The memorandum presents equations for estimating development and production costs of turbojet and turbofan engines. Thrust is found to be the best single variable for estimating both development and production cost, but using thrust alone the differences between actual and estimated costs are unacceptably large. For development, these differences are greatly reduced by incorporating a second explanatory variable--either speed, absolute altitude, or thrust-to-airflow ratio. (Author)
