How to Make Low Flow Measurements Using Turbine Flow Meters

Accurate low flow measurement represents significant challenges in many applications. Some typical low flow applications in the aerospace market include: small UAV fuel consumption, satellite thruster fuel consumption, and fuel/chemical/water injection. The low dynamic energy associated with flow rates down to 0.001 GPM exceed the capabilities of most mechanical flow meters and force the use of less accurate flow meter technologies.

Neutralizing Nature: Controlling the Environment in Aerospace

If your goal is to send a billion-dollar satellite into space or to maintain precision defense systems aboard aircraft tasked with defending the nation, environmental variations aren't so much the spice of life as an endless minefield of potential hazards that could destroy your mission. In the unforgiving aerospace sector, the idea is not to celebrate nature but to neutralize it, creating artificial environments that remain precisely clean and stable, wherever the equipment or payload you're assembling, transporting and sending aloft happens to be.

Achieving Reliable Inline Measurements in Production Environments

One of the most important changes in metrology in the past few decades has been the development of portable measuring devices. This has brought inspection right to the production line, as close to the part as possible. The change—sparked by the development of portable measuring arms and the emergence of laser trackers—has turned conventional industry inspection methods completely upside down.

New GASOMETER Design Uses Active Accommodation Offering Significant Improvements Vs. Liquid-sealed Methods

Active Accommodation means using a precision controlled and driven cylinder/piston assembly to collect and measure gas sample volumes without requiring energy to be extracted from the process that generates the gas. The mechanism uses lubricated O-Rings to seal the measuring chamber unlike classical Wet Test Meters that require a water or oil bath to produce an isolation seal.

Developing and Testing Electronic Control Units for Electric Drives

Air framers are looking to build more eco-friendly and economical aircraft, and they are turning to electric drives. One growing trend is to build more electrical aircraft by replacing pneumatic and hydraulic systems with electric actuators. Electric drives, therefore, will play an important role in the aircraft of the future. This paper examines the current state of technology for developing and testing electric drives.

AGM Thumbtack™ Valves for Small Enclosures: Smaller and Drier

Sensitive equipment such as optics and electronics can be damaged by humidity and condensation. Placing moisture-sensitive equipment inside a sealed enclosure reduces the risk of damage, but temperature and pressure variations can be problematic for a sealed enclosure if it does not have a pressure-relief mechanism.
