ADAM · Flying Testbed
Lilith UAV
The airframe that proves the ADAM powerplant in flight.
Overview
Our proof that ADAM flies.
Lilith is our flying testbed, an 18 kg fin-stabilized VTOL UAV built to demonstrate the ADAM hybrid microturbine in a real airframe. It combines vertical takeoff with sustained high-speed cruise, reaching Mach 0.62 and roughly 100 km of range without the weight penalty of large battery packs.
Lilith exists to prove the powerplant, not to compete as a product. It takes off from constrained sites, transitions to fixed-wing performance in flight, and runs sensors and payloads entirely off ADAM's onboard generation. It's the same VTOL-plus-jet-cruise package we sell to UAV manufacturers as a drop-in unit.

Flight Architecture
Three States. One Platform.
Lilith moves between these states in the air. No landing, no reconfiguration.
Vertical Takeoff & Landing
eVTOL
Props vertical, full electric lift. Zero runway required. Precise station-keeping with active stabilization in any environment.
Drone-Assisted Flight
Precision
Quadcopter-level control authority at low speed. Exact positioning and attitude hold across all axes, as precise as any multirotor.
> Mach 0.3 · Props Fold
Cruise
Above Mach 0.3, props fold flush for a clean aerodynamic profile. High-speed sustained cruise with no drag penalty.

4×
Speed advantage over comparable sub-25kg platforms (Mach 0.62 vs Mach 0.15)
2×
Range advantage over the sub-25kg class average (100km vs ~44km)
43×
Energy density advantage over battery-powered equivalents
Where Lilith Goes Next
A drone interceptor, on the same airframe.
Everything that makes Lilith a good testbed is exactly what a counter-UAS interceptor needs: vertical launch with no rail or runway, a Mach-class dash, and onboard power for a seeker. Electric-prop interceptors can launch vertically but can't dash; bare turbojets can dash but can't launch vertically or power a seeker. Lilith, built around ADAM, does all three.
It's a next step, not today's product. Defense end-users keep asking for an attritable, mass-producible interceptor, and this platform makes one viable. We're exploring it while we mature the powerplant.
