Radiate Engineering & Design introduces FlyBlocks – a production-ready structural airframe platform for long-range VTOL UAV applications
Radiate Engineering & Design AG, based in Zurich, introduces FlyBlocks, a production-ready structural airframe platform for professional B2B VTOL UAV applications, with a focus on long-range and endurance-driven missions. With FlyBlocks, UAV companies start from a validated and controlled structural and aerodynamic foundation and move directly into system integration, mission validation, and operational deployment.
Many UAV companies are strongest in mission systems, technical operations, and application-specific deployment. What often slows them down is the need to develop an airframe from scratch. It must be structurally sound, aerodynamically efficient, and reproducible in industrial production — especially for applications that require efficient long-range operation. At the same time, the market is demanding more transparency, documentation, and European-based sourcing. FlyBlocks is designed to simplify this path.
Built on Radiate’s engineering experience across numerous UAV development projects, FlyBlocks provides a standardized, production-ready structural airframe architecture developed through a closed-loop approach of simulation, manufacturing, and validation. UAV programs build on a defined structural backbone and aerodynamic baseline, while integrating their own autopilot, avionics, sensors, propulsion configuration, and payload.
A modular fuselage concept with defined Payload Interface Modules (PIM) enables mission-specific adaptation without altering primary structural elements. This allows multiple applications to be realized on a common platform while maintaining a consistent and controlled configuration baseline, including missions requiring extended range and endurance.
FlyBlocks Lineup
FlyBlocks is introduced with a scalable lineup of VTOL platforms, built on a common structural and aerodynamic architecture:
FLY-VT14
VTOL 1.4 m wingspan | ~5 kg MTOW | ~0.6 kg payload | ~100 km range
Compact platform for lightweight sensor missions and high operational flexibility.
FLY-VT22
VTOL 2.2 m wingspan | ~12–14 kg MTOW | ~2–3 kg payload | ~150 km range
Mid-size platform balancing endurance and payload capability.
FLY-VT30
VTOL 3.0 m wingspan | ~25–28 kg MTOW | ~5–8 kg payload | ~180 km range
Extended mission platform for higher payload classes and longer operational profiles.
All platforms share the same structural design philosophy, interfaces, and development approach, enabling scalability across missions while maintaining consistent performance and integration logic.
Controlled European-based supply chain
A key advantage of FlyBlocks lies in its controlled European-based sourcing and manufacturing pathway. Critical structural elements are developed and controlled in-house, supported by qualified partners, defined processes, and structured documentation. Material and process traceability are integrated from the outset, and all delivered components are supported by traceable documentation and certificates of conformity.
At a time when many airframes rely on opaque sourcing structures and limited configuration control, FlyBlocks offers a documented, repeatable, and European-based alternative designed for industrial consistency.
Developed with certification in mind
FlyBlocks is developed with a certification-oriented engineering approach from an early stage. The platform includes defined load cases, structural design methodology, and a compliance-oriented documentation structure.
A structural substantiation basis is available, reflecting the underlying analysis, design rationale, and validation approach of the platform. The extent and final form of the substantiation depend on the specific mission profile, system configuration, and operational requirements, and can be further refined within dedicated engineering scopes.
FlyBlocks is not delivered as a fully certified UAV system. Customers remain responsible for system integration, aircraft-level validation, and operational approval. However, the platform provides a stable structural foundation that significantly reduces the effort required for compliance, validation, and certification.
From engineering partner to platform provider
With FlyBlocks, Radiate expands its role in the UAV market from engineering partner to platform provider.
“FlyBlocks represents a natural next step for Radiate,” says Timothy Habermacher, Head of the UAV Division at Radiate Engineering & Design. “Over many UAV projects, we have built deep know-how in structures, aerodynamics, prototyping, industrialization, and certification-oriented development. With FlyBlocks, this experience becomes a platform: customers build on a well-defined and engineering-sound structural foundation and focus on the mission system that differentiates their UAV.”
Showcase at XPONENTIAL Europe | Market introduction in Q3 2026
FlyBlocks will be showcased publicly for the first time at XPONENTIAL Europe 2026 in Düsseldorf, taking place from 24–26 March 2026, where Radiate will exhibit in Hall 1, Booth E03.
Currently undergoing final validation and industrial preparation, FlyBlocks anticipates its market introduction in the third quarter of 2026.
