22 Things to fix or add in the ELA format?

23 Joint AE-7 & AE-8 Meeting action
AE7 is asking for a list of requirements for a wire standard that they could fill in and give to the 8D committee o Provide a list of things that 8D can do and can’t  Where should the ‘high voltage’ limit be placed. o Will be unique to aerospace? o Could be part of AE-7, AE-8D group is not suited to do the research to develop the project. AE-7 should come to committee with a particular configuration for the committee. The goal is to get AE-7 (Power Systems Committee) to agree on what they need in the interconnect system to support the 270VDC, 230VAC, and the massive KVA rated Power Systems in the More Electric Aircraft. AE-8 is looking for the Power Systems folks to tell us what level of testing (rating) they will require for wiring system components and wire/cable. We also want to get standards written for commercial connectors, terminals, wire, or whatever they are using.

24 Review Slides from the Spring meeting
Legacy voltages 115 VAC LN, 200 VAC LL 26 VAC 28 VDC 270 VDC 230 VAC Variable frequency, LN, 398 VAC LL + 130 VDC Newest Voltage 540 VDC (+ 270 VDC) What’s Next 1000 – 5000 VAC, 1K -3k Hz 400 to 800 VDC Very Light Rotorcraft and Electrically Powered Sailplane Component voltage ratings

25 Voltage Testing required for EWIS components
Now 540 VDC (+ 270 VDC) Near-term 400 to 800 VDC – Very Light Rotorcraft and Electrically Powered Sailplane Other considerations IEC medium voltage limits of 1,000 VAC and 1,500 VDC will be exceeded when propulsion is considered for large transport and passenger aircraft. Electrical installation above 600VAC limits needs new standards Should consider transients testing up to two or three times the rated voltages need to be anticipated.

29 System Design Effects Higher Frequency Power Generating Systems
AC Inductance impedance increase the voltage drop by a 1.8X from 400Hz to 1200Hz. Large voltage drops on power feeders increase the internal heat load in the generator. Dielectric heating increase in the power feeder. Power Feeder design – Increase Wire Temperature Rating 800 VDC, 1.2MW, 100ft length, Wire Rating 260C = 2 - AWG 4/O 800 VDC, 1.2MW, 100ft length, Wire Rating 360C = 2- AWG 3/O 26% weight reduction, 43% increase in voltage drop 3-Phase 800 VAC, 800Hz 1.2MW, 100ft length, Wire Rating 260C - AWG 4/O 50% weight reduction, 4X increase in voltage drop 3-Phase 800 VAC, 800Hz, 1.2MW, 100ft length, Wire Rating 360C - AWG 3/O 60% weight reduction, 4.3X increase in voltage drop Examine increasing wire temperature to enable reducing system weight

30 At What Voltage Should We Be Concerned About Partial Discharge?
The existing fleet of more-electric aircraft are operating at voltages nominally set to 540V DC (+/-270V DC) and 230V AC RMS phase to earth (325V AC RMS phase to phase / 563V AC peak phase to phase). Should we be concerned about electrical discharge at these voltages / should we only consider partial discharge (corona) at voltages above 900V? Yes – we can get partial discharge or breakdown in any system with a voltage approximately higher than Paschen’s minimum, 327V The exact voltage at which partial discharge takes place will be defined by: The geometry and materials used in the insulation system The environmental conditions (temperature, pressure and various others) Any partial discharge that has previously taken place in that system

31 At What Voltage Should We Be Concerned About Partial Discharge?
We should note the need to consider voltages either side of nominal. They can go up for a range of reasons. However, we could potentially accommodate limited amounts of partial discharge as long as this is extinguished when the voltage returns to the nominal value (image from PhD of Benjamin Cella – Laplace) Some objects can fail extremely quickly if PD inception takes place (an IGBT module for example), others will likely have a long time to failure (PTFE based cabling for example).

43 New Business Hybrid-electric propulsion systems
Minimum Performance Standards for DC Propulsion Motor and Associated Voltage Regulators

44 Hybrid-electric propulsion systems

45 Aurora Overview Mission
eVTOL aircraft will provide on-demand transportation to minimize long commutes due to heavy traffic and urbanization in populated areas. The infrastructure plan includes urban “vertiports” for passenger boarding and vehicle servicing. eVTOL aircraft will operate a “hub-to-hub” service between designated vertiports. The first test bed flights are scheduled to begin in 2020 in Dallas, Texas, USA and Dubai, The United Arab Emirates.

46 Operational Overview The eVTOL aircraft includes eight lift rotors for vertical takeoff and cruise propeller and wing to transition to high-speed forward cruise. At destination hub, the aircraft transitions back to rotor-borne flight for vertical landing. Fully electric operation decreases or eliminates emissions and noise pollution for a quieter flight. While initially operated with a safety pilot, the eVTOL aircraft is designed for fully autonomous operations. The flight capability for eVTOL aircraft is three times more efficient than a multi-copter aircraft.

47 Aurora Flight Sciences XV-24A “LightningStrike
At 300 pounds, Honeywell’s megawatt generator is five times smaller in size and weight compared to other generators that produce similar power, said Tom Konicki, Honeywell Aerospace director of business development. Rolls-Royce is bringing to bear capabilities for hybrid electric power generation and distributed control systems, plus experience as an engine supplier on various VTOL platforms. Boeing has announced that it's buying Aurora Flight Sciences

48 Minimum Performance Standards for DC Propulsion Motor and Associated Voltage Regulators
A distributed electric propulsion system for a VTOL aircraft can exploit aerodynamic benefits that increase the lift to drag ratio by 4- to 5-times that of conventional helicopters ( This yields a fourfold increase in range while maintaining the VTOL and hover capabilities of a conventional helicopter. (LaunchPoint Technologies) There are many advantages for using electric propulsion on aircraft: power to weight (P/W) ratios exceeding 5HP/lb, direct drive propulsion, compact form factor, high efficiency over the majority of motor speed range, ability to overpower motors over 2x the continuous power ratings for short bursts, and the most significant, electric motors are effectively scale-free meaning the power to weight ratios, efficiencies, etc. are the same independent of motor scale. Elon Musk -- who has designed his own electric plane, of course -- said the necessary battery density threshold is about 400 Wh/kg, compared to around Wh/kg available in current Tesla models.

49 ASTM F Standard Practice for Design and Manufacture of Electric Propulsion Units for Light Sport Aircraft Significance and Use 3.1 This specification provides designers and manufacturers of electric propulsion for light sport aircraft design references and criteria to use in designing and manufacturing EPUs. 3.2 Declaration of compliance is based on testing and documentation during the design, ground testing and flight testing of the EPU by the manufacturer or under the manufacturers’ guidance. 3.3 Manufacturers of the EPUs are encouraged to review and incorporate appropriate standards and lessons learned from ground based systems as documented in SAE J2344 and EASA CRI F-58 (see Appendix X2). 3.4 Electric aircraft may contain potentially hazardous level of electrical voltage or current. It is important to protect persons from exposure to this hazard. Under normal operating conditions, adequate electrical isolation is achieved through physical separation means such as the use of insulated wire, enclosures, or other barriers to direct contact. There are conditions or events that can occur outside normal operation that can cause this protection to be degraded. Some means should be provided to detect degraded isolation or ground fault. In addition, processes or hardware, or both, should be provided to allow for controlled access to the high voltage system for maintenance or repair. A number of alternative means may be used to achieve these electrical safety goals including automatic hazardous voltage disconnects, manual disconnects, interlock systems, special tools and grounding. The intention of all these means is either to prevent inadvertent contact with hazardous voltages or to prevent damage or injury from the uncontrolled release of electric energy. Lightning strikes are not addressed in this Standard Practice because LSA aircraft are limited to VMC flight only.

52 New Business AIR on EPS Design Myths and Constraints

53 EPS Design Myths and Constraints
1.         “One size fits all”; a single architecture or design fits all aircraft applications 2.         Any commercial off the shelf (COTS) components can be used in military applications 3.         If a design meets all ‘spec’ requirements during test, it will work as expected in the ‘field’ 4.         An optimized design always results in weight & volume savings 5.         Integration of optimized components always results in an optimized integrated systems design 6.         The EPS does not have to interface or interact with other systems to perform its functions 7.         Building and testing hardware is cheaper than using model based design during development 8.         Use of automated design tools always saves time and money 9.         Once the prototype design or schematics are complete, the hard work is over Please provide your inputs; the goal is to publish an AIR document.

54 EPS Design Myths and Constraints
10.        Prototype designs are always good for final production         Components can be placed anywhere in an architecture and the design will be ‘effective’         Power management and distribution functions are not critical for safe designs         Grouping or locating components together is a good use of space and good design practice         Sizes of conductors, feeders, and connectors can be one size fits all         Sizing for average or continuous electrical loads is sufficient for all operating modes         Requirements never grow; the first design will never change         Steady-state, point designs (and testing) are sufficient to meet all requirements

58 Document review and comments
AIR Fundamentals in selecting Wire Sizes in Aerospace Applications Document review and comments The scope of this report is to capture the fundamental principles of selecting a wire size for an aerospace application using the method prescribed in SAE AS50881 standard. Also, provided in this report are additional calculations to ensure the wire selection will adequately perform in a particular design function including meeting environment constraints. Some of the calculations in this report have been simplified to demonstrate the process for validating the wire size selections for a particular design application. More precise calculations should be investigated and evaluated to ensure proper assessment of each individual calculation in this report. Go to Ballot?

59 SAE AE2 Lightning Committee working group Coordination
AIR XXXX, Comparisons of EMI Requirements and Test Procedures Characterized in Commercial Aerospace Standards and MIL-STD-461G Current proliferation of commercial aircraft modified to perform military missions (Commercial Derivatives) has established the need to assess the suitability, from an airworthiness and performance perspectives, of using equipment qualified to commercial electromagnetic interference (EMI) standards in military applications This Aerospace Information Report (AIR) will document the results of detailed comparisons of individual requirements and test methods in MIL-STD-461G with similar aerospace equipment commercial standards. The information that will be part of this report will facilitate cognizant EMI personnel to determine if equipment qualified to commercial standards is appropriate for use in military applications/missions or if it requires additional EMI certification testing Likewise, this AIR will facilitate the assessment of equipment certified to the requirements and test methods of MIL-STD-461G for their use in commercial aviation
