Kelvin Wong, Singapore - Jane's International Defence Review UAVOS Inc, a US-based company specialising in the design, development and manufacturing of unmanned vehicles and associated control systems, is partnering with India's Bharat Drone Systems to develop a range of air vehicles and technologies to meet emerging Indian armed forces requirements. The company is taking the opportunity at the UAV India 2018 exhibition in New Delhi to highlight its fixed-wing and vertical take-off and landing (VTOL) unmanned aerial vehicles (UAVs). The fixed wing Borey 10 is a tactical-class UAV featuring a flying wing airframe with a wingspan of 3.5 m and maximum take-off weight (MTOW) of 15 kg. The baseline UAV is powered by a 2,000 W electric motor and four 6S 16Аh lithium-ion (Li-ion) batteries that are packaged within a hermetically sealed shell along with its control systems for improved reliability in austere environments, enabling it to continue operations in temperatures as low as -22 °C. According to UAVOS, the Borey 10 – which features automatic take-off and landing capabilities and can be launched and recovered via a catapult and parachute respectively – is designed to transmit video imagery in difficult meteorological operating conditions at distances over 30 km, with a control range of at least 70 km. The company is quoting a continuous flight endurance of up to 4 hours with a 0.5 kg payload. UAVOS has also developed a range of VTOL UAV platforms. The latest addition is the UVH-290E, which has a maximum take-off weight (MTOW) of 2 107 kg and measures 2.43 m long and 0.86 m tall with a main rotor diameter of 3.2 m. It is equipped with a 4-stroke Wankel engine rated at 17 kW, enabling it to achieve cruise and maximum speeds of 70 km/h and 100 km/h respectively, with a stated endurance of about 5 hours while carrying a 5 kg payload. https://www.janes.com/article/82743/uavos-showcases-latest-uavs
