Weapons and Weapon Bay Analysis

Future manned and unmanned air combat platforms are likely to make use of internal carriages for ordinance. While providing advantages for stealth, there are a number of challenges to be overcome such as acoustic footprint, ordinance releasing and fatigue due to structural vibration.

Utilising the power of ARA’s computational fluid dynamics toolset has enabled ARA to provide inputs to weapon design cycles, analysis of isolated and carriage aerodynamics, prediction of release characteristics and examination  of non-conventional stores (free-to-rotate cruciform tail sections for example).

Why ARA?

ARA has a high level of experience in the accurate simualtion of aerodynamic performance and the deployment of weapons from a variety of operational platforms, both of which are vital in the military sector.

Our expertise in aerodynamics (from low to supersonic speeds) and aeroacoustics allows our experts to provide specialist  inputs to weapon bay analysis. ARA has been, and continues to be, involved in high-level cavity research.

ARA uses a wide range of aerodynamic simulation techniques to analyse the following:

  • Isolated weapon aerodynamics
  • Installed weapon aerodynamics
  • Weapon bay characteristics using Detached Eddy Simulations (also nose landing gear and cavity analysis)
  • Gliding weapon wing design
  • Inlet and duct analysis
