The Lockheed JetStar is a business jet produced from the early 1960s to the 1970s. The JetStar was the first dedicated business jet to enter service, as well as the only such airplane built by Lockheed. It was also one of the largest aircraft in the class for many years, seating ten plus two crew.
It is distinguishable from other small jets by its four engines, mounted on the rear of the fuselage, and the “slipper”-style fuel tanks fixed to the wings.The JetStar has a fairly typical business jet design layout, with a swept wing and a cruciform tail. The wing has a 30° sweepback and features large fuel tanks at about half-span, extending some distance in front and behind the wing.
The wings hold 10,000 pounds of fuel, and each slipper tank holds 4,000 pounds of fuel for a total fuel load of 18,000 pounds. The JetStar is a relatively heavy aircraft for its class, at 19,278 kg. Maximum cruising speed is Mach 0.8, or 912 km/h at 6,401 m.
Range is typically quoted as 4,023 km with a 1,588 kg payload. Typically, interiors feature seating for eight with a full-sized lavatory, or a slightly denser arrangement for ten. The JetStar is one of the few aircraft of its class which allow a person to walk upright in the cabin, although to do this the aisle is sunk slightly so that the seats are raised on either side.
