pSeven, with its Airbus roots, brings deep experience in Aerospace disciplines and associated engineering domains. Over a decade, we have helped commercial aircraft companies, engine manufacturers, tier-one suppliers or defence and space market leaders to develop better products faster. pSeven products embedding process automation, design space exploration and predictive modelling capabilities, enables multidisciplinary studies and rapid identification of optimal designs.

Aerospace sector is well known for being one of the most rigorous and regulated market. Engineering activities deal with extremely complex systems sometimes operating in extreme conditions moreover highly constrained by regulation rules. Improving designs in such context requires advanced engineering methods and cutting-edge software solutions to run trade-off analysis in high dimensional space.

Designs obtained thanks to pSeven products are best compromises between conflicting requirements such as: lower fuel consumption or CO2 emissions, reduced noise level, higher performances and, on the other hand, lower maintenance cost or higher operating profits for various mission types. Nowadays, systems complexity and regulations constraints have reached such level that only advanced analytical tools like pSeven products allow engineers to efficiently navigate in the global Design Space and make good design decisions.

Examples of results that can be achieved with pSeven products:

  • Improved fuel consumption and reduced CO2 emissions.
  • Reduced maintenance cost and increased service life.
  • Improved aerodynamic performance.
  • Increased payload and range.
  • Improved safety and lower accident rate.
  • Reduced radar contact and more.

Bi-level airfoil optimization

Determining the airfoil geometry with a maximal range of angles of attack with a positive derivative of the lift coefficient over α - a crucial characteristic for the proper back reaction of the helicopter horizontal tail stabilizer.

Multidisciplinary optimization of UAV structural parameters and flight dynamics

Skoltech student team used pSeven to integrate different simulation tools into a single workflow and to optimize tube-launched UAV characteristics.

Accurate prediction of static and dynamic loads for helicopters

Using predictive models to estimate loads for helicopter components allowed for a drastic reducing of customer expenditures.

Surrogate modeling to speed up structural optimization

Aerospace industry faces the challenge of a time-consuming structure optimization due to noisiness and discontinuity of mechanical strength criteria. Learn how this time was reduced from several days to a few hours using Surrogate-Based Optimization.

Multi-point airfoil shape optimization

The goal to find the airfoil geometry that would provide minimum drag coefficient, satisfying two geometrical and two aerodynamic constraints, is achieved in only 390 evaluations using Surrogate-Based Optimization method.
