Azimuth and Elevation

A brake is used on the actuator to hold the position of the dish.

Leveling Jack Legs

The Power Off Spring Engaged Brake locks legs in place once they are leveled.

Aircraft & UAVs

Gimbal Deployment

A Power-Off Brake helps hold the gimbal depoly actuator in the open or closed position.

Weapons Bay Door Actuation

Weapons Bay Door Actuation

A Power-Off Brake helps hold many utility type actuotors in position, such as a wepons bay door drive.

Flight Control Actuation

Flight Control Actuation

The Power Off Brake helps hold flight control actuators in place, including primary flight control, secondary flight copntrol, leading edge and high lift control actuation systems.

Fighter Jet

Ejection Seat Actuation

Ejection Seat Actuation

A Power Off Brake helps hold the ejection seat in place during flight.

Flight Control Actuation

The Power Off Brake helps hold flight control actuators in place, including primary flight control, secondary flight copntrol, leading edge and high lift control actuation systems.

Utility Actuation

Utility Actuation

A Power Off Brake helps hold utility aircraft actuators in place, including air inlet and weapons bay door drives.

Missile

Control Fin Actuation

Control Fin Actuation

Power Off Spring Engaged Brakes help keep control fins locked in position during captive carry. After the missile is launched, brakes release and fins assist in guiding the missile.

Thrust Vector Control Actuator

A Power-Off Brake helps hold fins in place during launch. During flight, the brake is disengaged and the motors are now in full control of positioning the fins.

Submarine

Valve Control

Valve Control

The Tooth Brake helps hold a valve open or closed until the command is sent to move again.

Radio Antenna Drive System

Powered Tooth Clutches and Tooth Brakes with manual release raise and lower the position of the radar antenna.

Hatch Control Systems

Hatch Control Systems

A Power Off Brake attached to the actuator holds the hatch open or closed.

Tank, Armored Vehicle

Turret Stabilization & Fire Control

Turret Stabilization & Fire Control

A Power Off Clutch allows for manual operation when power fails, providing the warfighter with additional survivability and operational capability.

Ammunition Handling Actuation

Power-On Tooth Clutches are a critical component in many ammunition handling systems for military vehicles.

Challenge

SEPAC engaged with a military aerospace system manufacturer to design and manufacture a high performance tooth clutch for a major attack helicopter platform.

Solution

Due to extreme shock and vibration requirements, as well as harsh environmental conditions, SEPAC’s standard tooth clutch technology had to be adjusted to support new goals. The client’s primary design criteria was a performance profile that would help ensure the safety of the crew and passengers, while delivering 100% mission success.

Production

A robust development program led to prototype testing and ultimately, certification of flight worthiness. New tooth configurations were utilized in conjunction with new combinations of materials and finishes to produce a clutch that currently has a 0% return rate for warranty issues.

Result

SEPAC’s participation in this platform upgrade has allowed our employees, partners and suppliers to proudly share in the results. Documentation from early trials provides evidence that the new model has increased survivability (sevenfold) and lethality (fourfold) as compared to the earlier model.
