Beehive Industries Tests Frenzy 6 Engine

Key Takeaways

• Beehive Industries completed testing of its Frenzy 6 turbine (100 lbf ≈ 450 N) in just four months after contract award.
• The engine is being positioned for UAVs, loitering munitions, interceptor drones, and small‑strike missiles, and may serve as a U.S. counterpart to the Russian Geran‑5 jet drone.
• Development is funded by a $29.7 M U.S. Air Force program that also backs the broader Frenzy family of engines.
• Additive‑manufacturing (AM) enables rapid design iteration, lower unit cost, and scalability for high‑volume defense production.
• Compared with the larger Frenzy 8, the new model delivers similar performance in a more compact package, targeting lower‑cost, high‑mix platforms.

Introduction

Beehive Industries, a U.S.‑based aerospace supplier, announced the successful ground‑test of its Frenzy 6 turbine engine. Rated at 100 lbf (≈ 0.45 kN) of thrust, the engine is intended for a spectrum of unmanned aerial systems (UAS) ranging from loitering munitions to small strike missiles. The test marks the culmination of a four‑month development cycle under a $29.7 million U.S. Air Force contract that also funds the larger Frenzy 8 and other members of the Frenzy engine family.

Program Timeline & Funding

The compressed schedule demonstrates the advantage of additive‑enabled design, which eliminates traditional tooling lead times and allows simultaneous design‑for‑manufacture iterations.

Technical Highlights of Frenzy 6

The Frenzy 6 leverages a single‑spool axial‑flow architecture with a high‑temperature ceramic‑coated turbine. The use of laser powder‑bed fusion (LPBF) for critical hot‑section components reduces cycle time from weeks to days and enables internal cooling channel geometries that are impossible with subtractive methods.

Strategic Fit for the U.S. Air Force

The Air Force is currently fielding platforms such as the Miniature Air‑Launched Decoy (MALD), Golden Horde swarming munitions, and various missile trainer concepts. The Frenzy 6’s compact size and low‑cost production align with the service’s high‑mix, low‑cost acquisition strategy:

• MALD‑compatible: Provides sufficient thrust for rapid climb and loiter phases.
• Swarming munitions: Enables each node in a swarm to carry its own propulsion, improving range and survivability.
• Missile trainers: Offers a reusable, low‑cost propulsion source for reusable target drones.

Comparison with Frenzy 8

Both engines share the same additively enabled design philosophy, but the Frenzy 6 is deliberately trimmed to meet the mass‑sensitive envelope of emerging micro‑UAS.

Leadership Perspective

• David Kimball, CTO emphasized that the Frenzy 8 validation “proved the speed of our additive workflow,” which directly accelerated Frenzy 6 development. He highlighted “class‑leading performance and altitude‑start capability” as transferable assets.
• Gordie Follin, CPO framed the engine as a “compact, affordable powerplant” designed to “enable mass production for U.S. defense” and to “deliver speed, performance, cost, and scale” through additive manufacturing.

Bottom Line

Beehive Industries’ Frenzy 6 demonstrates that a 100 lbf turbine can be designed, fabricated, and flight‑tested within a four‑month window thanks to an additive‑manufacturing‑centric development model. With a lightweight, low‑cost architecture and performance comparable to its larger sibling, the engine is poised to power the next generation of U.S. UAVs, loitering munitions, and swarming weapons. The $29.7 M Air Force investment not only validates the technology but also sets a precedent for rapid, high‑volume delivery of propulsion solutions in a contested future.
