LANYARD PULL INITIATOR


 

Single Output

Multiple Output

Used to start a pyotechnic chain of events, a Lanyard Pull Initiator (LPI) incorporates a designated time delay period, once reached attached Explosive Transfer Lines (ETLs) or similar devices are initiated. Pull of the attached lanyard provides mechanical energy to initiate dual percussion primers which start a pyrotechnic chain of events.

Ordnance Time Delay & Booster Charge:  Our LPI’s are supplied with an internal ordnance time delay. Delay time can be tailored to platform specified delay from lanyard pull to detonating output (to allow motor stage separation distance).  If desired, the LPI can be modified for near instantaneous output.  The internal booster charge allows for direct detonation transfer to standard Explosive Transfer Line (ETL) end tips. We offer both single and multiple explosive output Lanyard Pull Initiators and our LPIs require no electrical connections.

We have designed and manufactured 100’s of different LPIs. Qualified and used in various military, commercial and aerospace platforms including aircraft (military and commercial) and multiple missile platforms.
