BMW is associated with Rolls-Royce. The company is called BMW
Rolls-Royce Aero Engines. This joint company makes airplane engines for
regional jets, large corporate jets and transport aircrafts. BMW AG,
München owns 50.5% and Rolls-Royce plc London owns 49.5% or the company.
Seven and a half years since it was formed on
July 1st, 1990, BMW Rolls-Royce GmbH has become a leading European
manufacturer of civil aero engines.
BMW Rolls-Royce GmbH was established as an
independent company by BMW AG and Rolls-Royce plc. Rolls-Royce, one of the
world´s leading aeroengine manufacturers, contributes decades of
experience in engine design and construction, together with its worldwide
service network. BMW provides system-related technical know-how. Direct
access to current aviation programmes was assured by acquiring
Motorenfabrik Oberursel, itself established as long ago as 1892 and today
the headquarters of BMW Rolls-Royce
The rotating propeller, BMW's company logo,
symbolizes the fact that BMW started its life as an aero engine
manufacturer in 1917. Prior to that, German aero engines were being
developed and supplied by Motorenfabrik Oberursel, the site now owned and
operated by BMW Rolls-Royce GmbH. BMW later moved to the automobile
industry via the development and production of motorcycles. The opposite
was the case at Rolls-Royce. The company was established in 1906 as an
automobile manufacturer with aircraft engines a later addition. BMW and
Rolls-Royce simultaneously but completely independently developed the
world's first production jet engines. They were used in 1944 in the German
He 162 and in the RAF's Gloster Meteor respectively. Whereas BMW left the
aerospace industry in 1965, Rolls-Royce became Europe's major aircraft
engine manufacturer - its automobile manufacturing operations were at that
time already completely separate.
When the Oberursel Motorenfabrik was
purchased, its current contracts and business undertakings were honoured.
At the centre for small gas turbines at Oberursel, maintenance, repair and
overhaul services continue to be performed on engines for civil and
military aircraft. In addition, BMW Rolls-Royce produces specific
components for Rolls-Royce engines and other civil aero engines. Business
in small gas turbines has also been expanded to the civil sector.
The aim of establishing BMW Rolls-Royce was to
design, build and certify a new aero engine family, the BR700 series,
based on a common core. The concept of a whole family of engines greatly
increases the versatility of the project and the likelihood of commercial
success. The low-pressure system integrated into the core engine can be
adapted to provide the thrust values called for by individual aircraft
The core engine, which is identical for all
versions of the BR700, has a ten-stage high-pressure compressor, an
advanced combustion chamber and a two-stage high-pressure turbine. The
BR710 has a 48 inch fan and a 2 stage low-pressure turbine. It has a
thrust of between 14,000 and 17,000 pounds (62-75.6 kN). The low-pressure
system of the BR715 engine consists of a 58 inch wide-chord fan with a
two-stage booster, plus a three-stage low-pressure turbine. The BR715 has
a thrust range of bewteen 17,000 and 23,000 pounds (75.6-102.3 kN),
depending on the aircraft's specification. The BR710 engine is the first
engine ever to be developed and produced in Germany by a German company
and receive international certification.
The BR710 engine is designed to power the new
generation of large, ultra long-range corporate jets. It is also ideally
suited for 80 - 100 seater regional aircraft. The more powerful BR715 is
optimised for 90 - 140 seater regional jets and large transport aircraft.
In 1992 the BMW Rolls-Royce BR710 was selected
by Gulfstream Aerospace of Savannah/Georgia, U.S.A., as the sole engine
for the Gulfstream V large, ultra long-range business jet with an initial
order of 200 BR710 engines at 14.750 lb thrust. Only six months later, the
Canadian manufacturer Bombardier of Montréal/Québec, Canada, chose the
BR710 exclusively to power the Bombardier Global Express large, ultra
long-range corporate jet. Today BMW Rolls-Royce is the sole supplier of
engines in this market segment.
In 1994 the BR715 engine was selected as the
sole powerplant for the McDonnell Douglas MD-95 aircraft programme and in
October 1995 the U.S. carrier AirTran Airlines (formerly ValuJet Airlines
became the launch customer for both the engine and the aircraft when it
placed a firm order for 50 MD-95 aircraft and 110 BR715 engines with
options for a further 50 aircraft.
On the 8. January 1998, the Boeing Company
renamed the aircraft 717-200 and introduced it as the newest member of its
commercial aeroplane family.
In July, 1996, the BR710 engine was chosen to
power the Nimrod 2000, the British Royal Air Force´s maritime patrol
aircraft, as part of a comprehensive modernisation programme involving the
replacement of the propulsion systems. The order is for 87 marinised
engines and it brought the company's total order volume to over 2.5
Throughout seven and a half year history BMW
Rolls-Royce has met its deadlines in its very demanding time schedule. The
core engine ran for the first time on August 14, 1993. This was followed,
on September 1 1994 by the first run of the first full engine version, the
BR710, right on schedule, at the company's high-tech development, test and
assembly centre for the BR700 family in Dahlewitz. On August 14th 1996, on
schedule, BMW Rolls-Royce reached its most important milestone to date
when the BR710 engine received approval from the European Joint Aviation
Authorities. This was followed a month later by Certification from the
U.S. Federal Aviation Authorities in September. The engine is now in
service powering the Gulfstream V corporate jet. On October 13th, 1996,
the Bombardier Global Express corporate jet powered by BR710 engines had
its maiden flight. It is now undergoing an eighteen month flight test
programme before entering into service in spring 1998.
Rated at 18,500 pounds thrust with an optional
increase of up to 21,000 pounds thrust, the BR715 engine for the Boeing
717-200 ran for the first time on 28. April 1997 and the first engine was
shipped for delivery to the Douglas Products Division of Boeing Commercial
Airplane Group in Long Beach, California. Certification of the engine is
scheduled for autumn 1998 followed by Entry into Service powering the
717-200 in mid 1999.
In June 1997, during the Paris Airshow, BMW
Rolls-Royce signed an agreement with the Russian aircraft manufacturer
Tupolev to power its Tu-334 100-seater regional jet with BR710 engines.
The BR715 engine is also being offered for the Chinese AE31X and the
Indonesian IPTN 2130 100-seater aircraft.
A BR700 turboprop engine with 9,000 - 12,000
shaft horsepower is being proposed for the new European Future Large
Aircraft military transporter.
