Thrust Reverser Design for Airframe Compatibility

THE thrust reverser is a powerplant component subject to equally fundamental demands by both the engine and airframe and as such represents an Airframe/Propulsion interface topic. Since it makes a significant contribution to DOC, primarily by its capital cost and weight which may typically be some 16% and 18% of a current fan engine powerplant respectively, there is a requirement to develop comprehensive criteria for safety, performance and cost effectiveness assessment. This requirement has always existed but has been submerged by the need to place effort on components which have yielded a more readily identifiable return. The need to economise on both financial and energy resources is resulting in closer attention to powerplant total compatibility and an increasing effort on reverser installation is required.
