Photograph: In this view up the tailpipe of the G-II/G-III hush kit mockup, the lower internal deflector that redirects the exhaust into the cascade is visible in the deployed position. Note the 10-lobe mixer/ejector that does much of the job of hushing the noisy Spey. Stage III Technologies and Dallas Airmotive have tangible evidence of their hush treatment of the Rolls-Royce Spey turbofan in the form of a full-size detailed mockup mounted on the left nacelle of a Gulfstream II.

A proposed new, small turbine engine from Allison will look nothing at all like the engine builder's current--and ubiquitous--Model 250 turboshaft. While bracketing the same 350- to 800-shp power range, the powerplant will shun the Model 250's reverse-flow gas path for a more straightforward axial-flow configuration.

Leasing continues to be a popular vehicle for enjoying the benefits of business aircraft without the attendant tax exposure, and 1996 proved to be another growth year for the equipment leasing industry. New business volume was up, and lessors taking possession of aircraft at lease terminations experienced better-than-anticipated residuals due to a brisk resale market. One major lease/finance company claimed it increased its business aircraft portfolio by 20 percent.
