7 results about "Reaction control system" patented technology

A reaction control system (RCS) is a spacecraft system that uses thrusters to provide attitude control, and sometimes translation. Use of diverted engine thrust to provide stable attitude control of a short-or-vertical takeoff and landing aircraft below conventional winged flight speeds, such as with the Harrier "jump jet", may also be referred to as a reaction control system.

A multi-chamber plasma experimental system based on uniform electrode distance adjustment

PendingCN122273443AControl systemPlasma reaction
This application relates to the field of plasma reaction devices and discloses a multi-chamber plasma experimental system based on unified electrode spacing adjustment. The system includes a first plastic plate, with uniformly distributed reaction vessels fixedly connected to the top of the first plastic plate. Telescopic vessels are slidably connected to the inner diameter of each reaction vessel, and second plastic plates are fixedly connected to the top of each telescopic vessel. A sample inlet is fixedly connected to the bottom of each reaction vessel, penetrating the first plastic plate. The system also includes a reaction control system comprising an inlet control module, a sample inlet control module, and a metal plate distance control module. The distance between the second and first plastic plates is adjusted via the metal plate distance control module, thereby adjusting the position of the metal plates and thus the discharge spacing. Real-time control of various reaction conditions in each reaction vessel allows for simultaneous degradation experiments of the same pollutant under different conditions, facilitating control experiments.

Reusable Launch Vehicle with Auxiliary Propellant Tanks for Non-Ascent Burns

PendingUS20260184441A1Control systemFuel tank
A reusable launch vehicle comprising auxiliary tanks for non-ascent burns, such as orbital maneuver burns, reorientation burns, deorbit burns, or landing burns, and / or power generation. The auxiliary tanks may provide propellants for an orbital maneuvering system, an orbital reaction control system, a reentry reaction control system, and / or a power generation system. The tanks are configured to maintain cryogenic properties of auxiliary fuel and auxiliary oxidizer for the duration of the mission. An auxiliary fuel tank, a main fuel tank, an auxiliary oxidizer tank, and a main oxidizer tank may have various relative positions with respect to each other within the launch vehicle. The auxiliary fuel tank and auxiliary oxidizer tank may comprise insulation to further insulate the cryogenic fluids.

Polymer ring-opening polymerization control system based on high viscosity rheology control

This invention discloses a polymer ring-opening polymerization reaction control system based on high-viscosity rheological control, relating to the field of high-viscosity polymerization control technology, and specifically to the reaction control of the high-viscosity final stage of ring-opening polymerization of medical absorbable polymers PPDO or PGLA. A micro-bypass rheological measurement loop is installed alongside the main process to periodically collect fast variables and obtain reference viscosity point, shear consistency index, differential pressure drift, response time, and other health indicators. The bypass is isolated in case of abnormalities. Based on fast variable prediction and combined with health indicator calculations, a confidence weight is performed, and gated correction and parameter updates are executed, outputting a quality status estimate and reliable / suspicious / unusable tags. Trajectory control is performed under constraints such as temperature, torque, and differential pressure, with incremental control limited by tags. A degradation-cleaning-recovery state machine is triggered and an event log is recorded. This scheme can suppress false signal-driven processes, reduce the risk of deviation and loss of control, improve batch pass rate and closed-loop availability, and support continuous production traceability and operation and maintenance management.

A reaction control system for automated NGS library construction

PendingCN122303026AMolecular diagnostic techniquesMolecular diagnostics
This invention belongs to the field of molecular diagnostics technology, and particularly relates to a reaction control system for automated NGS library construction. The system includes a base plate, a motion module, a top plate, a nucleic acid extraction module, a nucleic acid fragmentation module, a first driving component, a library amplification module, and a processor. The motion module is mounted on the base plate, and the top plate is directly or indirectly connected to the motion end of the motion module. Multiple first driving components are disposed on the top plate. The motion module and the first driving components can move the nucleic acid extraction module and the nucleic acid fragmentation module relative to the base plate in different directions to drive them to engage with corresponding reaction wells. The library amplification module is disposed on the base plate and provides the required temperature for the amplification reaction to the corresponding reaction wells. This invention, in conjunction with a reaction apparatus, can automate NGS library construction. The modular design facilitates adjustment, and the library amplification module's heat dissipation accelerates cooling and shortens reaction time.
