The instant application discloses, among other things, devices and techniques for using high-intensity focused ultrasound (HIFU) for detonation of explosives. In one embodiment, a device configured to hold small, disposable, ultrasonic transducer arrays suitable for disposal, detonation, or other manipulation of explosives and hazardous materials is provided.
摘要:
The invention relates to a pyrotechnic gas generator component including an inlet stage formed by a pyrotechnic detonator composition and an intermediate stage disposed between the inlet stage and an outlet stage formed by at least one gas generator composition, said intermediate stage being formed by a compressed black powder layer.
摘要:
A method of irradiating a target region containing at least one fullerene comprising molecule promotes the heating or combustion of the target region. The heating method can be employed in a variety of applications including: selective targeting and destruction of cancer cells, detonation of explosives, ignition of a combustible mixture, photolithographic processes, and writing of optical storage media.
摘要:
A catalyst free method of igniting an ionic liquid is provided. The method can include mixing a liquid hypergol with a HAN-based ionic liquid to ignite the HAN-based ionic liquid in the absence of a catalyst. The HAN-based ionic liquid and the liquid hypergol can be injected into a combustion chamber. The HAN-based ionic liquid and the liquid hypergol can impinge upon a stagnation plate positioned at top portion of the combustion chamber.
摘要:
A method of making a thin film explosive detonator includes forming a substrate layer; depositing a metal layer in situ on the substrate layer; and reacting the metal layer to form a primary explosive layer. The method and apparatus formed thereby integrates fabrication of a micro-detonator in a monolithic MEMS structure using “in-situ” production of the explosive material within the apparatus, in sizes with linear dimensions below about 1 mm. The method is applicable to high-volume low-cost manufacturing of MEMS safety-and-arming devices. The apparatus can be initiated either electrically or mechanically at either a single point or multiple points, using energies of less than about 1 mJ.
摘要:
The invention relates to thermal pre-ignition agents and to their use as thermal fuses, in particular for use in gas generators of motor-vehicle safety systems.
摘要:
An ETC igniter and compatible electrical connector for enabling an ETC gun to be used in a battlefield setting in close proximity with personnel and sensitive electronic equipment. This is accomplished by providing a current path to and from the igniter that is electrically isolated from all other portions of the gun. The connector and igniter are adapted to be capable of withstanding the high connection forces necessary to prevent arcing and the extreme stresses imposed during firing of the gun.
摘要:
A single increment initiator charge for use in an inflatable restraint system and a method of preparing the single increment initiator charge are provided. The single increment initiator charge includes a homogeneous blend of zirconium, an oxidizer such as potassium perchlorate, and a combustion enhancer such as titanium hydride in an amount effective to result in the single increment initiator charge being effective to ignite an associated pyrotechnic charge. The single increment initiator charge may be formed by preparing a homogeneous blend such as by dry-blending the constituents or by mixing the constituents with a solvent such as an alcohol to form a slurry, loading the homogeneous blend into a charge holder and compressing the homogeneous blend.
摘要:
A solid pyrotechnic composition having a flame temperature and exhibiting ballistic performance comparable to that of black powder, but which does not contain charcoal or sulfur, is provided, as is a method for making such composition. A solid pyrotechnic composition, and method for making the same, which has a flame temperature and exhibits ballistic performance comparable to that of boron/potassium nitrate and that is preferably free of boron is also provided.
摘要:
An igniter composition for a gas generant and related methods of gas generation are provided in which, in addition to a boron fuel component and an oxidizer component, the igniter composition additionally includes a gas-producing fuel component.
