Characterize and test mission-critical aerospace and defense components

Use direct process inputs to control dome-loaded pressure regulators with high accuracy and repeatability. Advanced pressure controllers, mass flow meters, and mass flow controllers improve process control from initial R&D through test benches for mission critical components in a range of applications:

  • Leak testing valves for capsule engines
  • Satellite altitude control
  • Liquid cooling systems for pressure suits and engine systems
  • Gas mixing to emulate exotic atmospheres
  • Buoyancy testing requiring accurate totalizing and dosing
  • Breathing simulations

Control flow instruments directly using process pressures

Use the PC-EXTSEN pressure controller to send a voltage signal directly from a 20,000 PSI transducer to an Alicat piloting a dome-loaded pressure regulator. Controlling using actual process pressure improves response times and minimizes fluctuations.

Standardize devices to your system parameters and setup

Devices are preconfigured with your choice of STP/NTP conditions and engineering units, and are easily adjustable in the field without requiring recalibration.

AS5202 porting and easy-to-use electronics ensure simple integration with standard NASA and other test bench equipment.

The responsive, data-rich display on any Alicat enables you to easily monitor the health of your process.

Leak testing and characterizing mission-critical systems

Direct pneumatic pressure controllers at 3,000 PSI are ideal for leak testing and characterizing thrust-producing flow components like throttle plates.

Argon or nitrogen can be used as surrogate gases for testing, with flow and pressure controllers easily able to switch between flowing different gases.

High pressure fluid delivery and control

Alicat pressure controllers operate up to 3,000 PSI, making them well-suited for torch control systems emulating conditions in space.

Vacuum controllers hold setpoints even with rapidly changing process and ambient conditions.

Solutions for high flow/high pressure testing

Valves often limit flow rates at high pressures. To overcome this, pressurize a chamber with a solenoid valve and maintain pressure using hammerhead valves. This shortens response time and enhances reproducibility of hypersonic wind tunnel experiments.

Instrumentation in aerospace and defense research

Alicat instrumentation is used in research focused on emerging technologies in the aerospace and defense industry.

This research is exploring topics such as film cooling, evaluation of a disk-shaper pressure gain combustor, and metal additive manufacturing of an offset strip fin.
