The Dale Reed Subscale Flight Research Laboratory Legacy

The Dale Reed Subscale Flight Research Laboratory is a testament to the pioneering spirit of its namesake, Robert Dale Reed. Reed, an aerospace engineer whose career spanned more than three decades at NASA, revolutionized experimental aircraft design. He was instrumental in developing lifting body aircraft, wingless vehicles capable of controlled atmospheric reentry, and remotely piloted research vehicles, both of which have had a lasting impact on aerospace engineering.

Reed’s innovations included the M2-F1 Lifting Body, which demonstrated the feasibility of wingless reentry vehicles, and the Hyper III, the first remotely piloted research vehicle with a ground-based test pilot fully integrated via radio uplink. Reed’s vision extended to planetary exploration, as seen in his patented Mini-Sniffer Mars airplane concept, which anticipated the need for aerial reconnaissance on other worlds.

Today, the Dale Reed Lab continues this legacy by providing cost-effective, flexible platforms for testing new aerodynamic concepts and technologies. The lab enables rapid prototyping and risk reduction, increasing technology readiness for NASA’s missions. This approach, rooted in Reed’s insight that subscale testing yields valuable data with minimal risk, remains central to Armstrong’s research strategy.

“The laboratory enables rapid prototyping and risk reduction before transitioning to full-scale or crewed flight testing, playing a crucial role in increasing technology readiness levels to support NASA’s diverse mission portfolio.”

Current Aircraft Development Project

The latest project at the Dale Reed Lab is the construction of a new subscale aircraft, designed to replace the aging MicroCub. Developed by Justin Hall and Justin Link, the new aircraft reflects a collaborative approach that combines piloting expertise with engineering innovation. By modifying an existing kit, they are adding a more powerful engine, advanced autopilot, comprehensive instrumentation, and a reinforced structure to meet the demands of experimental flight testing.

Measuring 14 feet from wingtip to wingtip and 9.5 feet in length, and weighing around 60 pounds, the new aircraft strikes a balance between capability and manageability. Its enhanced payload capacity supports sophisticated instruments and experimental equipment, making it suitable for a wide range of research applications, from basic aerodynamic studies to complex systems integration.

The integration of a powerful engine and autopilot system increases performance and operational flexibility, while the reinforced structure ensures durability and safety. Real-time data collection and analysis are made possible by the advanced instrumentation, allowing for immediate feedback and rapid iteration of test parameters. These enhancements position the new aircraft as a versatile and reliable platform for NASA’s evolving research needs.

Technological Capabilities and Innovation

The Dale Reed Lab’s technological capabilities reflect a sophisticated blend of modern manufacturing, instrumentation, and research methodologies. With in-house laser cutting, water jetting, and composite fabrication, the lab can rapidly produce custom aircraft tailored to specific experiments. This flexibility enables the swift transition from concept to flight testing, reducing development cycles and fostering innovation.

Safety and scientific rigor are maintained through established design reviews, structural analyses, and risk assessments. One notable innovation is the development of magnetic release mechanisms, which offer advantages over traditional mechanical systems, such as fewer parts, reduced maintenance, and improved reliability. These programmable magnets, tested for extreme conditions, are particularly relevant for space missions where dust and debris can impair mechanical systems.

Another cutting-edge project is the Robust Autonomous Aerial Recapture system, which uses advanced sensors, video processing, and programming to enable mid-air drone capture and deployment. This technology could support mothership-drone operations for science missions, allowing drones to collect samples, recharge, and redeploy efficiently. The integration of artificial intelligence and machine learning further enhances the adaptability and performance of these subscale platforms.

“The integration of artificial intelligence and machine learning technologies into subscale aircraft operations represents a cutting-edge development that could transform aerospace research methodologies.”
