Windblast testing

Enhanced Windblast Test Facility

For over 50 years, Dayton T. Brown, Inc. has provided windblast testing services to evaluate aircrew safety during emergency aircraft egress.

The unique capabilities of DTB’s windblast testing system are employed in a few types of specialized tests, as these capabilities are only available in a handful of facilities around the world.

Our windblast facility produces a uniform high velocity air flow field, similar to the aerodynamic environment external to the aircraft. This type of testing is accomplished with the controlled expansion of high pressure compressed air, which exits from a rectangular nozzle. The air from the nozzle impinges upon the test item, which is mounted on the positioning turntable. The dynamic effects are recorded with high-speed video cameras and a data acquisition system for analysis.

Some of the benefits of DTB’s enhanced wind blast facilities:

  • Custom fixture design and fabrication services
  • Large subject flow field — 3 x 5 feet
  • Symmetrical air flow delivery across nozzle assembly
  • High velocity testing designed for peak velocities up to 700 KEAS (knots equivalent air speed)
  • Accurate simulation of ejection aerodynamic conditions
  • High-speed video recording

DTB has tested many types of components and systems:

Aircraft Canopies / Sections • Breathing Systems • Ejection Seats • Flight Clothing
Helmets & Visors • HUD System • Inflation Equipment • Laser Eye Protection
Limb Restraints • NBC Equipment • Night Vision Systems • Oxygen Masks
Retention Systems • RSSK Kits
