This report presents the preliminary design and cost analysis of a low cost jet fuel starter. This unit is an accessory to be used for starting main aircraft propulsion units, and requires only jet fuel and battery power to achieve safe reliable starts. The basic starter has a peak output of 150 horsepower, is 10.0 inches in diameter, 20 inches long and weighs 98 pounds. The starter is capable of operating over an ambient temperature range of -65F to 130F and at altitudes up to 8,000 feet. The design features a radial air inlet, axial exhaust, and a low speed concentric shaft, with front power output. The low speed low stress permits simple construction and low cost fabrication techniques with an overall reduction in total parts and cost when compared with typical high speed units. The cost analysis indicates that the starter selling price is less than 8,000 per unit in quantities of 100 per year, including tooling and R and D costs amortized over 2500 units.
