Download or read book Heat and Thrust Requirements of a Thermal Fog Dispersal System written by Bruce A. Kunkel and published by . This book was released on 1975 with total page 48 pages. Available in PDF, EPUB and Kindle. Book excerpt: Field tests were conducted with a subscale momentum/heat system, to determine the optimum heat and thrust requirements and combustor positions for a full scale thermal fog dispersal system. The site, located in Irvine, California, was laid out on a 1/6 scale. The Froude number scaling law was used to scale up to full scale. An array of 65 thermistors and 6 wind sensors was located in the target area over a simulated runway. Wind and temperature sensors were also located outside of the target area to provide background measurements during the tests. Tests were conducted at night, in clear air, during calm conditions. Both momentum and passive heat systems are evaluated in terms of heat and thrust requirements for different wind conditions. A single line momentum/heat system requires 5 to 10 times as much thrust as does a two-side-of-the-runway system. A passive system requires anywhere from 130-470 percent more heat output than does a momentum system. The appropriate system for a particular airfield can only be determined after a cost analysis has been made of the various systems and a wind study has been made of the particular airfield.

Available in PDF, EPUB and Kindle. Book excerpt: An extensive investigation has been made to arrive at optimum specifications for a thermo-kinetic warm fog dispersal system. This study included passive heat tests, sub-scale heat/momentum tests, and tests with a single full-scale runway combustor and an approach zone combustor. These tests were augmented with extensive analytical modeling of buoyant jets under coflowing and counterflowing wind conditions. The landing category and the operational requirements within each category are the primary factors affecting the size of the thermal fog dispersal system (TFDS). A Cat 2 TFDS employs 22 percent fewer combustors and uses 50 percent less fuel than a Cat 1 TFDS. The combustor specification and orientation are presented for both Cat 1 and Cat 2 systems.

Book excerpt: Climatological records of fog occurrence and wind characteristics in fog are used to design a passive ground-based heat system for the dispersal of warm fog at Travis AFB, California. The array of heat sources is patterned after that described by FIDO engineers for parallel winds. The burner array shape is similar to an elongated horseshoe that encloses the upwind end of the runway, with the parallel legs 450 ft apart terminating 240 ft short of a 700-ft-long cross leg. An analysis of air traffic records in combination with fog statistics indicates that the system could be used to aid approximately 900 (2600) landings and takeoffs in an average (extreme) year during the fog-plagued months from November to February. Assuming a burn time of five minutes per landing or takeoff, the heaters could be expected to operate approximately 75 (260) h and consume approximately eleven (48) million gallons of fuel in an average (extreme) year. During the time the system is operating it generates heat at a rate of approximately 10 billion BTU/h. (Author).
