The Bombardier Challenger 600 series is a family of business jets.
Original production version, powered by Lycoming ALF 502 turbofans of 33.6 kN thrust each. Built from 1978 to 1982 (81 built).
While the Challenger is generally similar in configuration to previous aircraft of its type, some of its features stand out; for example, the use of a widened fuselage that allows a “walk-about cabin”. The Challenger was also one of the first business jets to be designed with a super-critical wing.
Akin to other supercritical wings, it features a rounded leading edge, an inverted camber, a blunt trailing edge and scalloping of the underside. The twin-spar wing box structure spans the entire length of the wing and is compartmentalised to form internal five fuel tanks; these tanks can accommodate up to 14,661lb of fuel, nearly half the aircraft’s empty weight.
