Unison Industries (Hall 4 Stand C14) has launched a new high-energy, high-temperature turbine engine ignition system designed to meet the “growing trend of climbing engine temperatures and combustion pressures.”

The Acclimate ignition system features solid-state electronics, with exciter performance that can vary depending on specific combustion and environmental requirements, according to Unison. This helps optimize ignition performance and overall system life, the company added.

When Gulfstream Aerospace of Savannah, Ga., unveiled the G650ER at EBACE, the company focused on the aircraft’s extended range of 7,500 nm, which makes it the world’s longest-range business jet (not including private airliners).

Snecma recently started flight-testing its Silvercrest turbofan on a modified Gulfstream II, a Snecma senior executive confirmed last week. AIN understands that the trials are taking place from Sierra Industries’ base in San Antonio, Texas. The maiden flight had been postponed several times but the delay is not expected to have any effect on the engine’s certification, planned for next year. The Silvercrest will power the Dassault Falcon 5X and Cessna Citation Longitude.

Turbomeca’s Ardiden 3G turboshaft engine has been chosen to power the Kamov Ka-62 helicopter; it is due to complete European certification in mid-2015.

Driven by the ambition to become world’s third largest turboshaft engine manufacturer after General Electric and Pratt & Whitney, France’s Turbomeca is pressing to establish a Russian partnership to develop and coproduce a new 3,000-shp engine based on the existing RTM322 powerplant and using the new Tech3000 core.

Microturbo’s e-APU has now been approved by the U.S. FAA.

Safran subsidiary Microturbo’s new e-APU60 auxiliary power unit received certification from the U.S. Federal Aviation Administration last month. It achieved European approval in May last year.

Titanium-aluminide low-pressure turbine blades and proposed cooling arrangements on Rolls-Royce’s proposed future UltraFan engine may owe much to the RB3025 powerplant unsuccessfully offered to power the Boeing 777X. For example, the RB3025 featured a “vortex amplifier” to simplify turbine-blade cooling with HPC air.

New engines planned by Rolls-Royce (R-R) reflect recent powerplant trends, including steadily increasing propulsive efficiency obtained with larger-diameter fans, higher bypass ratios and smaller engine cores. The engines could power updated contemporary widebody platforms, with R-R civil large engines president Eric Schulz confirming “very live” discussions with Airbus. “If it decides to re-engine the A330 or A380, we will be here to provide support,” he said during a pre-show briefing.

Pratt’s envisioned NGRT engine would feature an all-new compressor, a miniaturized version of P&W’s Talon combustor and possibly an eight-blade propeller.

While ATR and Bombardier continue to vacillate over plans to introduce a new 90-seat turboprop, Pratt & Whitney Canada keeps moving forward with a powerplant it believes will deliver a 20-percent fuel burn improvement over existing engines in the 5,000- to 7,000-shp range by the turn of the decade. Dubbed the Next Generation Regional Turboprop (NGRT), the engine would feature an all-new compressor, a miniaturized version of Pratt & Whitney’s patented Talon combustor and (probably) an eight-blade propeller.

Legacy product support specialist Ontic (Hall 1 stand B13) is here at Farnborough 2014 announcing new “extended life solution” contracts, a local stamp of approval for its Singapore maintenance facility and “incredible growth” over the past 12 months, when total annual sales exceeded $30 million.

The technology stakes are high for the GE9X engine that will power Boeing’s new 777X twinjet, but GE Aviation believes its big bet on the weight savings to be delivered by unprecedented use of composites is about to pay off. The U.S. engine maker, which currently holds orders for some 600 of the engines, is leaving nothing to chance and, with more than two years of technology maturation behind it, the company is now stepping up its test program en route to certification in 2018.

Artist’s impression of Bloodhound SSC during a record run. The actual record attempts are planned to take place in South Africa in 2016.  The car is appearing at Farnborough before heading for South Africa.

It is ironic that a Scottish entrepreneur who failed to make a success of two innovative aviation projects has had more success in what many would consider the much riskier world of land-speed record breaking.

A qualified pilot, Richard Noble created ARV Aviation in 1983 to design and build an all-British light aircraft: the Super2, which was powered by a Hewland AE75 three-cylinder two-stroke engine, but only 35 were made before production ceased.
