The Design Bureau’s team consists mainly of specialists from the aviation industry, thus determining the main focus and experience with aviation systems. Our work is based on aerospace industry standards, defining the strict requirements for product quality and reliability. We provide modeling and simulation services for systems and components debugging.

Modern products consist of a large number of mechanical, hydraulic and electronic subsystems.
For successful market introduction, it is necessary to test the systems as a whole: both mechanical and control systems. As the degree of automatic control increases, the range of design loads expands.
Proper computational load generation (test program) is a separate task for the designers. The system and unit design team needs to be able to simulate different operating scenarios.

Avia simulator is a complex solution from Urartu Systems for model-based system calculations of dynamic characteristics for aviation components and assemblies in real-time. To increase efficiency and reduce risk, engineers can test ECUs virtually, using software models to simulate various components. All aviation components present in the simulator can be tested both independently and in combination with each other.

The designers can load mathematical models of physical objects, parametrically adjust the model. Then the model is tested on the HIL simulator considering design loads and impacts that are close to operational ones.

System modelling

GTE Simulation Library

GTE Toolkit allows to create a GTE model for execution virtual tests when solving design problems and refinement of gas turbine engines, development of their systems management and diagnostics. GTE models are created on the basis of mathematical models, describing thermogasdynamic processes, occurring in the main components of the engine. Complied conditions for the joint operation of all components in the engine, including equations of continuity, balance power and pressure balance.

Fuel System Modelling

Fuel Systems Toolkit solution enables creating models of fuel systems of different aircrafts and conducting their virtual testing.
Tasks to be solved:

  • design calculation
  • performance calculation
  • сalculation of characteristics of individual assemblies and units
  • simulation under various operation modes and flight conditions.

Landing Gear Modelling

Shock absorber model of landing gear support for testing loads and test program.

The model allows to simulate dynamic processes of hydraulic shock absorber drive and select optimal coefficients of PID controller, with increasing and staggered setting of shock absorber rod speed. The model has a flexible parametric structure that allows to create models of the landing gear of various aircrafts.The model allows real-time calculations.

Hydraulic Systems Modelling

The hydraulic system model allows calculations in stable and transient modes.  As a result the main parameters and characteristics are determined:

  • hydraulic losses
  • working fluid flow rate
  • pressure
  • hydraulic shocks when the valves are activated
  • flow and differential characteristics of the valve
  • simulation of different valve models
  • simulation of multiple valves working together
  • study of high-frequency unit valve phase shifts.

HIL Simulator

The HIL simulator provides real-time testing and takes into account the control systems, sensors and actuators of the system.

The data obtained from the test site can be used to:

  • defining the boundary conditions.
  • adjustment of the control system algorithms;
  • formation of the test program and tasks for the test benches.
