Gulfstream Aerospace, founded in 1958, is renowned for its cutting-edge business jets. Originally part of Grumman Aircraft Engineering, it separated to form Gulfstream Aerospace, developing notable aircraft like the Gulfstream G700. Now, Gulfstream is on the brink of certifying the G400, featuring new Pratt & Whitney engines, a shortened cabin length, and a high maximum operating speed of Mach 0.90.
Gulfstream Aerospace is well-known globally for its approach to developing and manufacturing state-of-the-art business jets. Originally, the company was founded in 1958 and is currently based in Savannah, Georgia. The company was founded as a part of Grumman Aircraft Engineering, which typically developed military aircraft. However, in the early 1950s, Grumman Aircraft Engineering designed a business aircraft. This turboprop aircraft was called the Grumman Gulfstream and was designated as the G-1. As the program commenced, to improve engineering efficiency, Grumman officially separated the program into its own company, which was later called Gulfstream Aerospace.
Since then, Gulfstream has gone on to develop some of the world’s most notable business jets. This includes the recently certified Gulfstream G700, which has the longest range of any business jet worldwide, narrowly beating out the Bombardier Global 7500. Gulfstream is also working to certify another ultra-long-range business jet called the G800, which will surpass the G700’s already long range.
Another one of the company’s soon-to-be-certified aircraft is the Gulfstream G400. This smaller variant of the successful G500 and G600 is currently under development by the Georgia-based manufacturer. Let’s take a closer look at some of the features the Gulfstream G400 is expected to have.
1. New Pratt & Whitney engines
The Gulfstream G400 will utilize two Pratt & Whitney Canada PW812GA turbofan engines.
Gulfstream has stated that the G400 will utilize a set of new Pratt & Whitney Canada PW812GA turbofan engines. Transport Canada officially certified this engine in September 2022, allowing it to be installed on the aircraft. The addition of brand-new engines has complicated the certification process for the G400, however. After the Federal Aviation Administration (FAA) strengthened certification requirements after the Boeing 737 MAX groundings, Gulfstream began anticipating a more extensive certification campaign for the G400 aircraft. This also represents a lengthier flight-test process for the five prototype G400 aircraft that are in development.
These engines will provide nearly 14,000 pounds of force in maximum thrust. After the engine was certified in 2022, Maria Della Posta, President of Pratt & Whitney Canada, spoke about the success, stating,
2. Shortened cabin length
The G400’s cabin is expected to stretch 86.3 feet.
The Gulfstream G400 will have the second-shortest cabin length in the currently produced Gulfstream fleet, behind only the Gulfstream G280, which has a cabin length of 66.9 feet. The G400 will share the same fuselage cross-section as the previously certified G500 and G600.
The G400 will have the following interior cabin dimensions:
Cabin length: 36 feet four inches
Cabin width: seven feet seven inches
Cabin height: six feet two inches
The G400 will be built to fit two and a half interior zones. This means the aircraft can fit up to 12 passengers and can sleep up to five passengers, depending on the configuration.
3. High maximum operating speed
The aircraft can reach a maximum operating speed of Mach 0.90 (594 miles per hour).
As previously mentioned, the G400 will be powered by two brand-new Pratt & Whitney Canada engines. Combined with the shorter fuselage length, meaning it has a lighter overall weight, the G400 is projected to reach high cruise speeds and maximum operating speeds but still requires a relatively short takeoff distance.
