Aero Engines (IAE)
V2500 series engine
represents one of
the most successful
programs developed
for the single-aisle
market. IAE was established as a
partnership in 1983 between Pratt &
Whitney, Rolls-Royce, Japanese Aero
Engine Corp., MTU and Fiat Avio to
develop a powerplant for the Airbus
A320 family. Fiat departed the group in
1996, followed by Rolls-Royce in 2011,
but both remain suppliers.
With final assembly centers in
Middletown, Connecticut, USA, and
Dahlewitz, Germany, IAE manufactured
a number of different variants for
the single-aisle market consisting of
the V2500-A1 and A5 (A320 family)
and the -D5 (Boeing MD-90). Thrust
levels varied from 23,000 to 32,000
lbs. The problematic debutant, the
V2500-A1, was introduced in 1998
and lasted six years before being
superseded by the superior -A5 model,
which became IAE's most successful
variant with deliveries exceeding
7,600 units.
CFM International provided robust
competition through the CFM 565A/B,
which offered lower specific
fuel consumption (SFC) at lower thrust
levels, and consequently became the
dominant supplier on both the A319
and A320 series. Conversely, IAE

became the preferred supplier for the
A321 due to the V2533-A5's relatively
lower SFC and ability to meet Chapter
4 noise levels without modifications
to the nacelle (a distinct advantage
for IAE-powered A321 freighters). IAE
continues to manufacture V2500-A5
engines for the spares pool, with almost
70 units produced since the last IAE
equipped A320 was delivered in 2019.
