A spring damper system for a pyrotechnic time delay may comprise: a piston; a firing pin; a hydraulic chamber, a portion of the piston disposed in the hydraulic chamber; and a first spring configured to compress in response to a time delay sequence being initiated, the piston configured to translate axially in the first axial direction in response to the first spring returning axially towards a neutral state, the first engagement end and the second engagement end configured to release in response to exiting the channel, and the firing pin configured to translate in the second axial direction in response to a second spring returning towards a second neutral state.

Time delay systems, methods, and devices

A damper system for a pyrotechnic time delay may comprise: a firing pin; a moveable housing defining a chamber therein; a fixed piston comprising a piston head disposed in the chamber, a first rod extending from the piston head axially outward of the moveable housing, and a second rod configured to fixedly couple to a housing; a first spring extending axially from the moveable housing to the firing pin; and a second spring extending axially from the moveable housing to the firing pin.

A high energy catapult assembly may comprise an outer tube and an inner tube located within the outer tube. The outer tube may be configured to telescope relative to the inner tube. A propellant cartridge may be located in an inner tube chamber of the inner tube. An actuator may be configured to change an open volume of the inner tube chamber.

Variable volume high energy catapult assemblies for ejection systems

A rocket catapult assembly for an ejection seat may comprise a motor assembly including a proximal end and a distal end, a first cartridge, and a second cartridge. The first cartridge and the second cartridge may be configured to provide a variable thrust based on an occupant's weight. The first cartridge may provide a thrust corresponding to a relatively light weight occupant, the second cartridge may provide a thrust corresponding to a relatively average weight occupant, and the first cartridge and second cartridge may provide a combined thrust corresponding to a relatively heavy weight occupant.

Variable thrust catapult

An ejection seat for an aircraft is disclosed. In various embodiments, the ejection seat includes a seat frame; and a moveable headrest attached to the seat frame, the moveable headrest including a first piercer assembly configured for fracturing a canopy.

Passive head and neck protection canopy piercer

A severance cutter may comprise a housing and a blade may be coupled to the housing. A restraint support may be configured to translate relative to the blade. A spring may be configured to bias a support opening defined by the restraint support away from the blade.

Adjustable preload severance cutter for ejection systems

A rocket catapult assembly for an ejection seat may comprise a drive motor, a metering tube, a first cartridge, and a second cartridge. The metering tube may include an outer wall having a gas pervious section and a gas impervious section. The drive motor may be configured to translate the metering tube and align the gas pervious section or gas impervious section with a first cartridge and a second cartridge to produce a desired thrust of the rocket catapult assembly.

A rocket catapult assembly for an ejection seat may comprise a motor assembly including a proximal end and a distal end, an outlet tube coupled to the distal end, and a valve coupled to the outlet tube. The valve may be configured to vary an operating pressure based on an occupant's weight. The valve may be in a closed configuration, on open configuration, or a partially open configuration during ejection of the ejection seat.

An adjustable leg restraint for an ejection seat may be configured to translate between an extended state and a nonextended state. The adjustable leg restraint may include a leg located proximate a side panel of the ejection seat. An extension flange may be coupled to the leg guard. The extension flange may be configured to translate the leg guard relative to the side panel of the ejection seat.

Adjustable leg restraints for ejection seats

An occupant camera system for an aircraft ejection assembly may comprise a fixed structure and a camera mounted to the fixed structure. A digital video recorder may be mounted to the fixed structure and electrically coupled to the camera. A switch may be electrically coupled to the digital video recorder, and a battery may be electrically coupled to the switch.

Ejection seat occupant camera system

An energetic ignition arrangement may comprise a pressure vessel arrangement, comprising a pressure vessel, and an ignition system arrangement. The ignition system arrangement may comprise an ignitor housing coupled to the pressure vessel and defining a sealing aperture, a seal disposed in the sealing aperture, and an electric match extending through the ignitor housing, wherein at least the ignitor housing and the pressure vessel are reusable after the energetic ignition arrangement has been employed in an ignition event.

Reusable high pressure and high temperature energetic ignition system

A method of sequencing a pyrotechnic system includes igniting at least one of a first energetic coupled to a first inlet of a one way sequence termination arrangement, and a second energetic coupled to a second inlet of the one way sequence termination arrangement, fluidically coupling the first inlet to an outlet of the one way sequence termination arrangement in response to the second energetic being ignited before the first energetic is ignited, and blocking fluidic coupling between the second inlet and the outlet in response to the first energetic being ignited before the second energetic is ignited.

Energetic one way sequence termination valve

An energetic one way sequence termination arrangement may comprise a housing, a first inlet in operable communication with the housing, a second inlet in operable communication with the housing, and an outlet in operable communication with the housing. The energetic one way sequence termination arrangement is configured such that the second inlet is blocked from fluidic communication with the outlet in response to a first signal being received at the first inlet before a second signal is received at the second inlet, and the first inlet establishes fluidic communication with the outlet in response to the second signal being received at the second inlet before the first signal is received at the first inlet.
