How do I order an Isengard TJ-100 or TJ-40 turbine?

Add the engine and quantity to a request on the turbines page, or contact hello@isengardindustries.com. Order minimums are 4 units for the TJ-100 and 8 units for the TJ-40. Pricing and ship dates issue only after export-control review, and sales are limited to allied end users.

What is the lead time for Isengard turbines?

14 weeks for the TJ-100 turbojet and 10 weeks for the TJ-40 compact turbine at standard order quantities. Volume programs are scheduled separately and can lower both unit cost and per-unit lead time.

How much thrust does the TJ-100 produce?

The TJ-100 is a single-spool turbojet in the 1,000 N (approximately 225 lbf) thrust class, running on Jet A-1. It is TRL 9, combat-tested, and in production. Two TJ-100 engines power the XQ 770 Freedom Fighter.

What are the TJ-40 turbine specifications?

The TJ-40 produces 392 N (40 kgf) maximum thrust at 100% RPM with a 10.8:1 dry thrust-to-weight ratio. Maximum rotational speed is 98,000 rpm, compressor pressure ratio 3.8:1, dry weight 3.7 kg, outer diameter 148 mm, overall length 370 mm, fuel consumption 1.2 l/min on Jet A-1 or kerosene.

Can Isengard co-develop a turbine for my platform?

Yes. Isengard produces high-volume engines configured to a customer's mission profile - thrust class, envelope, mounting, and nozzle designed around the airframe rather than the reverse. Submit your program details through the co-development form on the turbines page.

Why in-house

Engineered for the airframe.

Propulsion is the bottleneck most strike systems never solve. Isengard designs and builds its own turbojets - combat-tested, rate-producible, and tuned for the platforms they fly.

Packaging

Compact & light

Tightly packaged envelopes for straightforward UAV integration across the strike line.

Response

Rapid throttle

Fast spool dynamics for responsive tactical control, with a fuel-efficient cycle that extends endurance.

Production

Rugged & rate-ready

Built for mass production and field reliability - customizable nozzle and mounting options per platform.
