Munition Expenditure Model Verification: KWIK. Phase I.
Abstract
A munition expenditure model is developed called KWIK (a mnemonic derived from crosswind integrated concentration), which uses Gaussian diffusion theory. Phase I of the KWIK Munition Expenditure Model verification test was conducted for visible wavelengths, using statically detonated hexacholorethane (HC) smoke sources. Results presented show a mean smoke screening effectiveness of 88 percent and 99 percent of the screen duration time, for low (< 7 knots) and moderate (7 to 15 knots) windspeeds, respectively. Under satisfactory screening conditions, the KWIK model predicted 5 percent fewer munitions than the Field Manual (FM) method for the low relative humidity (RH about 30.5 percent) during the test. Thirty-eight percent fewer rounds would have been used by the KWIK model had high relative humidity (RH about 80 percent) occurred during this test. Eight trials, conducted under conditions considered unfavorable by the FM method (winds > 16 knots), produced a 100 percent mean effectiveness in screening the targets. Phase I results also indicate that use of target area meteorology is desirable under low windspeeds or marginal screening conditions, but may not be necessary under high windspeeds resulting from synoptic scale weather systems.
