Its Grumman model number is G-1159 and its US military designation is C-11 Gulfstream II.1 Military operators o 4. 1966. seen here taxiing at Mojave The Gulfstream II (G-II) is an American twin engine business jet designed and built by Grumman and then in succession.[1] Contents  1 Design  2 Variants  3 Special mission variants  4 Operators o 4. It has been succeeded by the Gulfstream III. attention was paid to the aircraft's low speed requirements by tailoring the leading edge radius to preclude leading edge separation.[2] During installation of the Aviation Partners Inc. particularly at large flap deflections. the FAA modified 14 CFR part 91 rules to prohibit the operation of jets weighing 75. The aft-mounted engine location was selected after extensive analysis and design iterations considering aerodynamic.[2] The high angle of attack investigations on the Gulfstream II indicated that stable trim conditions existed up to 45 degrees angle of attack. structural. Stall initiation on the basic wing was found to occur at midspan but spread rapidly to the tip. and other operational advantages of its predecessor. The addition of an upper surface fence at about midspan provided a strong pitch down at the stall. and also afforded an adequate margin between initial and tip stall. Rather than pursue a lengthy flight test research effort. The Gulfstream II is listed explicitly in Federal Register 78 FR 39576. In developing the wing contours. The interference problem at the wingbody juncture was treated by modification of the airfoil shape and thickness over the inner third of the wing span.[3] In 2013. and ground clearance requirements. single-slotted Fowler flap of 30% chord. the vortex generators and midspan fence were removed and replaced with six leading edge vortilons similar to those found on the Gulfstream IV. Any Gulfstream II's that . reliability. The high lift configuration.85 speed capability was attained by incorporating a row of co-rotating vortex generators on the outer wing panel. The elevator deflection required to trim to the primary stall at most forward center of gravity was sufficient to trim a deep stall at the aft center of gravity. Airfoil geometry was developed to maximum sweep benefit from the selected planform. A buffet boundary commensurate with the M=. Configuration buildup studies revealed the adverse nacelle influence on tail pitching moment contribution above 30 degrees angle of attack was not unduly severe and no appreciable effect on elevator or stabilizer effectiveness was found. without sacrificing maximum lift. 2015. The basic airfoils for the main area of the wing are similar to those of the Grumman A-6 Intruder aircraft and utilize NACA 6-series thickness distributions combined with an in-house mean line.[2] It was found in flight testing that the stall characteristics were satisfactory but did not preclude stall penetrations to the point of secondary stall pitchup. but recovery from deep stall was immediate upon forward stick motion. it was decided to mechanically limit the extent of stall penetration with a stick shaker and stick pusher. winglets (as the G-IISP). and in view of the excellent primary stall behavior. the turboprop Gulfstream I. Preliminary design of the wing was influenced by both cruise and low speed considerations.Design The Gulfstream II is a twin-jet swept wing corporate transport designed to provide high speed and long range capability without sacrificing the airport performance. and more than adequate nose-down elevator control was available.000 pounds or less that are not stage 3 noise compliant after December 31. The acceptability of the Gulfstream II high angle of attack characteristics and the absence of a deep stall influence on configuration sizing and arrangement was attributed to the mitigating influence of the nacelle-wing overlap on nacelle contribution. consists of a one piece. so configured. powering a 9-foot diameter Hamilton Standard SR-7 propfan.
