Latching Mechanism

Latch Status

• Easily identifiable latch status

Device Testing Example

Testing 90mm PostPak with short device @600 Psi

Photographic example of the implementation of the device

Theoretical Parameters

Virtues of System(in comparison to standard Pyros)

Safety:Less sensitive to sparks & electromagnetic spikesNo hazardous temperatures generated or requiredNon-instant activation delays

Preparation:Faster and easier preparation than pyrosLess chance of damaging critical expendable parts (eg. Ematch installation)Less anxiety for the preparation (once you’re familiarized with it)

Reliability:No expendable pyrotechnic devices to be connected and installedOption for thorough ground testing reusable device to reduce or eliminate the requirement for redundancy

Regulatory:No hazardous or dangerous or regulated parts requiredPotentially less compliance work required for projects/facilities that require stringent requirements for pyrotechnic devices eg, government/defence operated ranges.

General Virtues

• Low power actuation (can operate on 1 AAA battery)

• Wide operating voltage range (1.5V – 12V)• 1st 2 points renders it directly compatible with all

the available flight electronics systems.• Minimal increased footprint from pyro canisters• Modest weight increase for larger rockets• Easy mounting points• High Discharge Rate - Instant Discharge FAIAP

• Quick(ish) response time

Disadvantages over Standard BP Pyros

• Is a larger & heavier unit

• Complex device – Higher production costs
