TJDU Panel Display - The TJDU provides a display of all important engine functions. They are reliable and fit in a standard 2.25" instrument hole. Information is color-coded with bar graphs, indicators and digital display of EGT and RPM. Bus voltage is also displayed. Panel has dimmer. Easily accessible SD card logs engine data in CSV (Excel) format. Additional screens show total times and last flight times. The TJDU firmware may be configured for single or dual engine operation.

 

The TJDU display has been in operation for many years. The TJDU is currently manufactured in Europe, but units are usually in stock in the USA.

EGT probe - New EGT probe replaces at a fraction of the cost of a new PBS unit. Connectorized EGT probe allows easy replacement. EGT probe comes with connector pins installed. Modification of the EGT wires is required. Kit comes with connector pins & and loaner pin crimp tool. Once pins are installed, original EGT probe may still be used.

 

The first prototype has been installed and tested. We made some minor changes to make wire routing easier. Second prototype due early April. We expect to accept orders mid-April. The EGT probe is manufactured in the USA.

​

Engine Control unit (ECU) - The heart and brain of the engine, the ECU controls the function of all active engine components to ensure smooth, safe engine operation. The Liberty Turbines ECU will feature upgraded safety and reliability features, including dual EGT monitoring, customer-adjustable settings, and on-screen error, caution and warning notices, which allow the pilot to make important operation choices in the even of off-nominal conditions. It will also feature easily accessible on-board data logging.

 

We are discussing the design with several companies capable of producing new ECUs. We are in the process of writing the design and control documents for their production. We expect the first new ECUs by late summer.

​

​

Compressor wheels - We are designing a new compressor wheel to replace the original wheel.The design is nearing completion. 

 

We expect new wheels for testing soon.

​

​

Turbine blisk - We have designed a new turbine blisk to replace the one affected by the 2024 Service Bulletin. We believe we have solved the turbine blade resonance issue of the PBS unit.We expect to be testing the first batch of these components soon. We expect to be accepting orders by late summer.

​

​

Overhauls and inspections - Our certified engine specialists will overhaul your TJ-100 engine. The turbine blisk will be inspected and/or replaced and rotating components balanced. All internal components will be inspected and repaired or replaced. All seals will be replaced with upgraded materials. Once overhauled by Liberty Turbines, the engine will be placed on a new, reasonable  inspection/maintenance/overhaul schedule with age-related maintenance removed. Our first complete overhaul will be in mid-April.
