Beehive’s 3D-Printed Frenzy Engine Advances Toward 2026 Flight Tests

Beehive’s 3D-Printed Frenzy Engine Advances Toward 2026 Flight Tests
High-Altitude Testing Marks a Key Milestone
Additive manufacturing is revolutionizing military propulsion by drastically shortening the timeline from engine design to testing. This rapid development cycle aligns with the Pentagon’s objective to deploy quickly produced powerplants for a new generation of uncrewed aircraft. In this context, Beehive Industries has reached a significant milestone with the successful completion of high-altitude testing for its 200-pound-thrust, 3D-printed Frenzy engine, developed specifically for the US Air Force.
The recent tests, conducted at a government facility in Ohio, represent a crucial step toward the engine’s planned flight trials in early 2026. Frenzy belongs to a new class of small jet engines created almost entirely through advanced digital modeling and additive manufacturing. This approach enables rapid prototyping, iterative modification, and streamlined production. Building on the success of Beehive’s earlier Rampart engine, Frenzy exemplifies the Pentagon’s pursuit of scalable propulsion solutions tailored for uncrewed systems.
David Kimball, Chief Technology Officer at Beehive Industries, highlighted the significance of this achievement: “This milestone confirms Frenzy’s readiness for flight integration. In less than a year, we have gone from concept to proven high-altitude performance, ahead of schedule, thanks to our talented and determined team. Frenzy is now flight-ready, and our production system is prepared to scale alongside it.”
Accelerated Development and Test Outcomes
Beehive’s development timeline for the Frenzy engine has been notably compressed. Within four months, the company completed ground tests on six engines before shipping two prototypes to Ohio for altitude trials. During these tests, engineers assessed ignition behavior, low-pressure stability, fuel consumption, and thermal performance under demanding conditions.
The engines demonstrated reliable ignition and operation across the full flight envelope, achieving rapid acceleration from light-off to full power. Turbine temperatures and fuel consumption metrics exceeded initial predictions, while the hardware remained in “like new” condition after runtime equivalent to a full mission life. These results are particularly significant given the unique stresses imposed by high-altitude environments on small turbine engines. Stable ignition and smooth acceleration are critical factors, especially for engines intended for high-volume, cost-sensitive uncrewed platforms.
Kimball emphasized that the test campaign validated not only the engine’s capabilities but also Beehive’s broader development philosophy. “We are not just accelerating development timelines; we are ensuring America’s warfighters have the technology they need, when they need it most,” he stated.
Future Challenges and Industry Implications
Looking ahead, Beehive faces the challenge of integrating the Frenzy engine with its flight test vehicle and addressing any technical issues that may arise during upcoming flight trials. The successful demonstration has already attracted heightened interest from defense contractors and potential customers focused on autonomous fighter jets.
This achievement is also expected to intensify competition within the industry. Major players such as Pratt & Whitney, GE Aerospace, Rolls-Royce, and Honeywell Aerospace are anticipated to accelerate their own engine development efforts, targeting the emerging market for autonomous military aircraft.
Beehive’s “additive-first” strategy—emphasizing rapid cycles of printing, testing, refining, and reprinting engine components—continues to define its development pipeline. As the defense sector moves toward high-volume, rapidly evolving uncrewed systems, Beehive’s approach positions the company at the forefront of next-generation propulsion innovation.
