CONT

The Zarya control module, also known by the technical term Functional Cargo Block and the Russian acronym FGB, was the first component launched for the International Space Station and provides the station's initial propulsion and power.... The U. S.-funded and Russian-built Zarya, which means Sunrise when translated to English, is a U. S. component of the station although it was built and launched by Russia.... The Zarya module is 41. 2 feet long and 13. 5 feet wide at its widest point. It has an operational lifetime of at least 15 years. Its solar arrays and six nickel-cadmium batteries can provide an average of 3 kilowatts of electrical power. Using the Russian Kurs system, the Zarya will perform an automated and remotely piloted rendezvous and docking with the Service Module in orbit. Its docking power will accommodate Russian Soyuz piloted spacecraft and unpiloted Progress resupply spacecraft. Each of the two solar arrays is 35 feet long and 11 feet wide. The module's 16 fuel tanks combined can hold more than 6 tons of propellant. The attitude control system for the module includes 24 large steering jets and 12 small steering jets. Two large engines are available for reboosting the spacecraft and making major orbital changes.

CONT

The Zarya module now provides orientation control, communications and electrical power attached to the passive Unity module while the station awaits launch of the third component, a Russian-provided crew living quarters and early station core known as the Service Module ... The Service Module will enhance or replace many functions of the Zarya. Later in the station’s assembly sequence, the Zarya module will be used primarily for its storage capacity and external fuel tanks.

Mothballing is the process of stabilizing a facility so that no damage occurs to the facility should it make sense at a later time to incur the capital expenditures associated with continuing to operate, extending the life, or repowering the facility. Typically, a decision to mothball a facility might be made as a hedge against, or in anticipation of, changes in market conditions; i. e., increases in relative fuel prices, or an increase in the value of installed capacity.... Typical activities involved in mothballing a facility might include the following types of activities intended to preserve existing equipment :-’Racking Out’ or removal and storage of motor control center circuit breakers or 'switchgear’(this would also be done for a facility that has been retired and is scheduled for dismantling)-Placing a heat source or desiccants in the furnace to maintain a temperature above the dew point(at which condensation collects and corrodes the boiler structures.)-The application of grease or other coatings to reduce corrosion of components such as pumps and motors.-The installation of an air desiccant system to blow dry air through the steam turbine, condenser, boiler tubes and pipes.

Normal fuelling is accomplished through dual fuel nozzle adapters located on the right wing leading edge spar at the fuelling stations. All fuelling operations, except fuel pump control, are accomplished at the fuelling station. Opening the station access door applies DC power to the fuelling system and removes the N3 inhibit to the centre tank fuel pumps. Fuel flows through the dual nozzles to pressurise a fuelling manifold. Fuelling valves control the flow of fuel from the fuelling manifold into each of the three switches on the fuelling panel. A fuel quantity may be preselected for each tank. The fuelling valves close automatically when the preselected quantity is reached or when the tank is full, whichever occurs first. A tank overfill system is provided to prevent fuel spillage. If any fuel is sensed in the surge tanks during fuelling, a signal is sent to close all fuelling valves. The aircraft is filled automatically by hydrant or tank truck pressure. All tanks may be fuelled at the same time. The main tanks may also be fuelled manually through over wing fill ports.

A rocket propellant consisting of a single substance, especially a liquid, capable of creating rocket thrust without the addition of a second substance.

CONT

A monopropellant is a chemical propulsion fuel which does not require a separate oxidizer. A rocket engine which is based on a monopropellant requires only one fuel line instead of a fuel and an oxidizer line. The "mono" in monopropellant means singular-a fuel that can function alone. A chemical propulsion system that combines like hydrogen and oxygen would be a bipropellant. A monopropellant burns by itself because the oxidizer is bound into the molecule itself. This makes the rocket engine lighter, less expensive, and more reliable. Monopropellant designs are typically used in control thrusters but not in actual propulsion units.

CONT

The most commonly used monopropellant is hydrazine (N2H4), a chemical which is characterized as "strongly reducing". The most common catalyst is granular alumina coated with iridium (aka. Shell-405). There is no igniter with hydrazine. Shell 405 is a spontaneous catalyst, that is, hydrazine decomposes on contact with the catalyst. The reaction is highly exothermic and produces an 1800°F (1000°C) gas that is a mixture of nitrogen, hydrogen and ammonia. Another monopropellant is hydrogen peroxide, which, when purified to 90% or higher concentration, is self-decomposing at high temperatures or when a catalyst is present.

Fuel in the D4D is pressurised to an extremely high 135mpa within the "common rail" that feeds all four cylinders (older diesel engines have a separate pipe leading from the pump to each cylinder). The high pressure injection creates better fuel atomisation for complete burning and increased power output. And because there is less fuel wasted through inefficient combustion, the D4D delivers better fuel economy too.

OBS

A common rail engine is designed to supply constant fuel pressure to electronically controlled injectors through a shared fuel reservoir. This means that the fuel supply is not dependent on the engine revs. A common rail system is built around four basic components : a high pressure pump with pressure regulator and inlet metering valve, a rail which contains a pressurised reserve of fuel, injectors which inject precise amounts of fuel into the combustion chamber as required and a Diesel Control Unit-the ’brain’ of the system, which precisely controls injector flow and timing as well as rail pressure while continuously monitoring the operating conditions of the engine.

... The Progress supply vehicle to the ISS [International Space Station] is an automated version of the Soyuz, and was developed to carry propellant and cargo to the Salyut and Mir space station. It will serve the same purpose for the ISS. Although the ISS has its own propulsion system, generally it is the Progress vehicle that will perform periodic reboost maneuvers to maintain the ISS orbital altitude. The Progress is approximately the same size as the Soyuz, but it has a slightly higher mass at launch of approximately 7150 kg. The Progress spacecraft docks automatically to the ISS, and the TORU [Teleoperated Control System-Manual Docking System on Zarya] system acts as a backup remote control docking system. Progress is composed of three modules : the Cargo Module, the Refueling Module, and the Instrument/Propulsion Module. A modified version of the Progress M, called the Progress M1, is planned for operation with the ISS. This version will have more propellant tanks for refueling, as the entire Refueling Module is devoted to fuel. Water will be carried in the Cargo Module. The Progress payload includes cargo in the pressurized Cargo Module and propellant in the Refueling Module. Excess propellant that is usually in the propulsion system tanks in the Instrumentation/Propulsion Module can also be used by the ISS.

Environment Control and Life Support System(ECLSS) : The orbiter's Environmental Control and Life-Support System purifies the cabin air, adds fresh oxygen, keeps the pressure at sea level, heats and cools the air, and provides drinking and wash water. The system also includes lavatory facilities. The cabin is pressurized to sea level(14. 7 psi) with 21 percent oxygen and 79 percent nitrogen, comparable to Earth's atmosphere. The air is circulated through lithium hydroxide/charcoal canisters which remove carbon dioxide. The canisters are changed on a regular basis. Excess heat from the cabin and flight-deck electronics is collected by a circulating coolant water system and transferred to radiator panels on the payload bay doors where it is dissipated. The fuel cells produce about seven pounds of water each hour. It is stored in tanks, and excess water is dumped overboard. The lavatory unit collects and processes body waste, and also collects wash water from the personal hygiene station. The lavatory unit, located in the middeck area, operates much like those on commercial airlines but is designed for a weightless space environment.
