TSLM - VR Avionics

TSLMs are automatic start controllers for gas-turbine engines that allow electric fuel augmentation to the combustion chamber. During a start cycle the TSLM regulates the turbine temperature to follow an optimum curve versus time and engine speed. It also automatically actuates the starter, igniters, as well as actuators that atomizes the fuel to obtain good light-off. Its automated process provides simplicity of operation, more consistant and successful starts, guarding and guiding against hot starts, and much more. The table below lists the functions and features of our two TSLM models, and links to their respective specification sheets.

Engine Monitoring

The TSLM senses most, if not all, engine operational parameters, some being required for control, while others are solely informational. A warning light will annunciate not only when the TSLM detects a problem during a start but afterward (during flight) when particular parameters exceed their limits. The TSLM further shares all operational information with other devices, including our DX1. The latter thus effortlessly realize in-cockpit engine instruments. All parameters get logged not only during every start but when one or more exceed a limit. These can be retrieved and analyzed later.
