Supercavitating projectile with reduced-drag control surfaces

Номер: US20120085257A1
Автор: Jyun-Horng Fu
Принадлежит: Lockheed Martin Corp

The illustrative embodiment provides bumpers which are roughly shaped like skis that face towards the air-water boundary of the air cavity. When the projectile fishtails and one or more of the bumpers come into contact with the air-water boundary, the water imparts torque and a rebounding force to push the projectile completely back into the air cavity. Furthermore, because the bumpers are shaped roughly like skis and not like knives, the bumpers do not penetrate the water or create unnecessary water drag.

A fluid working machine has at least one working chamber of cyclically varying volume and low and high pressure valves to regulate the flow of working fluid into and out of the working chamber, from low and high pressure manifolds. The low and high pressure valves are actuated by electronically controlled valve actuation means which, when actuated, applies forces to the low and high pressure valve members to open and/or close the respective valves. The low and high pressure valve members are independently moveable and, although the low pressure valve member typically begins to move quickly in response to a shared valve control signal, the high pressure valve member typically moves only after a change in the pressure within the working chamber. The electronically controlled valve actuation means may be a shared electronically controlled valve actuator, such as a solenoid within a magnetic circuit which directs magnetic flux through both low pressure and high pressure valve armatures which are connected to the respective valve members. 1.

Cartridge with Rapidly Increasing Sequential Ignitions for Guns and Ordnances

Номер: US20130305950A1
Автор: Coffman, II Charles W.
Принадлежит:

A cartridge may be loaded with a powder column containing stratified, stacked layers of propellant, each powder layer over-compressed to a specified degree, with the burn rate controlled by the specified degree of over-compression applied to each respective powder layer. The application of a highly compressed powder column reduces the burn rate, and may force one or more of the powder layers to launch with the projectile down the barrel. Accordingly, the powder column is forced to burn in a manner similar to fuel burning in a solid fuel rocket engine. This greatly reduces the pressure(s) developed in the chamber, and permits the force of the burning powder to be efficiently focused on forward propulsion. The rapidly increasing set of sequential ignitions provides higher and higher energy densities with each subsequent ignition, and creates a more uniform linear acceleration of the projectile for the full length of the target barrel. 1. A propellant charge pellet for use in a cartridge , the pellet comprising:a propellant column comprising stratified stacked layers of propellant, wherein each respective layer of propellant of the stratified stacked layers of propellant is compressed to a specified degree, wherein a respective burn rate of each respective layer of propellant is controlled by the specified degree of compression applied to the respective layer of propellant.2.

Locking Poppet Valve

Номер: US20150020893A1
Автор: Colby Luke S.
Принадлежит:

A locking poppet valve that is reusable and can be pyrotechnically actuated includes an actuating mechanism and a valve assembly that are in fluid communication. A fluid channel traverses through a valve body and fluidly connects the actuating mechanism to a poppet valve positioned within the valve body. When the actuating mechanism is fired, a piston is displaced within an actuator housing, which in turn displaces hydraulic fluid within the actuator housing and the fluid channel. The displaced hydraulic fluid acts to push a valve spool along a valve stem, opening the poppet valve and allowing fluid to flow through the valve body. Additionally, the piston is held in a fired position by a locking mechanism, such that the poppet valve remains open. The poppet valve can be reset by disengaging the locking mechanism and allowing the hydraulic fluid to re-displace within the fluid channel and the actuator housing. 1. A locking poppet valve:a valve assembly;an actuating mechanism;a hydraulic fluid;the valve assembly comprises a valve housing, a fluid channel, and a poppet valve;the actuating mechanism comprises an actuator housing, a piston, and a locking mechanism;the piston comprises a locking rod and a actuator spool;the actuator housing being adjacently connected to the valve housing;the poppet valve being connected to the valve housing;the poppet valve being positioned within the valve housing;the fluid channel traversing through the valve housing;the actuator housing being in fluid communication with the poppet valve through the fluid channel;the actuator housing and the fluid channel being filled with the hydraulic fluid;the locking mechanism being mechanically coupled to the actuator housing;the piston being slidably positioned within the actuator housing;the piston being positioned adjacent to the locking mechanism; andthe actuator spool being concentrically connected to the locking rod opposite the locking mechanism.2.
