Hartzell Engine Technologies lightweight starters

Hartzell Engine Technologies (HET) has recently introduced a family of new-generation starters including the lightweight E-Drive, X-Drive and M-Drive units.

To meet the demand for lighter weight and improved performance, HET took a new approach to starter design. The E-Drive and X-Drive (for Lycoming engines) and the M-Drive (for Continental engines), were developed specifically for aircraft engine applications.

While all the units represent significant leaps in starter performance and reliability, HET’s E-Drive is truly the culmination of the best starter technologies available for Lycoming engines.

Highlighting the E-Drive’s many improvements is HET’s immunity to the kick-back problems that plague prior-generation starters. The E-Drive features a proprietary drive system that allows the starter’s pinion to rotate in the non-standard direction once the torque threshold is reached. Utilizing a tuned detent clutch mechanism, the unit automatically permits the mechanical release of the damaging energy from the kick-back without harming the starter. The system is automatically re-setting so the starter is ready to go after a kick-back event.

HET’s kick-back immunity technology not only makes the engagement system more durable, it makes the entire starter more robust and damage tolerant. Hartzell Engine Technologies was the first manufacturer to bring this technology into the aviation industry.

To further ensure that these new starters would provide years of service, the company did static and dynamic load testing on the unit’s housing and mounting pad. Tests show that the X-Drive is 30% stronger, from a structural standpoint, than the competitive unit.

All of Hartzell’s new design, E-, X- and M-Drive starters provide the best combination of balanced power, cranking speed and torque to start the engine. This optimized performance puts less power drain on the aircraft’s electrical system, making it a true improvement over old-generation starters, especially when the aircraft’s battery is below optimum charge.
