Product Application Descriptions


PC Power Cartridges, Squibs & Initiators

Hi-Shear is the primary qualified source for the NASA Standard Initiator (NSI) used for all initiation functions on the Space Shuttle. The NSI performs from an incredible low temperature of −420°F to a high of +320°F. Only NASA now distributes the NSI. However, the NSI "equivalent" alternative is our PC-23 initiator. It is utilized in all non-NASA space and major defense programs where the NSI was previously used. Our PC series meet Range Safety Standards for RF & EMI hazards, and 5 minutes 1 Amp / 1 Watt No-Fire test. The PC 117 series meets MIL-DTL-23659.

Applications:

Separation systems
Electrical disconnects
Explosive switches and valves
Parachute and data package ejection system
Rocket motor ignition systems
Any application requiring rapid gas & heat generation

PD Detonator

Hi-Shear is the primary qualified source for the NASA Standard Detonator (NSD) used for all detonating functions on the Space Shuttle. The NSD is a combined NASA Standard Initiator (NSI) with a hermetically sealed Detonating Module. Hi-Shear detonators are designed to transfer shock waves and high pressure energies for initiating detonating trains, Shielded Mild Detonating Cord (SMDC) Flexible Confined Detonating Cord (FCDC) and other linear explosive lines. The PD Series function with 99.99% reliability at 95% confidence level from −165°F to +225°F and at altitudes to 420,000 feet. The PD series meets Range Safety Standards for RF & EMI hazards, and 5 minutes 1 Amp / 1 Watt No-Fire test.

Applications:

Actuation
Missile & Spacecraft Stage Separation
Range Safety Destruct
Severance or Separation
Demolition
Any application requiring detonating actuation.

SN Separation Nuts

General features are lightweight, high-load capability, ultra low shock output with complete gas and particle containment. These pyrotechnic nuts actuate on very low pressure with large bolt insertion tolerance. Re-settable option is available.

Applications:

Separations or release of structure (or components) such as multi-stage launch vehicles, fairings, payload hold-down & release
Separation of nose cones and capsules
Separation of underwater devices and ejection seats
Release of booster rockets, tanks and other jettison equipment

SN Non-Pyro Separation Nuts

Extreme low shock output non-pyro separation nut. These nuts are actuated by a miniature electric motor on low energy with large bolt insertion tolerance. Re-settable option is available.

These nuts are used in:

Separations or release of structure (or components) such as multi-stage launch vehicles
Separation of nose cones and capsules
Separation of underwater devices and ejection seats
Release of booster rockets, tanks and other jettison equipment

SH Bolt Catchers & Bolt Retractors

Bolt catchers and improved bolt retractors are designed to retain (extract) a tension bolt after separation. They prevent potential structural damage or component malfunction due to bolt ejection. These devices are specifically designed for use in conjunction with Hi-Shear Separation Nuts as standard hardware for separation systems.


SL Cutters (cable, rod and reefing line)

Cutters designed for robustness are used in deep space as well as deep submergence applications.

Used for rapid severance of:

Electrical cables
Steel cables
Aluminum, titanium and steel bolts
Aluminum, titanium and steel rods
Wire bundles
Reefing lines

SF Thrusters

Thrusters range from miniature type measuring less than ¼ inch diameter & 1 inch long to over 2 inchs diameter and 9½ inches long. These devices are capable of exerting forces from less than 1 pound to more than 12,000 pounds.

Applications:

Ejection, jettison or separation of structures
Ejection of aircrew capsules
Remove missile launch covers or radar lens protectors
Eject instrument packages & parachute canisters from re-entry vehicles

SP Pin Pullers & Pin Pushers

Pin Pullers are controlled release mechanisms for instant detachment of structural fittings, mechanisms, packages, rods, cables or parachutes.


TBI

Thru Bulkhead Initiators


These devices transfer detonating energy from linear explosive lines through the bulkhead into heat and gas output. Typical applications are similar to PC Series initiators .

SB Separation & Explosive Bolts

Separation Bolts series are designed and manufactured for use in launch vehicles, weapon systems, aircraft and other applications where rapid structure separation is demanded. Also known as explosive bolts, this product can handle tension load capabilities are in excess of 500,000 pounds.


ESAF & FTS Electronic Safe Arm Fuze & Flight Termination System Devices

Electronic Safe Arm Fuze (ESAF) is a dual mode, in-line system MIL-STD-1316 qualified single channel, fully electronic safe arm fuze with a removable keylock slapper detonator (EFI) assembly. Its function is to preclude premature arming and consequent initiation of the detonator during transportation, handling, pre-launch and launch conditions. When commanded, it also functions as a flight termination (missile destruct) during missile fly out.


SJ Gas Generators

Gas generators drive many functions on missiles, fighter aircraft, launch vehicles and satellites. Hi-Shear PC series initiators are used to function these gas generator devices.


PE

Exploding Bridgewire (EBW) Initiators & Detonators


EBW initiators & detonators are used with our EBW firing units and cable assemblies.

These devices typically actuate:

Separation systems
Explosive switches and valves
Parachute and data package ejection systems
Rocket motor & warhead ignition
Any application requiring gas generating or detonating output

EFI

Exploding Foil Initiators

EFI is similar to EBW except that an exploding foil bridge is used to accelerate a flyer down the barrel to impact an insensitive secondary explosive.

Meets MIL-STD-1316 & functioned by the Hi-Shear ESAF
