Gulfstream American Gulfstream 2 (N20H)

Hubbard Broadcasting, Inc. Gulfstream American G-1159 Reg: N20H Cn: 51 N20H departs St. Paul with the Holman Field control tower in the background. The attached Hubbard Aviation Technologies' QS3 hushkit system brings the jet below Stage-III noise standard and consists of 3 main components: 1) an alternating-lobe exhaust nozzle which attenuates low-frequencies into higher frequencies; 2) a titanium-core ejector which absorbs the converted higher frequency noise; 3) new cascade-style thrust-reversers to accommodate the attached ejector.
