The Gulfstream G-550 is a long-range business/executive jet powered by two Rolls-Royce BR710 turbofan engines. It has advanced cockpit avionics (see Figure 1.1) and a variety of seating configurations. The G-550 is a transport-type airplane, certified for day and night, extended over-water and polar navigation. A few examples of calculations are shown throughout the book (see, for example, the SAR analysis in §12.3.1 and the payload-range in § 15.2).

A summary of weights, capacity and limitations is given in TableA.1.Asummary of geometrical dimensions is given in TableA.2. The wing is swept back 27 degrees at the quarter-chord location, with a 3-degree dihedral, and with a tip-mounted upper winglet. The wing does not have a leading-edge slat. The main flight controls are a single Fowler-type flap, ailerons and trim tabs. There are three spoilers per side. There are some drag-reduction devices, such as vortex generators that wrap around the winglet junction, vortex generators on the upper side of the wing and blunt trailing edges. Furthermore, there are seals installed around rudder, elevator, and thrust reverser and fairings around antennas. A summary of operational limitation is given in Table A.3.

Power Plant

The engine is a two-shaft high-by-pass ratio Rolls-Royce BR710 C4–11 turbofan engine with a single-stage low-pressure compressor, a ten-stage high-pressure compressor, a two-stage high-pressure turbine and a two-stage low-pressure turbine. The engine is equipped with FADEC. Basic data are shown in Table A.4. The engines are mounted high in the aft fuselage through horizontal pylons.
