This is a dynamically shifting time for power and energy systems that mobilize space and aeronautical vehicles. New paradigms in the propulsion field and operational efficiency are upon us, including in the areas of electric aircraft, hybrid rockets, automation, robotics, and hypersonics. The tipping point for these technologies to become a reality and be fully implemented is near.

In addition to the historically strong propulsion and energy topics, the 2019 forum will also offer: (Includes topics from the AIAA Space Technical Community in 2019)

  • Enhanced space content, from cislunar space to small satellites to space architecture
  • Executive-level focus on space propulsion, energy science, air-breathing propulsion, electric propulsion, and more

The next generation of aircraft will face more challenging demands in both electrical and thermal loads. A critical element to the success of new propulsion technologies that enable reductions in fuel use is the integration of component thermal management technologies and power systems within engine controls and a viable vehicle package. Vehicle operation requires vehicle thermal management systems capable of balancing the needs of multiple vehicle sub-systems that may require heat for operation, require cooling to reject heat, or require operation within specified temperature ranges.

Developing advanced controls and health management (HM) technologies that will help meet these challenges through the concept of Advanced Intelligent Propulsion Systems. The key enabling technologies for an Intelligent Propulsion System are  active control, advanced diagnostics and prognostics integrated with intelligent engine control to enhance operational reliability and component life, and distributed control with smart sensors and actuators in an adaptive fault tolerant architecture. The objective of advanced intelligent engine controls is to develop and validate advanced control system and health prognostics and diagnostics technologies that are critical to enhancing the safety, reliability and operability of aerospace propulsion systems.

This topic is about the applications of solar power as the primary power generation source for Electrical Power Systems on space satellite designs. Papers related to solar array designs that have flown or baselined to be flown in earth orbit (LEO, MEO or GEO) and on interplanetary missions will be relevant. Additional topics include emerging photovoltaic technologies such as higher efficiency photovoltaic applications, higher power (>20 kW) flexible solar array designs, solar concentrators, and usage in conjunction with Electric Propulsion. 

  • Building New Technologies through NASA's Solar Electric Power (SEP) Program
  • Large Solar Array Design (>25kW) and Flight Performance
  • Solar Array Concentrator Mission Design
  • Solar Array Design for High Current and High Voltage EPS

AIAA/IEEE Electric Aircraft Technologies Symposium (22-24 August)

Please direct questions to:  
Phil Ansell, University of Illinois at Urbana-Champaign 

The aerospace industry has set ambitious goals for the next three generations of commercial transport aircraft to accommodate rapid growth in emerging markets and ensure sustainability of air travel. One approach being explored to meet these targets is non-traditional aircraft propulsion using electric, turboelectric or hybrid-electric powertrains. Recent events by the IEEE and AIAA have identified the need to bring together electrical engineers and aerospace experts as the industry looks to more electric propulsion technologies for future aircraft. These events include the 2018 EATS, which featured four keynote addresses, an active panel session, 57 technical presentations, and over 170 attendees.  

This two and a half-day symposium will focus on electric aircraft technology across three general areas: (1) electric-power enabled aircraft configurations and system requirements, (2) enabling technologies for electric aircraft propulsion, and (3) electric aircraft system integration and controls. Abstracts with a minimum length of 1200 words are encouraged. Successful submissions must also include sufficient detail to demonstrate the purpose of the paper, the technical foundation for the topics to be discussed, any preliminary results to date, and the expected results of the final paper, including key figures, equations, tables, and references, as appropriate. Papers are solicited in all relevant areas including, but not limited to, those listed below.  For more detailed information about each topic please see  Additional Details.  

  • Topic Area 1: Aircraft Configurations & Systems Requirements  
  • Topic Area 2: Enabling Technologies and Components  
  • Topic Area 3: System Integration and Controls 

All are welcome at the Electric Aircraft Technology Symposium, however, please note this event will be co-located with the AIAA Propulsion and Energy Forum and will require a separate registration fee for participants and attendees.

The following Student Paper Competitions are being held in conjunction with the forum:

Ann Delleur, NASA Glenn Research Center

Undergraduate and graduate students (Master’s level and PhD level) are invited to submit papers for consideration in the Aerospace Power Section Student Paper Competition. Papers should report on original work conducted by the student in collaboration with faculty advisor(s), mentors, and/or industry/government mentors. The student submitting a paper for consideration must be the primary author.

Entries to the Aerospace Power Section Student Paper Competition must undergo the regular abstract review process, and if accepted, will be included in the regular technical sessions with other papers in their topic area and be archived as AIAA conference papers. When submitting an abstract for the Aerospace Power Student Paper Competition, authors must choose the “Student Paper Competition” Presentation Type at step 2 of abstract submission, and then select one of the following topics:

  • Aerospace Power Systems 
  • Energy Conversion Technology 
  • Space Solar Power 
  • Space Nuclear Power Systems

The manuscript submission deadline for the Aerospace Power Section Student Paper Competition is the same as the submission deadline for the 2019 AIAA Propulsion & Energy Forum.  All entries to the Student Paper Competition must be received by this date to be considered in the competition. The submissions will be judged based on the paper ONLY. Criteria for judging the paper include 1) originality of the work; 2) scientific integrity, 3) relevance to the field of Aerospace Power; 4) significance technical quality and completeness of the work; and 5) written clarity and style consistent with AIAA paper guidelines.
