CS Inc[edit]

CS Communication And Systems Inc was established in 2015 in East Hartford, CT to work with clients based in the United States. This is the company's first US branch and since its conception, it has secured several clients including Pratt & Whitney and Triumph Engine Controls. The US branch now employs over 25 people including software engineers, design engineers and IPT leads who mainly work on Aircraft Engine design and Software Testing in accordance with DO-178B. CS Inc. has worked on several commercial engines including the PW1100 for the Airbus A320 Neo, PW1500 for the Bombardier CS series and the PW1900 for the Embraer E-jets. More recent projects include military engines as well for which the company has formed a new military division.

Other activities[edit]

CS develops a computational fluid dynamics software solution based on the Lattice-Boltzmann method :ProLB. Low dissipation and dispersion errors combined with state-of-the-art turbulence modeling approaches (Large Eddy Simulations), allow ProLB to perform high-fidelity aeroacoustic and aerodynamic simulations of weakly compressible flows.

Intelligent transportation[edit]

CS provides toll-road equipment and back-office systems, integrated to ensure toll collection and customer management:[7][8]

  • Conventional and electronic toll collection
  • Free-flow systems: Open-road tolling (including enforcement and an integrated back office)
  • Emergency call boxes
  • Urban transportation-information systems
