An interesting feature of all three German jet engine designs that saw production of any kind before May 1945: the German BMW 003, Junkers Jumo 004 and Heinkel HeS 011 axial-flow turbojet engine designs was the starter system, which consisted of a Riedel 10 hp (7.5 kW) flat twin two-stroke air-cooled engine hidden in the intake, and essentially ...
The 131-9D initially was designed for the McDonnell Douglas MD-90 series; the 131-9B became standard equipment on Boeing 737NG; the 131-9A on the Airbus A320 family. [4] The 131-9C has entered service aboard the Airbus A220 (formerly Bombardier C-Series). The 131 Series uses a two-stage axial turbine and a single generator which starts the APU. [5]
The 22-blade fan of an A320's V2500-A1 Rolls-Royce based the ten-stage high-pressure compressor on an eight-stage run in the RB401 in the mid 1970's followed by a nine-stage run in the RJ.500 . The V.2500 would use ten stages, with the first four with variable stators, giving a pressure ratio of 20:1. [ 4 ]
The Airbus A320neo family is an incremental development of the A320 family of narrow-body airliners produced by Airbus.The A320neo family (neo being Greek for "new", as well as an acronym for "new engine option") is based on the enhanced variant of the previous generation A319, A320, and A321, which was then retrospectively renamed the A320ceo family (ceo being an acronym for "current engine ...
The Airbus A320 family was the first airliner to feature a full glass cockpit and digital fly-by-wire flight control system. The only analogue instruments were the radio magnetic indicator, brake pressure indicator, standby altimeter and artificial horizon, the latter two being replaced by a digital integrated standby instrument system in later production models.
The first derivative of the A320 was the Airbus A321, also known as the Stretched A320, A320-500 and A325. [9] [25] Its launch came on 24 November 1988 after commitments for 183 aircraft from 10 customers were secured. [9] [26] The aircraft was to be a minimally changed derivative, apart from minor wing modifications and the fuselage stretch ...

A blended winglet is attached to the wing with a smooth curve instead of a sharp angle and is intended to reduce interference drag at the wing/winglet junction. A sharp interior angle in this region can interact with the boundary layer flow causing a drag inducing vortex, negating some of the benefit of the winglet.
