Abstract

Spacing wind machine-heater units close enough together to allow an overlapping effect offers more efficient frost protection than is possible with single isolated installations. A spacing interval of 300 feet is probably the optimum for most conditions, according to last year's tests with nine ground-level revolving units, producing 60 pounds thrust and burning 20 gallons of diesel fuel per hour.
