSTRIAL APPLICATIONS ARE ALSO ANTICIPATED.
