A Vertical take-off and landing (VTOL) capability brings aircraft a lot of mobility and convenience, especially in difficult terrain conditions. It enables the UAV usage in confined space, inside compounds and urban conditions. It also aids the operations in the natural environment like forests or mountain areas. Foremost it can be operated from a battleship or a rescue vessel. The trend in the industry is to implement VTOL capability to bigger UAVs.

The Estonian Threod Systems company has unveiled its new unmanned aerial vehicle (UAV) with VTOL capabilities.

Stream C is perceived as NATO class I UAV that fulfills the class II roles. It is a 35kg maximum take-off weight UAV that operates over 100km line-of-sight range and detects a vehicle at 15km.

The company released footage on social media, saying: “We are proud to announce that Threod Systems has successfully integrated VTOL capability into our NATO class I UAV Stream C. The transition algorithms and VTOL-fixed wing functions have been developed in-house for Threod’s proprietary autopilot.”

The first public presentation of Stream C VTOL will be in February 2019, according to the company website.

Threod Systems specializes in developing, producing, and operating UAVs that are designed for information collection and exploitation in military, governmental and civil applications, according to defence-blog.com.
