StratSat provides a geo-stationary platform at 20 km altitude capable of remaining on-station for up to five years. Payloads include high speed Internet services, direct broadcast TV, mobile telecommunication, etc. The envelope operates as a super-pressure hull(i. e. with no ballonet pressure control system). The hull will be of laminated fabric construction with Tedlar/Teflon, helium/weather barrier developed from AT-10/04. Multiple catenary curtain system supporting a payload module enclosed completely by the envelope. [The] payload module... comprises a single structural module with an externally mounted payload/mission system. The payload module provides a home for all of the airship's primary systems except for the propulsion system. The systems are close packed within the highly insulated module ensuring efficient heat and energy management. The payload module is pendulum stabilised within the envelope. The solar array provides the sole source of renewable energy for the airship. The array is placed over the upper quarter of the hull and extends over approximately three-quarters of the length of the craft. The array can be realigned to the daily sun location/angle by the roll rotation of the whole airship. The energy collected by the solar array is stored for use during the night in the series of batteries. Located in the stored for use during the night in a series of batteries. Located in the payload module, the batteries run the propulsion system, airship services and provide power to the mission system for up to 14 hours(during winter). The airship is propelled and steered by means of a ’Contra-Rotating Coned Rotor’ mounted on a tailcone at the rear of the envelope, as a part of a compound propulsion system. The unit provides longitudinal thrust(to counter the prevailing stratospheric winds) and lateral force(for manoeuvering) to enable the airship to hold station within a 1 km cube. The airship will be equipped with a multi-channel Flight Control Sy

  • Turboalternators and Turbogenerators
DEF

An integral unit comprising a turbine and generator in which high pressure steam from a power station boiler is converted into mechanical energy in the turbines and thence into electrical energy by the generators.

OBS

Although in small sizes they may be gear-driven, and some may be dc [direct current] generators, the term turbogenerator generally means an ac [alternating current] generator driven directly from the shaft of a steam turbine.

OBS

turbo-generator set: term standardized by the IEC.

The pulsed plasma thruster(PPT) with solid propellant is used for low power propulsion systems; typically with an average power less than thirty watts. Capacitor stored electrical energy is used to create a pulsed arc discharge across the face of a block of propellant, teflon in most implementations to date. The combination of thermal flux, particle bombardment and surface reactions ablates and ionises a small amount of the solid material... The peak discharge current is high, in the region of tens of kA. The self-induced magnetic field acts on the ions moving in the electric field creating the discharge to create a Lorentz body force that accelerates the plasma. Teflon PPTs have enjoyed limited use in east-west station keeping and sun pointing applications. PPTs do not produce sufficient thrust to be considered as candidates to provide primary propulsion of future out of Earth orbit missions and were not considered for SMART-1.

The Life Science Glovebox will provide a sealed work area in which crew members can perform experimental procedures.... The enclosed volume of the Glovebox will be about one half cubic meter(approximately 16 cubic feet). As air circulates through the work space, activated charcoal filters will clean it continuously by adsorbing chemicals that may be present. In addition, a high efficiency air filter will remove particles and aerosols. Two HHRs [Habitat Holding Racks] provide the structural, mechanical, environmental, and communications support for the biospecimen habitats. The HHRs will provide life support resources and electrical power to the habitats and other scientific equipment, as well as data links to ISS [International Space Station] systems and the ground.

The Advanced Solar Gallium Arsenide Array(ASGA) will provide valuable information on the performance of gallium arsenide(GaAs) solar arrays and on the effects of the low Earth orbit environment on their components. These solar cells, already being used in a trial form to power the Soviet MIR space station, are expected to form the backbone of the next generation of compact, high power-to-weight ratio European solar energy generators.

The PVR [Photovoltaic Radiator] is a critical component of the space station's thermal control system. It will cool the photovoltaic power system electronic equipment and the batteries used for power storage. The PVR will also provide environmental cooling for the service module during early phases of the space station. Each PVR Orbital Replacement Unit(ORU) consists of 7 radiator panels, each about 6 feet by 12 feet in size. The radiator panels are designed to deploy on orbit from a stowed position about 2 feet high to an extended position about 50 feet in length. Each ORU weighs about 1, 600 pounds, with a total of 4 units in the final space station configuration.
