Beehive Industries Completes Frenzy 6 Engine Tests

Beehive Industries Completes Frenzy 6 Ground Tests Ahead of 2027 Flights

Propulsion startup Beehive Industries finished ground tests of its Frenzy 6 small turbojet engine prototype at its Denver facility, Aviation Week reported. The tests for the 100 lb.-thrust engine wrapped up just four months after Beehive finalized performance milestones, paving the way for flight tests planned for 2027.

The ground testing follows an earlier high-altitude test campaign for a 200 lbf variant of the Frenzy engine family, which Beehive Industries announced on December 8, 2025. That earlier testing took place at a government facility in Ohio and validated engine performance, ignition, operability, and durability across the full flight envelope.

High-Altitude Testing Validates Full Flight Envelope Performance

During the Ohio altitude campaign, two prototype engines shipped in October met or exceeded Air Force requirements, according to Beehive Industries. The tests demonstrated successful ignition across the flight envelope, rapid acceleration from light-off to 100% engine speed, and turbine temperatures and thrust-specific fuel consumption that performed better than predicted.

David Kimball, Chief Technology Officer at Beehive Industries, stated that the milestones confirm the engine’s readiness for flight integration. “In less than a year, we’ve gone from concept to proven high-altitude performance,” Kimball said in a company release, adding that the hardware condition remained “like new” after running for a mission-life equivalent runtime.

Manufacturing Approach Shapes Rapid Development Timeline

Beehive attributes its compressed development schedule to an additive-first manufacturing approach. This method aims to shrink traditional aerospace development cycles from years down to months while delivering disruptive cost and performance at unmatched scale.

With high-altitude trials concluded and ground testing of the Frenzy 6 prototype finished in Denver, Beehive is preparing production capacity across its facilities in Denver, Cincinnati, and Knoxville. The company plans to integrate the engine with its first flight vehicle prior to entering low-rate initial production.

Frequently Asked Questions About the Frenzy Engine Program

What is the primary application for the Frenzy engine family?

The engines are designed to power next-generation uncrewed aerial defense applications and uncrewed aerial systems.

Which government entities backed the initial development of the engine?

The program received backing from a $12.46 million contract awarded in October 2024 by the U.S. Air Force Rapid Sustainment Office in partnership with the University of Dayton Research Institute.

Where does Beehive Industries manufacture and test its propulsion systems?

The company operates facilities in Denver, where it runs ground tests, alongside sites in Cincinnati and Knoxville, with altitude testing conducted at a government facility in Ohio.
