LinerTherm™- Computer Program for Thermal Analysis of Aircraft Cooling Liners

A user-friendly heat transfer/thermal modeling code, LinerThermTM, has been developed
for rapid analysis of aircraft exhaust liner cooling systems. Most of the thermal modeling
codes on the market today fall into one of two categories either they are complex 3-D codes
requiring significant engineering resources or they are simple conduction models that lack
advanced convection capabilities required for high performance aerospace and propulsion
cooling applications. In the high-tech field of aerospace propulsion, it is necessary that rapid
modeling of complex thermal systems be accomplished to enable the trade studies required
to optimize aircraft cooling liner designs for weight, cost, and performance. This code
performs detailed thermal analysis of gas turbine exhaust liners used in the augmentor and
nozzle and includes cooling capabilities for impingement, multi-hole film-cooled, slot filmcooled,
and convectively cooled liners. Its simple user interface provides the capability of
performing quick trade studies for a vast array of cooling liner designs, including a wide
selection of included materials.
