The AIAA and Challenger Center have launched the Trailblazing STEM Educator Award. This annual award will celebrate K-12 teachers going above and beyond to inspire the next generation of explorers and innovators.

The award will recognize teachers who connect classroom lessons to the country’s current and future plans for exploration and innovation, introduce students to STEM careers, and spark students’ imagination about space exploration. Following a year of incredible challenges for educators, this year’s award also will celebrate educators who continued to excite their students about STEM throughout the difficult circumstances caused by the COVID-19 pandemic. Nominations are being accepted at aiaa.org/TrailblazingSTEMEducatorAward and may be submitted through 30 January 2022.

Five finalists will be selected from the nominations. Each of the finalists and their respective schools will be awarded $5,000; each finalist also will receive free access to Challenger Center’s STEM programs, a trip to Washington, DC, to be honored at the AIAA Aerospace Spotlight Awards Gala, and a special presentation ceremony at their school.

“We are excited about our collaboration with Challenger Center supporting those who are invaluable to our communities – educators. We share a commitment to strengthening the aerospace profession by inspiring the future workforce,” said Dan Dumbacher, AIAA executive director. “We need a diverse and robust STEM next generation who use what they learn today to innovate and invent tomorrow. We can’t wait to recognize these passionate and inspirational trailblazers who spark students’ interest in STEM subjects, especially the science and engineering behind aerospace.”

Even as the U.S. aerospace and defense industry leads the world in innovation, it faces challenges with the workforce: a skills gap of STEM-literate students entering the industry, a need for greater participation by women and ethnic minorities, and a growing knowledge gap from early retirements. Based on the “2021 AIAA State of the Industry Report,” nearly 50% of respondents believe an increased focus on diversity, equity, and inclusion by aerospace industry employers will help increase the pipeline of skilled, competent aerospace professionals.

By Kevin Burns, AIAA History Committee Chair

This year the AIAA History Committee started its preparations for the 2031 AIAA Centennial. Our goal is to have papers presented at AIAA SciTech Forums over the next decade on the history of each committee, section, branch, and organization within AIAA. We will kick off with a session on the History of AIAA at the 2022 AIAA SciTech Forum. Rocketeers and Gentlemen Engineers, written for AIAA’s 75th anniversary in 2006, chronicles the social history of the Institute. The papers and presentations in the coming years will allow a more technical understanding at the grassroots level of how the Institute came together and grew over the last century. The committee encourages our committees and sections to mentor students and young professionals in writing these papers, so that they can get published early in their careers and experience the publication and presentation of a paper. More information about the History Committee and advice for writing history papers for AIAA SciTech Forum can be found on its website at aiaahistorycommittee.com, or by contacting the committee chair at [email protected].

AIAA also has joined the Engineering and Technology History Wiki (ETHW) consortium in 2021 (www.ethw.org). The website has thousands of articles, firsthand accounts, oral histories, milestones, archival documents, and lesson plans pertaining to the history of technology. It fosters the creation of narratives that not only document the history of engineering practices but also explain when, how, and why these technologies developed as they did. Over the next year, the History Committee will be working to establish liaisons with other AIAA technical committees to develop content within the aerospace engineering category of the transportation history section of the ETHW. All AIAA members are encouraged to contribute content. Those interested in this project can contact the History Committee chair at [email protected]./

The Langley Alumni Association and NASA Langley Research Center partnered to develop the Hall of Honor to provide a way for distinguished Langley Research Center researchers and managers to be honored for their exemplary contributions and careers at NACA, NASA, and the nation at large in the pursuit of revolutionary scientific understanding and technological progress on the frontiers of aerospace sciences. The Hall of Honor also provides a focused opportunity for the local aerospace community to reflect on the contributions of these notable individuals who made enduring impacts on aerospace technologies.

We encourage you to consider nominating a deserving individual for the Hall of Honor Class of 2022. All nominees must satisfy the selection criteria found at https://larcalumni.org/nomination-form, and nominations must be received by 14 January 2022. If you have any questions, please email [email protected].

The 2021 Jay Hollingsworth Speas Airport Award was presented to the Jackson Hole Airport Board at the 2021 AAAE National Airport Conference (27–28 September, Savannah, GA).

By Michael Spencer, AIAA Sydney Section Committee, and Tjasa Boh-Whiteman, Co-Chair, AIAA Sydney Section

To keep their members informed about different areas of the aerospace industry, the AIAA Sydney Section recently invited Wing Commander Keirin Joyce, Royal Australian Air Force, as a guest speaker. He is a currently appointed as the Chief Engineer for Remote Piloted Aircraft Systems (RPAS): MQ-4C Triton and MQ-9B SkyGuardian.

On 21 September, he delivered a public lecture on his views of the military Uncrewed Aerial Systems (UAS) that are currently in service or being considered for acquisition out to the year 2040 in the Australian Defence Force. Due to government-mandated COVID-19 lockdown restrictions, this AIAA Sydney Section event was hosted online as a livestreamed presentation.

A graduate of the Australian Defence Force Academy (ADFA) with an Honours Bachelor of Aeronautical Engineering, WGCDR Joyce has spent the last 15 years supporting the Australian Defence Force (ADF) to better understand, utilize, and acquire UAS capabilities, including joining operational deployments to Iraq and Afghanistan. He is a Chartered Professional Engineer with master degrees in Aviation Management (Human Factors), Aerospace Engineering, and Military and Defence Studies, and a part-time Ph.D. research student at UNSW Canberra/ADFA. WGCDR Joyce was responsible for all Australian Army UAS activities, including Army Drone Racing and drone videography, before transitioning to the Royal Australian Air Force as the Remotely Piloted Aircraft Systems (RPAS) Sub-Program Manager, before being appointed the Chief Engineer, RPAS.

During his career as an Army engineer, he supported Army to adopt an incremental capability approach to incorporating drones across the Army organization of its warfighters. The Australian Defence Force (ADF) Drone Racing Team was established as a non-traditional sport that overlaps both work and personal interests with Army, Navy, and Air Force participation, enabling ADF and STEM to be promoted to soldiers, sailors, and aviators and youth interested in becoming the next generation military.

The most recent Defence Strategic Update steers the ADF to adopt remotely operated and autonomous air vehicles that provide increased lethality and survivability, improve battlespace situational awareness, and complement existing aircraft capabilities, including investigating the potential for teaming air vehicles. To aid this transformation and keep the momentum of change, Army has acquired a COTS Multi-Rotor UAS for issue to every Army unit, enabling everyone in Army to improve their drone literacy, supplement counter-UAS awareness, and familiarize soldiers with how UAS pose a new and fast-growing threat to small units, plus support the Army development of better UAS training.

Army has invested in a drone strategy to provide operational drones in capability increments of increasing mass, size and performance, corresponding to the size of the force element. Army drones range from pocket-sized nano-UAS (e.g., Black Hornet) for combat platoons; medium-sized hand-launched Small UAS (e.g., Wasp AE) for every combat team; up to a catapult-launched Tactical UAS (e.g., Shadow 200) to equip a deployable brigade without needing an established runway.

The Navy is also investing in an exciting drone program with two different types of drones: catapult-launched ScanEagle fixed-wing drone and Schiebel S-100 vertical lift helicopter drone. These drones provide the Navy with new experiences adapting technologies to conduct flights between the shore and a warship and flights at sea.

Air Force is doctrinally roled to acquire and operate the very large-sized drone capabilities for the ADF. ADF doctrine ensures no unnecessary duplication of combat capabilities within the Army, Navy, and Air Force. Each contributes combat elements to be integrated and work cooperatively within the same ADF deployed Joint Task Force (JTF) to deliver a military effect that meets an operational need jointly. Air Force is currently acquiring two remotely piloted aircraft systems: the MQ-4C Triton high-altitude long-endurance RPAS for conducting intelligence, surveillance, and reconnaissance (ISR) missions and the MQ-9B SkyGuardian medium-altitude long-endurance armed RPAS for ISR and strike missions. These large-sized RPAS UAS are roled for Air Force to provide ISR and strike support to a JTF.

The Triton project is the biggest RPAS project at the moment. Acquired under a cooperative program arrangement with the U.S. Navy, Triton is the most modern iteration of the Global Hawk design but when the two designs are compared side-by-side, they’re very different aircraft.

Another cool and exciting experimental ADF project is the Loyal Wingman – a $40 million investment in the Boeing Air Power Teaming System (BATS). This fighter-size aircraft has a similar performance range and speed to match a conventional crewed fighter aircraft, except that the BATS flight controls and mission are planned to be autonomously controlled by artificial intelligence (AI). WGCDR Joyce is excited that about 80% of the Loyal Wingman’s development effort has occurred with Australian content. About 70% of the actual aircraft is designed, built, and assembled in Australia. This effort represents the ADF’s first step toward developing a concept for air combat teaming between human and AI-controlled aircraft systems.

The AIAA Sydney Section is very grateful for the opportunity to have Wing Commander Joyce share his experiences and insights into the UAS/RPAS capabilities in the Australian military and their impacts on the broader interests and applications for drones and aerospace engineering. A video recording of this AIAA Sydney Section event is available for viewing on the Facebook and YouTube channels for the AIAA Sydney Section at https://youtu.be/iO0hB1KrdwA.
