Relating Technology to Acquisition Costs. Aircraft Turbine Engines,
Abstract
The quantitative measure presented in the report is derived from a recent Rand study in which a technique was developed for assessing the date at which an aircraft turbine engine with a specified set of technical parameters should pass its 150-hr Model Qualification Test (MQT). The refined aircraft turbine engine TOA model is based on 26 U.S. military turbojet and turbofan engines developed and produced during the past 30 years. The model predicts the man-rated 150-hr MQT date as a function of certain of the engine's performance and design parameters. The parameters include maximum thrust of the engine at sea-level static conditions, weight, specific fuel consumption at military thrust at sea-level static, turbine inlet temperature, and a pressure term (the product of flight envelope maximum dynamic pressure and the overall pressure ratio of the engine).
