1 Title of the Invention
Airborne system for accurate engine exhaust temperature measurement
with audio-visual alerts
2 Field of the Invention
5 The present invention relates to airborne electronics that. is associated
with 'the critical parameter measurements which are recorded for analysis
and diagnostic purpose as well as in warning generation to the flight crew.
3 . Background of the Invention
Engine exhaust temperature. is critical parameter in airborne application. It
10. refers the gases temperature during the internal combustion process in the
engine. Monitoring of this temperature is crucial for the perform_ance and
durability" of the engine. High exhaust temperature is indicative of the
efficient combustion but excessive temperature may lead to the issues
such as overheating and potential component damage ..
15 Controlling exhaust temperature is vital for optimizing engine efficiency. It
allows adjustment to the air fuel mixture and other p·arameters to ensure
proper" combustion, maximizing the engines performance while minimizing
fuel consumption. Aircraft engine operates under extreme conditions and .
~igh exhaust temperatures· help prevent overheating, which could lead to
. 20 damage and reduce the lifespan of the critical parts.
Exhaust temperature is a factor in emissions regulation. It affects the
combustion efficiency and composition of exhaust gases. Monitoring and
controlling these temperatures contribute to meeting environmental
standards and reducing the environmental impact of air travel. Excessive
25 exhaust temperatures can pose safety risks, potentially leading engine
failure or other critical issues.
Engine exhaust· temperature can reach extremely high temperatures . .
during combustion. Thermocouples are well suited for such applications as
they can withstand elevated temperatures making them reliable for.
