LOUGHBOROUGH, UK -- Magna Parva Ltd., the provider of engineering solutions for extreme environments, is showing for the first time its R3™ Restraint and Release Mechanism - intended to satisfy stringent requirements such as those found in military applications.
The R3 design offers a long list of impressive features including high reliability, low mass and lower power operation and is highly versatile in operation. It can be used as a primary release mechanism, where the device to be released has an engagement pin inbuilt, or as a secondary release mechanism or ‘pin puller’.
With a high force capability of 15N to 30,000N depending on size and configuration of the unit, applications include equipment release from aircraft in flight, and military vehicle equipment deployment.
Other features of the device include: microsecond response times, vibration tolerance to 2000g acceleration, radiation tolerance, wide temperature and humidity tolerance and vacuum compatibility. The device’s electrical characteristics are designed to meet TEMPEST requirements. Power consumption in operation is just a few microwatts.
Unlike some alternative systems such as percussive devices, the R3 mechanism is reusable for many cycles, and emits no volatile material during operation.
Design of the R3 Restraint and Release Mechanism is an excellent example of how Magna Parva is taking technology developed for one sector - such as space - and using the lessons learned to produce innovative approaches to problems in other fields.
Magna Parva has not yet disclosed details of the construction of its new device, but is ready to talk in detail with manufacturers, system developers and users about potential applications.
“This new restraint and release mechanism has a very wide envelope of operation and should see application in lots of critical situations”, says Andrew Bowyer, Director at Magna Parva. “We’d be delighted to demonstrate the device, and to discuss possible uses with interested organisations.”
