LTS101 Turboshaft Engine

Brand：Honeywell Aerospace Model：LTS101

Challenging terrain and inclement weather won’t stop your fleet operations. That’s why operators count on Honeywell’s LTS101 turboshaft engine. The LTS101 offers the “hot and high” performance that helicopters need to lift heavier loads and to get the job done in fewer trips — helping you drive down operating costs.

LTS101 benefits include:
Potential 18% increase in helicopter value
22% increase in OEI power meeting EASA standards
Increased shaft horsepower
Honeywell’s LTS101 turboshaft engine is one of the most successful helicopter engines ever built. Since being certified in 1975, over 2,100 engines have been delivered to customers worldwide, logging over 11 million flight hours and powering airframes that include the Bell 222, Airbus/Kawasaki BK117, Airbus AS350 and the Avicopter AC311.

Today, Honeywell works closely with our trusted partners Airwork on the BK117-850D2; and Soloy and Heli-Lynx to offer retrofit programs for the LTS101 600A and 700D2 conversions. Our MRO partners – including Intermountain Turbine Service and Motorflug – provide global maintenance and repair capabilities, offer an affordable engine exchange program and provide a source for customers to obtain refurbished engines.

Connect with Honeywell or our trusted partners to find out why the LTS101 is the perfect choice to help you increase your fleet’s performance, reliability and operating efficiency.

FAQs

Frequently Asked Questions

What is the typical lead time for gas turbine overhaul services?

The lead time for gas turbine overhaul services ranges from 6 to 14 weeks, depending on the damage assessment, parts availability, and whether hot-section repairs are required. Expedited options may reduce this by 30%.
Do you provide customizations for legacy turbine control systems?

Yes, we retrofit legacy systems (e.g., GE Frame 5, Siemens V94.2) with modern digital controllers, typically completing hardware integration within 4-8 weeks. Software migration requires additional validation time.
How often should industrial gas turbines undergo performance testing?

We recommend annual performance testing under ISO 3977-2 standards. Critical applications (e.g., offshore platforms) may require semi-annual tests with emissions compliance checks.
Are your radiation-hardened (rad-hard) semiconductors compliant with MIL-PRF-38535?

All rad-hard devices (e.g., FPGA, ADC) are QML Class V certified under MIL-PRF-38535 and tested to MIL-STD-883 Method 1019 for SEU tolerance. Full qualification reports are available upon request.
What temperature ranges do your military-grade ICs support?

Our ASICs and power management ICs operate across -55°C to +175°C ambient temperatures, with derating curves provided in military temperature range (MTR) datasheets.
Are PMA parts interchangeable with OEM components?

Our PMA parts (e.g., actuators, sensors) hold FAA/EASA Form 1 certification and match OEM form/fit/function. Installation requires SB/MB documentation per FAA AC 23.1529.
What traceability standards do you follow for aircraft fasteners?

All NAS/MS fasteners include full DNA traceability: melt source (AMS 2301), heat/lot numbers, and AS9100-compliant MTRs with ultrasonic test reports.
How do you handle urgent AOG (Aircraft on Ground) requests?

AOG orders ship within 4 hours for stocked items (FAA-PMA, EASA Part 21G). Non-stock critical parts trigger priority manufacturing with 72-hour max turnaround.
