  • Patent number: 10309346
    Abstract: A cylindrically-shaped hybrid rocket engine solid fuel grain defines an axial combustion port. A fuel grain material comprises a compounded blend of thermoplastic fuel and aluminum. The fuel grain comprises fused stack layers, each layer comprising a plurality of fused abutting concentric beaded structures arrayed to define the combustion port; the port exhibits a rifling pattern or rifling inducing geometry along the port wall. When an oxidizer is introduced into the combustion port combustion occurs along the exposed port wall. Each beaded structure defines a geometry that increases the combustion surface area while inducing a vortex flow of oxidizer and fuel gas. As each layer ablates, an abutting layer exhibiting a similar geometry, is revealed, undergoes a gas phase change, and ablates. This process repeats and persists until oxidizer flow is terminated or the fuel grain material is exhausted. The fuel grain may be manufactured by an additive manufacturing process.

  • Patent number: 10286599
    Abstract: A hybrid rocket solid fuel grain having a cylindrical shape and defining a center port is additive manufactured from a compound of thermoplastic fuel and passivated nanocomposite aluminum additive. The fuel grain comprises a stack of fused layers, each layer formed as a plurality of fused abutting concentric circular beaded structures arrayed to define a center port. During operation, an oxidizer is introduced along the center port, with combustion occurring along the exposed port wall. Each circular beaded structure defines geometry that increases the surface area available for combustion. As each layer ablates the next abutting layer, exhibiting a similar geometry, is revealed, undergoes a gas phase change, and ablates. This process repeats and persists until oxidizer flow is terminated or the fuel grain material is exhausted. To safely achieve this construction, a fused deposition additive manufacturing apparatus, modified to shield the nanocomposite material from the atmosphere, is used.

  • Patent number: 9890091
    Abstract: An additively manufactured solid fuel grain for a hybrid rocket engine having a cylindrical shape, defining a center combustion port and comprising a stack of fused layers of polymeric material suitable for hybrid rocket fuel. Each layer is formed as a plurality of fused abutting concentric beads of solidified material arrayed around the center port. An oxidizer is introduced into the solid fuel grain through the center port, with combustion occurring along the exposed surface area of the solid fuel grain center port wall. Each concentric bead possesses a surface pattern that increases the combustion surface area and when stacked forms a rifling pattern of undulations that induces oxidizer-fuel gas axial flow to improve combustion efficiency. The port wall surface pattern persists during the rocket engine's operation as the fuel phase changes from solid to gas and is ablated.

  • Patent number: 9822045
    Abstract: A hybrid rocket solid fuel grain having a cylindrical shape and defining a center port is additive manufactured from a compound of thermoplastic fuel and passivated nanocomposite aluminum additive. The fuel grain comprises a stack of fused layers, each formed as a plurality of fused abutting concentric circular beaded structures of different radii arrayed defining a center port. During operation, an oxidizer is introduced along the center port, with combustion occurring along the exposed port wall. Each circular beaded structure possesses geometry that increases the surface area available for combustion. As each layer ablates the next abutting layer, exhibiting a similar geometry is revealed, undergoes a gas phase change, and ablates.

  • Patent number: 9453479
    Abstract: A solid fuel grain suitable for use in hybrid propulsion systems has a generally cylindrical shape and defines a center port. The solid fuel grain is formed as a series of concentric layers arrayed around the center port. When incorporated into a rocket, an oxidizer is introduced into the solid fuel grain along a pathway defined by the center port, with combustion occurring along the exposed surface area of the solid fuel grain section adjacent to the center port. Each concentric layer has a surface pattern that serves to increase the surface area for combustion, a surface pattern that persists even as the fuel burns. To achieve such a construction, the concentric layers of the solid fuel grain are preferably manufactured using any one of several available freeform-fabrication machines capable of fabricating articles in a polymeric material suitable for a hybrid propulsion system.

  • Patent number: 6584631
    Abstract: A support pillow for maintaining a hairstyle is provided which allows one to maintain his or her hairstyle while sleeping. The support pillow has a flexible cushion supported by a plastic shell stabilizer. The cushion includes a base portion which supports a toroidal portion. An oval-shaped cavity separates upper and lower circumferential edges of the toroidal portion. The oval-shaped cavity houses a domed protuberant. The toroidal portion bifurcates into a pair of downwardly directed offshoot members which merge into a bulbous portion, thereby forming a generally triangular-shaped opening which provides entrance to a hollow cavity. The hollow cavity accommodates a removable, fluffed pillow. An overlay conforms to an outer surface of the cushion and shell stabilizer.

  • Patent number: 5824880
    Abstract: A test fixture of the type that requires repeated manual lifting of weights in a drop-tube for performing an ASTM drop weight test, is provided with a computer automated pneumatically powered lift mechanism. The lift mechanism for the weights responds to a series of computer generated signals that are applied to a set of electropneumatic actuators for driving pistons to lift and drop the weight. Associated with the lift mechanism is a set opto-interrupter devices that generate a position signal representative of the position of the weight to be dropped as it ascends in the drop tube. In use the computer is provided with a desired drop height and essentially continuously compares the position signal with the desired drop height and releases the weight in the drop tube to impact a sample material when the position signal equals the desired drop height.
