摘要:
Components (10) can comprise a substrate (11), a strain sensor (40) comprising at least two reference points (41,42) disposed on the substrate (11), and one or more thermally reactive features (50) disposed on the substrate (11) proximate the strain sensor (40), wherein the one or more thermally reactive features (50) react to one or more elevated temperatures.
摘要:
A solid propellant rocket motor has a tubular casing accommodating a mass of solid propellant material and at least one opening for the space in the casing to communicate with the outside closed by a closing head; the closing head being coupled to the casing by means of one or the other of two blocking portions with different strength both carried by a movement device which can be elastically deformed and operated from the outside.
摘要:
The invention relates to modular solid-fuel rocket propelling charges comprising different propellant components and other components, for example, fuels, oxidators, energy increasing admixtures, binders, additives, coatings, inhibitors, etc. which can be completely or partially fragmented, i.e. they are not provided in the form of the conventional quasi homogeneous mixture, rather they are available in the form of one or more macroscopic combustible elements having any appropriate configuration. All or individual components can also be comprised of substances which must first be sufficiently brought to a solid state by cooling. The aim of the invention is to provide modular solid-fuel rocket propelling charges of the aforementioned type such that the development of dangerous situations resulting from a cooling failure during simultaneous power increases of the carrier rockets is drastically minimized. To this end, the modules are provided as an assembly or the individual combustible elements thereof are provided with a special casing (1). Said special casing permits the storage of such propelling charges and/or the operation thereof according to prescription in such a way that problems do not occur due to the dependence on temperature of the mechanical characteristics or of the state of the aggregate.

Un bloc de poudre (11) est logé dans une enveloppe (10) avec interposition d'une protection thermique (12) et délimite une chambre de combustion (13), un décollement (15, 20) est formé entre le bloc de poudre (11) et le revêtement (17, 22) de protection thermique de la structure de fond du propulseur au moyen d'une peau (16, 21) décollée dudit revêtement et adhérant au bloc de poudre, au moins une des deux parties que constituent la peau décollée (16, 21) et le revêtement (17, 22) de protection thermique de la structure de fond du propulseur présentant des protubérances ou picots (18, 23)) pour assurer un écartement minimum de la peau décollée par rapport audit revêtement et faciliter l'accès des gaz dans le décollement (15, 20).
摘要:
There is disclosed a solid fuel rocket motor (500) which may include a case (510) and a nozzle (540) coupled to the case. A plurality of fuel pellets (525) may be disposed within the case. An igniter (550) may be disposed to ignite at least a portion of the fuel pellets. A pellet retainer (535) may be positioned within the case to retain the plurality of fuel pellets within the case. The pellet retainer may be perforated to allow exhaust gases to flow from the ignited fuel pellets to the nozzle while preventing unburned fuel pellets from being expelled through the nozzle.
