Summary of Systems Design Studies of Turbofan Powered Light Aircraft

The NASA sponsored studies of the potential of the turbofan engine for light aircraft have approached the total aircraft design and mission rather than the engine cycle and design alone. In addition, the commonality of military trainer and civil requirements have been addressed. It has been demonstrated that the proper choice of turbofan engines coupled with advanced wing and flap design will result in either a superior or comparable aircraft design for all classes of light aircraft. Improved noise and emission characteristics can be expected with comparable fuel consumption. Costs are a question mark, but high volume production techniques could result in marked reductions in turbofan engine costs.
