Development
In March 1983, Gulfstream, together with Grumman, began developing a new Gulfstream IV aircraft, which was supposed to replace the Gulfstream III model. Gulfstream IV received a new wing design: weight reduction and shape change allowed to improve aerodynamic performance, reduce airflow resistance and increase flight range. Various aerodynamic improvements have led to an increase in flight range of 300 nautical miles .
From the predecessor aircraft Gulfstream III, the new jet differs with a new wing, a long fuselage, which received a sixth porthole, an increased flight range, a new cockpit with EFIS devices (electron beam display) and aviation digital electronic equipment based on multi-function indicators, as well as new engines RollsRoyceTowMk611-8. [5]
September 19, 1985 the first plane made its first flight. The certificate of airworthiness was obtained in April 1987. [6] The first GIV aircraft was delivered to the customer in 1987 under serial number 1000. [7] Later, the GIV-SP modification (special mission, as well as the G300 and G400 modifications ) was presented.
In 2001, work began on creating a new aircraft based on the GIV-SP (the project was originally called the GIV-X , but was later renamed the G450). In 2004, the G350 was introduced, an aircraft similar to the G450, but with a shorter flight range. [8]
Operation
The National Oceanic and Atmospheric Administration uses GIV-SP (N49RF) to study tropical cyclones. The aircraft is equipped with special equipment for measuring humidity, pressure, temperature and is used in extreme conditions to study atmospheric phenomena and predict the movement of hurricanes and storms. [9]
In June 1987, Gulfstream IV set 22 world speed records in its class. [10]
Versions
The Gulfstream G450 received a certificate of airworthiness on August 12, 2004. Gulftstream G450 is one of the most reliable aircraft. Prices for it range from 15 to 32 million dollars, depending on the age and condition of the aircraft. The G450 is one of the few large jets for business jets with a capacity of up to eight people at a distance of 7960 km at a cruising speed of 0.8 M (with a reserve fuel reserve for flights up to 370 km). Compared to the first and second generation Gulftstream IV models, the G450 aircraft have a number of design improvements aimed at reducing aerodynamic drag, modernized Rolls-Royce Tay Mk 611-8C turbofan engines with a digital automated control system (FADEC), as well as a more powerful and less noisy APU. [eleven]
The G450 business jet retained the basic part of the Gulftstream IV fuselage with a bow section, borrowed from the Gulftstream V airframe, but is distinguished by the presence of an automatic electric system and pressure control system, higher pressure in the aileron booster system, an anti-icing system with automatic control and other changes. The length of the bow section increased by 30.5 cm provided additional legroom for pilots, as well as a more comfortable folding chair for the third crew member.
At the end of 2014, more than 330 aircraft were in operation. [12]
