We were recently approached by Burnley based Hurel Hispano to provide
additional resources for urgent work they were performing on the thrust
reverser assembly for a jet engine design for Honeywell.
Hurel Hispano are already users of MSC.visualNastran for Windows,
(supplied by ourselves), ensuring seamless interchange of models and
output files between our two companies.
We took their existing finite element models and results and extracted
load data for a wide variety of components within the thrust reverser
assembly to perform hand calculations. We then supplied the calculations
back to Hurel Hispano for incorporation into their overall report.
In addition to this work we performed a number of calculations on
a weight-reduced version of the assembly to ensure the revised design
still met the stress criteria dictated by the stringent Aerospace
standards.
The figure top right is of the thrust reverser assembly in the deployed
configuration with Von-Mises stress contours.
The figure below shows one of the two main beams of the thrust reverser
assembly.
As the main structural members, these take the highest loads and,
as expected, need to be analysed with great care and accuracy.
