Passive Throttle Quadrant Assembly

For a Future Fighter Aircraft


Passive Throttles for future aircraft.

Problem Statement
In cooperation with a customer, Ingenium Aerospace is developing a rear seat, passive, two engine throttle system for a future fly by wire (FBW) fighter aircraft. The Aft TQA contains a mechanical linkage to the forward auto throttle and three throttle position sensors per engine. The position sensors are used by the flight control computer to adjust engine throttle and features adjustable feel for the pilot and a detented gating system for the handle position to augment safe operation.

Passive throttles allow the pilot or the co-pilot to control the power setting of an aircraft’s engines by manually inputting a throttle level position, ultimately controlling the fuel flow. With extensive experience in cockpit controls, safety and redundancy management, and signal conditioning and control electronics, the Ingenium team has utilized basic customer provided requirements to provide extensive technical support for the future aircraft. Working cooperatively with the customer’s experts, the engineering team matured the requirements and finalized the passive Aft TQA performance details. The Ingenium product design team addressed all requirements including wire-routing, lock-outs, feel and gating systems, and break-away devices.

Results & Outcome
The TQA is currently under development at Ingenium Aerospace and on track to finish on time and within budget.
