Hartzell Engine Technologies Announces DAHER-SOCATA Has Selected its New Lightweight ES-Series Standby Alternator as Standard for the New TBM-900

DAHER-SOCATA has selected the new lightweight, 100-amp ES-10024B-5 unit as the standby alternator aboard the new-generation TBM-900 – the latest addition to its family of very fast, single-engine turboprop aircraft.

Montgomery, AL, April 07, 2014 — Mike Disbrow, president of Hartzell Engine Technologies LLC, announced today that DAHER-SOCATA has selected the new lightweight, 100-amp ES-10024B-5 unit as the standby alternator aboard the new-generation TBM-900 – the latest addition to its family of very fast, single-engine turboprop aircraft.

“The TBM-900 is a truly advanced airplane and we are very proud to have our lightweight, 100-amp standby alternator selected as standard on this exciting new aircraft,” Disbrow stated. “While the new ES-10024B-5 shares technologies with other Hartzell alternator units, this model has been developed specifically to meet the unique power requirements of the TBM-900’s completely revamped electrical system.”

“We selected the new Hartzell alternator for a variety of reasons: the company’s reputation, the new technologies they offered, the unit’s light weight, and the most important reason – with 100 amps, it gives the pilot the options to select what needs to be loaded in the event of a main generator failure,” stated Nicolas Chabbert, President and CEO, SOCATA North America. “It also allows us to contemplate other applications for the TBM Multi-Mission, such as medevac with the adequate level of power especially on stand-by.”

“DAHER-SOCATA’s engineering group came to us early in the aircraft’s development program to create a new lightweight alternator that would not only meet their stringent requirements, but also conform to the revisions outlined in the latest FAR23 rules,” he said. “This new, ES-Series alternator meets, and exceeds, everyone’s performance goals.”

Disbrow said that in order to meet the current regulations, DAHER-SOCATA needed a “self-exciting” standby alternator that is able to come on line to power to the TBM-900’s electrical system and its Garmin G1000 avionics suite in the extremely unlikely event of a failure in the primary generator and battery.

“This design retains a small amount of residual magnetism, so when it is switched on by the crew, the new ES-10024B-5 has the ability to develop 100-amps of electrical power without the use of a separate power source,” he explained.

“DAHER-SOCATA’s selection helps us maintain our leadership position as a provider of alternators for today’s leading single-engine turbine aircraft supplying standby, secondary and even primary electrical power,” Disbrow said. “In addition to the new TBM-900, we provide alternators for the Cessna Caravan, Piper Meridian and the forthcoming Cirrus SF50 Vision personal jet.” 

About the new Hartzell ES-10024B-5 standby alternator

The new-generation ES-10024B-5 alternator has been developed specifically to meet the demanding requirements of the DAHER-SOCATA TBM-900’s completely revamped electrical system. The ES-10024B-5 provides a number of key features including:

• “Self exciting” capability enables alternator to power-up without the aid of external battery or generator power

• 36% greater power density than the 80-amp unit it replaces

• Integrated fan and flow-through cooling to ensure reliable performance in high-temperature environments

• Compact frame size – generates more power output without increasing the frame size to ease packaging in the limited space under the cowling.

About the TBM aircraft family

DAHER-SOCATA’s TBM family of fast single-engine turboprop aircraft combine cruising speed and trip times of a light jet with the economic direct operating costs, range and moderate environmental signature of a turboprop engine. The maximum range and useful load, as well as the ability to land at small airports, are some of its customers’ favorite features. More than 660 TBM aircraft have been produced and delivered to date. Operated in 35 countries, the TBM fleet has logged a combined 1.1 million flight hours. For more information, visit: www.tbm.aero.
