The monopropellant propulsion systems may typically use one of the following main architectural concepts: - Single branch propulsion, versus dual-branch (redundant) propulsion. - Low-thrust thrusters (5N or 1N), or high-thrust thrusters (25N). Architectures shown: - Four thrusters, single-branch propulsion system architecture - Four thrusters, dual-branch (redundant) propulsion system architecture - Dual-Tank & dual branch propulsion (redundant) architecture with eight thrusters - Dual-branch (redundant) propulsion architecture with thrusters and PTs at branch-level PART B - Satellite Propulsion Systems (Page 15) Hydrazine Propulsion System - Architecture - The Propellant is loaded into the tank through a fill and drain valve (FDV). - The pressurant gas is filled into the opposite side of the tank through a fill and vent valve (FVV). - A flexible EPDM diaphragm separates between the propellant and the pressurant Inside the Tank. - The tank maintains a gas pressure ratio of 4:1 (BOL/EOL). - A pressure transducer installed on the propellant line enables monitoring the propellant pressure which indicates the residual propellant quantity during the mission. - The latching valves (LV), provide an additional mechanical barrier for the hydrazine to meet the launch safety requirements and enables the option to disconnect the relative branch in case one of the thrusters fails throughout the mission. - Once the latch valve is switched to OPEN, the pressurized propellant may be expelled towards the thrusters. Integral dual-seat dual-coil normally-closed flow control valves (FCV) control the propellant flow into the thrusters; thus the design satisfies the common three-barriers requirement. - The pressure transducer is used throughout the service life of the satellite to estimate the residual hydrazine level; the pressure level is used by the control system as a parameter for estimating the available thrust. - The system architecture is selected according to mission and reliability considerations. - The use of redundant twin-branches propulsion significantly increases the system reliability. - The system can include two types of thrusters, High Thrust (HT) or Low Thrust (LT), according to mission requirements. The thrust of the high thrust level thrusters may be chosen as 25N or 5N. The thrust level of the low thrust thruster may be chosen as 5N or 1N. - Differences between the chosen system architectures are derived from the mission and satellite requirements for reliability, lifetime, weight and number of thrusters. - All Rafael propulsion systems and components flown have demonstrated 100% mission success, with no system or component failures or loss of redundancy.

PART B - Satellite Propulsion Systems (Pages 17-18) Design Considerations and ICD: During the design phase of the Propulsion System (PS) all the relevant considerations related to the satellite are taken into account, such as: - Mechanical interfaces and mass budget - Electrical interfaces, power consumption and control commands - Thermal control, heat dissipation and radiation budget. Mechanical Interfaces: The propulsion system components (e.g. tank, thrusters, LV, FDV/FVV, Manifolds, etc.) are installed on the satellite structure. Two basic concepts of a PS components installation are available: - On a dedicated base plate (Plug-In Propulsion System) - Dispersed at various locations in the satellite. In the case of using a dedicated base plate concept, the base plate itself may be supplied by Rafael, or by the Customer. The PS, together with the base plate, is installed as a plug-in module to the satellite. The tank can be installed, held at the equator or poles, on the base plate or struts, subject to project requirements. Electric Interfaces: Rafael provides full electric interface for the Propulsion Systems. A typical PS electrical design includes the electrical harnesses which perform the link of command lines between the satellite and the active elements of the PS. Electric wires, in accordance with space standards, are routed to on-board electrical devices. All splices, shrinks, crimps, lacing and soldering comply with ECSS-Q-70-08A. Typical PS uses regulated (28±4 VDC typical) and unregulated voltage (25 to 45 VDC). The regulated voltage is supplied to the PS valves (FCV's, LV). The unregulated voltage may be used for the subsystem heaters. Rafael performs overall electrical tests and provides a ready-to-connect plug-in module to the Satellite. Thermal Control: Rafael is capable of delivering an all-around full thermal control solution as an integral part of the propulsion system. Rafael's expertise is available for tanks as well as for thruster FCVs and for pipes; the capabilities include thermal analysis, thermal control design with redundancy options, specification of heating requirements, determining locations for heating elements (thermostats, thermistors) and use of thermocouples for heat measurement of thruster TCAs. The heating controllers are governed by the satellite's main control unit. PART B - Satellite Propulsion Systems (Pages 19-20) Electric Propulsion System: Rafael designs, develops and manufactures Electric Propulsion Systems (EPS). The Venµs satellite (a CNES & ISA cooperation) was launched in 2017. Rafael supplied its EPS, which is successfully operating since and gaining heritage. The Rafael EPS for the Venµs satellite is designed to support and operate two IHET-300 Hall-Effect thrusters (HET), designed for low-power operation. Venµs EPS's main components are the 2 Hall-Effect Thrusters, Propellant Management Assembly (PMA), Digital Xenon Flow Controller (DXFC), Power Processing Unit (PPU), and 2 Filter Units (FU). The PMA is composed of a tank, storing up to 16kg of high pressurized Xenon, and of a set of valves, pressure reducers and manifolds to transport the gas. The PPU comprises the power supplies and the sequencer command logic to operate the thrusters. The FU's function is to filter and to mitigate the thruster oscillations. For missions requiring thrust flexibility, a variable thrust mechanism is incorporated. The Rafael EPS incorporates a DXFC that serves as the "throttling" device for the xenon flow rate through the HET-300 anode. R-800 EPS Electric Propulsion System: The R-800 EPS is an electric propulsion system operating in the 450-900 W power range. The system consists of a Hall thruster unit, Power Processing Unit (PPU) and Propellant Management Assembly (PMA). The propulsion system is based on Rafael's R-800 Hall Effect Thruster. The R-800 EPS is Rafael's second-generation EPS system following the Space-Qualified R-400 EPS (Venµs EPS) success. The R-800 thruster has recently completed its qualification. Lessons learned during its initial development led to many improvements that were implemented with the purpose of producing a lighter-weight, electrically and mechanically robust thruster capable of operating in the expected environment of space. The thruster, including its corresponding low current heaterless hollow cathode completed the qualification process during which it underwent a full performance test, shock and vibration test and was operated in an endurance (lifetime) experiment. In addition, the thruster's operational envelope was tested at power levels from 450 W and up to 1350 W, to verify operation robustness. The thruster was operated both on Xenon and Krypton propellants. Typical mission applications of the R-800 EPS include: - Orbit keeping and drag compensation for LEO, down to altitudes below 350 km. - Enabling formation-flying missions of small-satellites. - Accurate and precise final orbit insertion after separation from launcher. - Mission orbit change and disposal deorbit at end of life. PART C - Propellant Tanks (Pages 21-23) Propellant Tanks Summary Table: - PEPT-200: Tank Nominal Volume 3.55 [Liter], Qualified Propellant Capacity 3.3 [Liter] - PEPT-230: Tank Nominal Volume 6 [Liter], Qualified Propellant Capacity 4.5 [Liter] - PEPT-260: Tank Nominal Volume 9.3 [Liter], Qualified Propellant Capacity 7 [Liter] - PEPT-330: Tank Nominal Volume 17.5 [Liter], Qualified Propellant Capacity 15.4 [Liter] - PEPT-420N: Tank Nominal Volume 37.5 [Liter], Qualified Propellant Capacity 30 [Liter] - PEPT-590: Tank Nominal Volume 102.5 [Liter], Qualified Propellant Capacity 75 [Liter] - PEPT-590GB: Tank Nominal Volume 204 [Liter], Qualified Propellant Capacity 154 [Liter] Note: The tanks can be partly filled in all configurations up to the full propellant capacity due to the use of a diaphragm as propellant management device. Positive Expulsion Propellant Tank – General Description: Rafael's Positive Expulsion Propellant Tank (PEPT) is made of 2 6Al-4V titanium alloy thin-walled hemispheres (optionally with a cylindrical mid-section extension). Positive fuel expulsion is provided by an EPDM-based rubber diaphragm retained between welded parts inside the tanks. Pressurant and propellant ports are weldable, 1/4" titanium tubes. The Propellant Tank is made of the following segments: - Lower hemisphere - Upper hemisphere - Cylindrical extension section – optional - EPDM-based, silica-free rubber diaphragm Integration to a complete tank is accomplished through peripheral Electron Beam Welding (EBW). The hemispheres are hot-formed and machined to final dimensions. The design of the hemispheres enables the incorporation of integral pressurant and propellant ports. The diaphragm has a 15 years life expectancy with hydrazine inside and has been qualified for various missions and satellite busses, such as Globalstar2, Myriade, Proteus, Galileo, Exomars, Neosat, OFEQ and others. The diaphragm has been qualified for use with ADN-based "green" propellant. Diaphragm Propellant Management Device: The diaphragm allows active and efficient propellant management throughout the satellite's lifetime. It allows multiple cycles of filling and emptying, simulation tests, as well as system integration and other tests. In contrast to a surface tension-based propellant management device, a tank equipped with a diaphragm does not limit the degree of filling in any of the operational stages. The tank may be partially filled to any degree, including prior to horizontal transportation on the launch pad, and the necessary gas-free propellant feed is assured for any subsequent demand. Another advantage is superior control over liquid sloshing. This superior propellant management by diaphragm prevents undue sloshing loads which might adversely affect satellite stability during launch and maneuvers in space, as well as propellant feed which is made free of any limitations caused by satellite orientation, movement, or acceleration. Positive expulsion by the diaphragm prevents excessive center-of-gravity shift as caused by propellant movements in surface tension or bladder type tanks during satellite maneuvers, thus preventing excessive attitude-control system requirements.

The thruster was designed and qualified for the OFEQ program. The Rafael 1N thruster was chosen for the following programs: Globalstar-2 (by TAS-F), O3B constellation (by TAS-F), NEOSAT Space bus (by TAS-UK), Cosmo SG (by TAS-I), Prisma (OHB-I) and for ESA programs: Galileo IOV (by EADS-ST), Sentinel-1 A, B, C & D (by TAS-I), Koreasat (by TAS-I) and Sabia-Mar (by CONAE). The 1N thruster is governed by a solenoid-operated, dual-coil, dual-seat normally-closed Flow Control Valve (FCV). Normally-closed position is maintained by springs for both seats. The FCV is equipped with an integral, 15 micron absolute filter, installed at the valve inlet. The normally-closed FCV is operated by its solenoid, opened when energized and shut-off by electric switch-off. The valve is an all-welded construction. The FCV consists of inlet port (filter included), valve body, coils (2), springs (2), seats (2), plungers (2) and a mounting flange. The all-welded FCV and the Thrust Chamber Assembly (TCA) are assembled together through a perforated, Hayness-alloy tubular element, which serves as a thermal barrier. The thermal barrier controls heat conduction from the TCA to the FCV throughout thruster operation and the heat soak-back period. A metallic seal provides leak tightness between FCV and TCA. The TCA incorporates a bell-shaped nozzle with expansion ratio ε=130 welded to the decomposition chamber. Rafael's thrusters are free of ITAR restrictions. Equipped with electric catalyst bed heater (CBH) with two resistance coils. Recommended pre-heating temp is 180°C (~20 min from +25°C).
