Modelling and simulation
We complete trade studies of concepts tested in operational scenarios by obtaining well-justified starting points for a solution architecture, configuration and layout. We have developed mission simulation codes for acquisition support, tactics development and training. This includes mission-level simulations for combat scenarios to model aircraft capabilities in operational and threat environments. We have also developed unmanned aerial vehicle and aircraft flight dynamics modelling, system identification, guidance and control and automation simulation tools.

Highlights
A safe, cost-effective way to understand aircraft behaviour
When South Africa acquired sophisticated fourth-generation Gripen fighter planes, pilots needed a full understanding of their advanced capabilities to develop new tactics and operational procedures. CSIR modelling and simulation specialists created a simulated, synthetic environment to enable this safely and cost-effectively.
Focus on computational fluid interactions
We use specialist computational codes to solve complex aerodynamic and fluid-dynamic problems for industries from defence to automotive design. Supported by significant computational capability, our work covers aeroelastic models, booster separation, molten metals, and moving bodies used for coastal defences.
Numerical modelling used to understand violent fluid sloshing in aerospace vehicles
Using expertise in computational fluid dynamics, we developed methods to model violent sloshing of fluids in large tanks. This helps predict structural impacts and improve the design of aircraft and space launch rockets.
Our research
The CSIR develops robust mission-level simulations for combat scenarios, modelling aircraft capabilities in the relevant operational and threat environment. These include air-to-air and air-to-ground mission simulations, multiple air and ground threat scenario simulations, parametric modelling of fixed- and rotary-wing flight models, as well as the modelling of various aircraft stores.
The SAAF utilises this capability to achieve an improved understanding of the mission environment necessary to develop and evaluate tactics against new threat scenarios. The SAAF used the CSIR-developed mission planning tool, based on the mission simulation system, to develop its doctrine and tactics, as well as to perform mission planning for the Gripen in preparation for the Soccer World Cup in South Africa in 2010.
