REYNS™ aerodynes are fully autonomous, battery-powered UAVs that deliver superior aerodynamic performance, payload capacity and endurance. The aerodyne propulsion is closely connected to and cannot be dissociated from the proposed navigation system, offering an airframe that is virtually invulnerable to obstacle impact and is able to hold altitude without being damaged in a hostile environment. According to our understanding, the propulsion system is by far the most essential component of a UAV, having a determinant influence on decision-making for adoption and deploying.

So far, there have been considered two different propulsive devices:

1. Turbo-Drone, which uses the Coandă effect, a classic fluid mechanics principle that has inspired numerous heavy-lift VTOL and anti-torque system developments, to create a lower pressure distribution on the top of a stationary revolved airfoil; and

2. Jet-Drone, which adapts a compressor section of a generic jet engine design, and uses a high-RPM motor to turn an extra-efficient turbofan.

​Besides the propulsion, there are few truly unique innovations discernable in the designs of REYNS™ autonomous aerodynes, as follows:

• VPNS (Visual Positioning Navigation System) through geo-referential odometry - an autonomous navigation method designed as a functional backup to both GPS and inertial navigation systems;

• Designs of Photovoltaic (PV) Cells and Thermal Energy Devices (TED), which are placed on relevant airfoil/airframe surfaces, for improved safety, reliability and endurance; unlike conventional propeller-driven UAVs, REYNS™ aerodynes feature ideal configurations for adapting the PV thin film cells and TEDs to curved and/or flexible substrates for maximizing the power generation.

Our systems' convertibility, i.e. system’s ability to adapt to multiple applications, allows for rapid conversions of the GPiR antenna-to-airframe interface. These enable fitting of GPiR and numerous other categories of unusual sensors, customizing them as landing gear too, for subsurface scanning of either horizontal or sloped or vertical structures.
