Click on the following video to quickly get an overview: 
TF-G2 autogyro is well-suited for training UAV operators and for gaining experience with autogyro mission planning. TF-G2 is limited to light payloads, but it shares all the specific properties of larger autogyros in our offering. It may find application in less demanding flight operations, however, its main purpose is to be a tool for low-cost application practice. The autogyro’s small size leads to easy transport, repairs, and maintenance. To enhance the ease of learning autogyro technology, we made it possible to simulate TF-G2 flight before the real flight training.
The main design highlights

Based on that features the TF-G2 is perfectly suitable for atmospheric measurement applications. That could be illustrated by the successful integration of multiple sensor types.
Applications
Here are some examples of existing use cases for TF-G2 as a lightweight sensor carrier. These application-specific use cases extend the integrated sensing possibilities provided by existing autogyro avionics. The inherently existing onboard sensors in avionics are position, time, wind speed direction and velocity, and atmospheric pressure.
Particulate matter sensing
Particulate matter sensing in the atmosphere is a scientific technique used to monitor and measure the concentration of small solid particles suspended in air, often termed aerosols. These particles, typically categorized by their size - such as PM2.5 and PM10 - can originate from various sources including combustion processes, industrial emissions, vehicle exhausts, and natural phenomena like dust storms. Sensing and monitoring particulate matter is crucial for environmental health and public safety, as high levels can severely impact air quality, contributing to respiratory and cardiovascular diseases. Moreover, this data aids meteorological predictions and climate models, as particulates influence atmospheric visibility, and can affect the earth’s radiation balance, hence playing a role in climate change. The TF-G2 autogyro could be equipped by TFPM01 particulate matter sensor to measure the concentration of particulate matter in the specified air volume.
Humidity and temperature sensing
Humidity and temperature sensing in atmospheric vertical sounding involve the measurement of atmospheric moisture content and temperature at various altitudes. Instruments like the TFHT01 sensor from ThunderFly are pivotal in collecting this data. These compact and lightweight sensors, designed specifically for UAV applications, can withstand varied atmospheric conditions and provide accurate, high-resolution measurements. Acquiring this data is essential for meteorological forecasts and climate studies, as the vertical distribution of temperature and humidity influences weather patterns, storm development, and overall climate dynamics. The TFHT01 sensor, with its specialized design and precise data, has become an instrumental tool in advancing our understanding of these complex atmospheric processes.

Electric field monitoring
Electric field monitoring via TF-G2 UAV autogyro near thunderstorms entails the measurement of atmospheric electrical properties associated with storm activities. The charged particles present in thunderstorms create strong electric fields, which can be accurately detected and monitored by THUNDERMILL01 sensor. The TF-G2 autogyro, equipped with specialized sensors, can navigate challenging weather conditions and provide critical, real-time data on the strength and spatial distribution of the electric fields. Understanding these fields is crucial in predicting lightning activity, improving weather forecasts, and contributing to research on storm dynamics and atmospheric electricity. This UAV-autogyro technology offers a unique, mobile platform to safely investigate these intense electrical phenomena without putting human lives at risk.
Ionising radiation monitoring
Ionizing radiation monitoring in the atmosphere involves detecting and quantifying radioactive particles using specialized devices like semiconductor-based ionizing radiation AIRDOS03 spectrometer and dosimeter. This instrument measures the intensity and spectral distribution of ionizing radiation, such as alpha, beta, gamma, and X-ray emissions that can originate from natural sources or human activities. The compact and precise nature of semiconductor-based devices allows for sensitive detection and accurate quantification of radiation levels. Monitoring atmospheric ionizing radiation is vital for assessing environmental radiation hazards, managing nuclear emergencies, and supporting research in fields such as meteorology, geology, and climate science. These advanced devices help ensure public safety and enhance our understanding of natural and anthropogenic radioactive processes in the atmosphere.
