Gulfstream Aerospace (Booth S117, Static AD7) is highlighting its upcoming G400 this week atEBACE 2022, showing interior renderings and other details of the new model. Introduced in October, the plane is “the first new entrant to the large cabin class in more than a decade”, according to the American aircraft manufacturer. Unveiled at an event broadcast live from the company’s US headquarters Along with the G800, the G400 is the smallest member of the previously introduced G500/G600 family.
“It’s an all-new, completely new design,” said Vicki Britt, senior vice president of innovation, engineering and flight for Gulfstream. AIN. She noted several features the G400 shares with its larger siblings, including the high-speed wing and fin; Pratt & Whitney Canada PW800GA series motors; Gulfstream Symmetry flight deck with fly-by-wire controls; fuselage cross-section (6 feet 2 inches (1.88 m) high and 7 feet 7 inches (2.31 m) wide); and “Gulfstream Cabin Experience” interior amenities and features.
While the G500 and G600 succeed the G450 and G550, respectively, the G400 occupies a place in the Gulfstream lineup as a slightly larger aircraft than the company’s G280 super-midsize. “Designed and engineered with direct customer input,” the jet delivers what Gulfstream calls “long-range, high-speed performance; cabin comfort; and class-leading environmental efficiency.
Performance comes primarily from pairing the new wing and fin design with the PW812GA engines. Together they will give the G400 a predicted range of 4200nm at Mach 0.85 or 3950nm at high speed cruise of Mach 0.88.
It will be able to climb directly to 41,000ft and share the 51,000ft service ceiling with the larger Gulfstreams, and will additionally have steep approach capability to operate at airports requiring such performance. The G400 also promises a 30% gain in fuel efficiency over the G450, giving it a lighter environmental footprint, while offering what Gulfstream claims to be the largest cabin in its class.
Three cabin configurations will provide seating options for up to 12 passengers in up to 2.5 living spaces. Many elements of the cabin, from tables and sofa to switches and cup holders, are common to the G400/500/600 family. Ample storage space will also be provided throughout, the company said.
Complete with a convection oven and cool storage space, the G400’s kitchen will be similar to its larger siblings, as will the toilet. The cabin atmosphere is 100% fresh, which means there is no recirculated or refiltered air. Cabin air will be fully replenished every two minutes and passed through a plasma ionizing clean air system neutralizing 99.9% of airborne bacteria, spores and odors. Additionally, the G400 features the lowest cabin altitude in its class at 3,255 feet at FL400, like the G500 and G600.
The Symmetry avionics suite, which is common to the G500/600 and G700/800, contains 10 touchscreens, incorporating intuitive ‘phase of flight’ menus that place information where and when it is needed. The fly-by-wire flight control system is manipulated by electronically linked active side controls.
A Head-Up Display Combined Vision System, i.e. enhanced, synthetic vision systems incorporating terrain and 3D graphics, on the rider side is standard. The standard is also 3D weather radar and Gulfstream’s new Predictive Landing Performance System (PLPS), which continuously displays the aircraft’s projected landing point in its current configuration on the PFD during the final approach, giving pilots advance warning of potential runway excursions. The PLPS also includes a go-around advisory.
Behind the panel, a Data Concentrator Network (DCN) serves as the nerve center of the G400, routing data between aircraft systems that need to be kept current and providing a future-proof path to system upgrades based on the firmware. The DCN can also host programmable functions, so applications and other capabilities can be added to the system.
According to Gulfstream, production of G400 parts for the plane has begun and engine certification – the next stage of the project – is expected in the second half of this year, well ahead of the plane’s planned entry into service in 2025. The rapid development schedule is made possible by Gulfstream’s test labs and iron bird mockup, which Britt says enables software validation, evaluation of fly-by-wire controls and simulation of flight maneuvers. risky before building an actual aircraft.
“By the time these planes get to flight testing, we’ve spent thousands of hours with them in our lab test facilities,” she said.
At the October launch event, Gulfstream also unveiled a new showroom at its Savannah, Georgia headquarters where customers can select materials, designs and other choices for their custom interiors. . One of the focal points of the new facility is a full-scale mock-up of a G400, an aircraft that a company representative described as attracting “very strong interest”.
