ThunderFly TF-G2 is a UAV of autogyro type designed and manufactured in the Czech Republic. The first flight took place in May 2020. Its primary use involve simpler flight operations under adverse weather conditions, supporting applications from scientific research[1] to air pollution monitoring.[2] Thanks to the open-source design and the use of 3D printing technology it can be easily modified for a specific application.[3][4] A key feature of the TF-G2 autogyro is its ability to fly in strong winds with wind gusts (or more generally, to fly under severe meteorological conditions) setting it apart from similar-sized multicopters or aircraft that are not capable of such flights due to safety reasons. Another important feature of autogyro is an autorotation safety mode that enables a controlled (slow) descent even in the event of avionics failure.[5]
Use and control
The unmanned autogyro TF-G2 is remotely controlled from a ground station by a pilot and a flight operator. It is possible to do so in an assisted mode, when the pilot determines the direction of the flight and the integrated avionics takes care of flight parameters. An automated mode is also available, when way-points generated by the control system enable automatic take-off, flight and landing. TF-G2 also possesses safety mode that allow it to return to a take-off site or land in a safe area in case of communication loss or other failure.[6][7]
To practice specific use of TF-G2 a simulation model for FlightGear simulator is available.[8]
Take-off methods
TF-G2 unmanned autogyro's construction and design makes it possible to take-off from the roof of a car, which, at the same time, serves as a ground control station.[9] In this method, the car is used for achieving necessary rotor speed (revolutions) as it is driven along. Alternatively, the autogyro can take-off via throwing it from a hand. The necessary rotor revolutions are achieved during a short sprint. This take-off method is advantageous in that it does not need any additional equipment.[10]
Communication and monitoring
TF-G2 autogyro uses a radio transmission with a MAVLink protocol to communicate with a ground station. At the same time, the data link is used to transmit data from sensors during carrying out flight tasks thanks to a set of open-source tools TF-ATMON.[11] This system enables to connect different sensors to the autogyro's avionics and at the same time make use of an already existing power supply and radio data transmission channel. The solutions facilitates minimization of payload's weight (e.g. measuring apparatus).[12]
Technical parameters
- Maximum takeoff weight: 1.5 kg
- Electric engine BLDC
- 3D printed design (Fused filament fabrication technology)
- Airspeed flight range: 7-25 m/s
- Wind gust resistance: up to 10 m/s
- Payload capacity: 100g
Payload
TF-G2 unmanned autogyro is designed to support the installation of a wide range of sensors for measuring atmospheric quantities. Apart from the mechanical design, this is supported by its electronics and software adapted for easy transmission of measured values to the ground station. The values are displayed in a form of a real-time interactive spatial map. Consequently, the flight trajectory can be easily adapted based on the measured data in order to effectively re-measure the places of interest. Examples of used measuring devices[13]
- Particulate matter sensor[14]
- Temperature and humidity sensor[15]
- Electric field sensor[16]
- Semiconductor detector of ionizing radiation[17]
Areas of use
TF-G2 is designed both as a training autogyro for pilots and operators of larger unmanned autogyros and as an aircraft able to withstand and fly under adverse meteorological conditions. Thanks to its parametric design and an ability to carry light detectors it is easily modifiable for specific purposes and tasks, e.g. atmospheric measurements.[18]
Due to the above mentioned characteristics, it is for example used to monitor atmospheric pollution[19], or to measure electric field in storm clouds[20] .
