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.

Radiate Engineering & Design AG | Hohlstrasse 176 | CH – 8004 Zürich | www.radiate.ch

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.
