4 INTRODUCTION

This document is an introduction to some of the terms, facilities, equipment, test and measurement methods, and safety /environmental conditions of the ESA Propulsion Laboratory (EPL).

The EPL performs R&D testing activities and support to projects related to propulsion. The laboratory is ISO 9001 certified and has ISO 17025 Accreditation for direct and indirect measurement of thrust (the latter calculated from current and voltage measurement), mass flow, and electrical parameters (current and voltage) of the Propulsion System (thruster, cathode/neutralizer and power unit).

5 INFRASTRUCTURE

The EPL is located in the Ek building at ESA-ESTEC (Figure 1 below).

Figure 1: EPL building (up: from outside, down: from inside).

The EPL is divided into six rooms (see schematic Figure 2):

(10)

• A changing room (Ek032) by which the main laboratory is accessed.

• An assembly room (Ek032e) in which are stored critical devices and chemicals and which can be used to prepare test set-ups.

• A control room (Ek034) mostly used as a meeting room.

• An archive room (Ek036) in which is stored the EPL documentation and software.

• A storage room (Ek038) in which is stored hardware and consumables.

• The main laboratory (Ek045), with seven vacuum chambers and a flow rig bench.

Figure 2: EPL layout.

The total surface of the EPL is 12 x 30 m.

The main laboratory and the assembly room have an environment suitable to implement an ISO clean room, class 8¹ environment and conditions upon customer request. Those conditions can be applied if asked specifically by a customer.

A seismic block was installed in the EPL to prevent environmental noise perturbations. The seismic bloc is a 4.2 x 16.6 m concrete block of about 160 tons. It is mounted on 8 Airmount Firestone air springs for vibration isolation. Mechanical isolation from the laboratory is maintained by passive damping and has a 1 Hz cut-off frequency with a 20 dB per decade roll-off. The seismic block has a natural resonance of 0.8 Hz. For further information refer to RD01.

1 This number refers to ISO 14644-1 standards.

(11)

Figure 3: Picture of the seismic bloc in the EPL (RD01).

6 SAFETY AND ENVIRONMENTAL CONDITIONS 6.1 Safety conditions

The EPL, as part of the Mechanical Engineering Department (TEC-M), in the Directorate of Technical and Quality Management (D/TEC), completed in 2003 a Risk Assessment and Evaluation performed by a Certified Safety Institute.

This is subject to annual review and forms part of the developing Safety Management System.

In summary the main hazards are represented by:

• High voltages;

• Cryogenic liquids;

• Chemicals and alkaline metals.

Safety equipment, including personal protective equipment is available in the EPL and must be used by all staff, contractors and visitors during testing as necessary.

6.2 Environmental conditions

• The temperature in the EPL is maintained at 23° ± 5°.

• The humidity in the EPL is maintained at 50% ± 20%.

These are maintained by ESTEC Site Management Division (OPS) and monitored at all time by the EPL using a calibrated temperature and humidity probe (see section 8.5.3).

(12)

7 GENERAL EPL TESTING METHODS 7.1 Measurement procedures

The main goal of the EPL is to give support to projects in all propulsion related issues matters. This includes specific dedicated tests but also more general R&D testing activities.

When testing Propulsion Systems the three main parameters measured are:

• Thrust produced (T)

• Electrical power consumed (P)

• Propellant mass flow consumed (mf)

These three quantities are used to derive specific impulse (

g

0

m I T

f

sp

=

) and efficiency (

P m

T 2

f

=

2

η

). These five

parameters (thrust, power, mass flow, specific impulse and efficiency) are the critical parameters for a propulsion system.

The laboratory is ISO 17025 accredited for direct and indirect measurement of thrust and direct measurement of electrical power and mass flow. The corresponding measurement procedures can be found respectively in RD28, RD29 and RD30.

The EPL uses a wide variety of instruments to follow these procedures:

• Direct thrust measurements are performed with calibrated/validated commercial load cells or specifically designed balances, described in section 8.2.1.

• Direct mass flow measurements are performed with calibrated mass flow controllers, described in section 8.4.1.

• Direct electrical power measurements are performed using the readings of the used power supplies or digital multimeters, described in section 8.5.

• Indirect thrust (for electric thrusters) is inferred from the electrical measurements (currents and voltages) and beam properties of the thruster.

7.2 Validation and Measurement Traceability

The afore mentioned measurement procedures are validated by the ISO17025 accreditation. More general measurement procedures (such as temperature or pressure measurements) are adopted as-is without accreditation.

All critical measurement equipment used is calibrated by external calibration laboratories traceable to (inter) national standards.

(13)

(22)

8.1.8 Flow Rig

The Flow Rig is a test system, used by the EPL for the performance testing of components intended for use within a chemical propulsion system. The objective of the Flow Rig is to measure the pressure drop of water passing through a test component installed within the testing section of the Flow Rig and at a later date, water hammer effects.

The Flow Rig requires that pressures, temperatures and mass flow of the working fluid are measured in order to determine the performance of a test component.

The working fluid used for the Flow Rig is distilled water. The pressure drop characteristics of the water are measured throughout the system. This allows a good approximation to be made of the characteristics that would be expected when using other fluids by comparing the thermodynamic properties of both the water and the working fluid intended for use.

Test procedures have been written for pressure drop tests, and the first test campaign has been done. But an evaluation still needs to be done, to achieve full commissioning.

The user manual can be found in RD12.

A picture of the installation is given in Figure 11.

The EPL owns Leybold, Pfeiffer and Varian vacuum gauges.

Leybold vacuum gauges systems usually consist of two gauges, a read-out unit and cables. Each system is calibrated as a whole and it is important to use the gauges with their corresponding read-out system and cables. The instruments are calibrated once a year.

Table 3 lists all the vacuum systems available at the EPL.

8.7 Data Acquisition Systems

The EPL signal acquisition systems are built around National Instruments systems.

The EPL has seven DAQ which consist of at least a PXI-1052 chassis, an embedded controller and an optional ADC card (usually PXI-6220 or 6221). Two other DAQs are dedicated to CORONA, FEEP, Gigant and SPF feedback/diagnostic systems. These systems are listed below (Table 12).

These systems can be equipped with a wide variety of acquisition/conditioning cards listed in Table 12.

8.7.2 Software

Most of the DAQs run under Windows XP (except DAQ uNTB and SPF which run under Windows 7). LabVIEW is the main software used to acquire and produce signals. All versions up to LabVIEW 2012 are available. The licence serials for the LabVIEW full development system and toolkits are listed below:

Table 13: LabVIEW licenses.

LabVIEW full development system M64X15815

LabVIEW FPGA toolkit M63X89005

LabVIEW PID control toolkit H21H41404

LabVIEW Advanced signal processing toolkit H21H43052

LabVIEW Control design and simulation module M64X73999

Specific software is installed on each DAQ according to the needs of the tests.

All DAQs are protected by McAfee anti-virus 8.7, with an additional anti-spyware module. The virus information is updated daily at 4 AM (LAN).

8.7.3 Local Area Network

A Local Area Network (LAN) is available in the EPL.

The physical network connectivity is provided by means of the so-called "edge switches" on the walls of the EPL. These switches are managed by HP/EDS and configured as an isolated network with no routing towards the ESA corporate LAN (except for those marked "Estec LAN").

A small server has been deployed in the meeting room, connected both to the EPL network and the ESA corporate LAN. It provides the following services to the machines in the EPL:

• DHCP server, providing IP addresses and other network parameters

• DNS server, providing resolution of names to IP addresses

• File server, with a local copy of the anti-virus updates

• NTP server, for time reference

The server does not allow the machines in the EPL to go any further than the server itself.

Windows XP and later has the native capability to synchronise itself with a time source using the NTP protocol. This has been enabled on the computers so that they are synchronised against the ESTEC time source. Under ideal conditions, the precision that can be achieved is in the range of milliseconds.

8.8 Gas and chemicals

Several gases are used at the EPL:

• xenon

• nitrogen

• helium

• argon

Different chemicals are available in the laboratory:

• cesium

• microcote 296

• selenium

• potassium

• sodium

• zirconium

• Epo Tek H77

• rubidium

• tellurium

• IPA solvent cleaner

• Ultrasonic cleaner chemicals

• alcohols

• acetone

8.8.1 Feeding systems

The EPL owns different ready-to-use feeding systems. Most common connections are Swagelok compression and face seal VCR connections. Three systems are available:

(49)

• CORONA Xe gas feeding system (Figure 20)

• GALILEO gas feeding system (Figure 21)

• Resistojet feeding system (Figure 23).

8.8.2 Laminar flow benches

The EPL owns two laminar flow benches (INTERFLOW, class 100) and an Asecos chemical fumes extraction bench (Figure 24).
