Key features

Long experience of developing control computers and actuation systems for commercial and military aircraft.
Full responsibility from study/definition phase through specification, development, verification/qualification, production and customer support
Available as an integral part of a higher level system such as a load bearing door or hatch

Utility Control Systems

Our offering within Utility Control Systems is wide and includes full system responsibility. Saab can offer a complete solution, including the door structure as well as the door actuation system and associated control electronics. It is designed and optimized on system level for high reliability, low weight and cost-efficiency.

Key Capabilities

  • Full responsibility from study/definition phase through specification, development, verification/qualification, production and customer support
  • Complete in-house development, both HW and SW (incl. application SW)
  • In-depth application knowledge within Cargo Door Actuation Systems
  • Safety critical control computers yet with high level of integrated platform functionality, examples:
    • ARINC standard dataloader
    • AFDX
    • Extensive Built-In Tests (PBIT, CBIT and IBIT)
    • RTOS (ARINC653)

Key Elements

Rapid prototyping, short lead time to first equipment with full functional compliance

  • RTCA DO-178/254 DAL A compliant
  • RTCA DO-160 compliant (environmental)
  • Highly reliable and efficient electric actuation systems
  • High integrity control electronics based on a Modular Computer Design

Door Actuation Systems

Saab Avionics Systems are developing integrated door solutions together with Saab Aerostructures. Example of applications:

Cargo Door Actuation Systems

We offer state-of-the-art electromechanical cargo door actuation systems optimized for high reliability, low weight and cost efficiency. The actuation systems are based on our EMA product platform that includes rotary or linear actuation according to customer requirements.

Over Wing Exit Door Flight Lock Actuator

The Over Wing Exit Door Flight Lock Actuator not only locks the door handle bar during certain flight phases but also ensures the structural integrity of the fuselage.

Landing Gear and Brake Control Systems

Based on our electromechanical actuation platform and our safety critical control computer platform Saab can deliver cost-efficient solutions for e.g. landing gear extend/retract and brake control adapted to customer-specific needs.

Did you know...

  • Avionics Systems have before (finished in 2016) developed a full scale Cargo Door Demonstrator partly funded through Vinnova program GF-Demo.
  • This demonstrator was jointly developed with Saab Aerostructures to demonstrate the unique Saab capability of an integrated cargo door solution – composite structure with integrated electromechanical control system.
80
Saab’s flight control and actuation systems are based on more than 80 years’ experience, both as an aircraft OEM and system supplier. We understand our customers; we know how to build aircraft.
