Pratt & Whitney's
PW210S Engine Receives Transport Canada Certification
By Mike Mitchell
October 24, 2011 - Pratt & Whitney has received
Transport Canada type certification for its PW210S
engine, selected by Sikorsky for the S-76D medium-sized
helicopter targeting corporate, offshore oil, medical,
airline and government operators around the world.
"This is a terrific milestone for this exciting and
game-changing helicopter engine program," said John
Saabas, President of P&WC. "The PW210S has been designed
to offer the highest power-to-weight ratio and lowest
fuel burn in the market, which translates into payload
and range benefits for the helicopter. With this key
certification, we are now looking forward to moving into
the production phase of this program."
The PW210S incorporates the most recent advances in materials and compressor design, including dual-channel FADEC (full-authority digital engine controls) for ease of pilot operation and training, state-of-the-art diagnostics capability, including automatic fractional cycle counting, automated power assurance, unmatched operating economics and rugged design.
is the launch customer for the PW210S, a new-generation engine
for large single and intermediate-to-medium twin helicopters in
the 1,000 shp class. Sikorsky's S-76D helicopter achieved first
flight on February 7, 2009 and its test flight program is
continuing, with helicopter certification scheduled for 2012.
is a member of the PW210 engine family and designed to deliver a
wide-range of power while delivering P&WC's legendary
performance in reliability and durability. "The PW210
demonstrates our firm commitment to developing innovative
products designed and built to satisfy customers' ever growing
needs and expectations," said Saabas.
Sikorsky S-76 is an American medium-size commercial utility
helicopter. The S-76 is powered by two turboshaft engines, which
drive both the main and tail rotors, each with four blades. The
S-76 landing gear is retractable.
Development of the follow-on S-76D model has been subject to delays due to technical problems in expanding the flight envelope. It will be powered by 1,050 hp (783 kW) Pratt & Whitney Canada PW210S engines driving composite rotors and will incorporate active vibration control.
have been used in the certification program. One aircraft will be used
to obtain certification of an optional electric rotor ice-protection
system. Performance is anticipated to be substantially improved with the
added power, but initial certification will retain the same 11,700 lb
(5,307 kg) gross weight and maximum 155 kn (287 km/h) cruise speed.
?We have conducted
a robust test program to ensure that this engine is ready to enter
service, so this is a key milestone in the development of the S-76D
helicopter,? said Tim Fox, S-76? helicopter Senior Program Manager. ?It
demonstrates that the engine?s capabilities meet or exceed regulatory
requirements. It propels Sikorsky another step closer to certification
of this exciting new aircraft.?
Fox said the
Federal Aviation Administration (FAA) validation, followed by the
European Aviation Safety Agency (EASA) validation, of the Canadian Type
Certificate is expected in the coming months. Delivery of the first
aircraft to the launch customer is slated for 2012.
?With every milestone achieved by the S-76D helicopter program, the legacy of the Sikorsky S-76? series grows,? said Ed Beyer, Vice President of Sikorsky Global Helicopters. ?The medium-size helicopter market is ready for the enhanced functionality, improved quiet ride, and power that the S-76D helicopter offers. Our customers are embracing the advances in technology and new efficiencies, and we are focused on delivering on all counts.?
The new generation
S-76D helicopter will perform an array of civil missions including
executive transport, offshore oil, emergency medical services, and a
Among the S-76D helicopter?s features are all-composite, flaw-tolerant
main rotor blades; an advanced THALES integrated avionics system and
autopilot; quiet operation with active vibration control; powerful Pratt
& Whitney Canada PW210S engines; and an optional Rotor Ice Protection
System (RIPS) for all-weather capability.
