Abstract: The results of catapult launching tests of unmanned aerial vehicles (UAVs) with power plants based on one and two paired ramjet pulsed detonation engines (PDEs) are presented. The world’s first autonomous flight of an UAV with a new type of ramjet power plant is demonstrated. The power plant includes an air intake with a mechanical check valve and detonation tube and is fueled by hydrocarbon fuels including regular aviation kerosene. At the speed of the approaching air flow from 30 to 120 m/s, the power plant provides the effective thrust up to 250 N with a fuel-based specific impulse of 1000–1200 s. The results of catapult launching tests of UAVs with a takeoff mass of up to 100 kg have shown that the PDE-based power plants provide a subsonic flight with acceleration and climbing. Due to the simplicity of design and low cost, as well as high propulsion performances, such power plants can be considered as an alternative to the propulsion units based on piston and turbojet engines for subsonic UAVs.
Keywords: pulsed detonation engine; power plant; experimental sample; catapult launching tests; thrust performance; specific impulse

India’s Rustom-2 UAV gets massive upgrade, will soar to 27,000 feet in April


Rustom-2, India’s medium-altitude long-endurance drone being developed by the Defence Research and Development Organisation, is targeted to achieve a huge milestone in April when it will take off from its test range in Karnataka’s Chitradurga to fly for more than 18 hours at a height of over 27,000 feet, people familiar with the development said.

Rustom-2, also known as Tapas-BH (Tactical Airborne Platform for Aerial Surveillance-Beyond Horizon 201), successfully completed the last flight test in October last year when it successfully flew for eight hours at an altitude of 16,000 feet.

“This will be a huge step,” said a senior government official about the indigenously-developed unmanned aerial vehicle (UAV) designed for strategic reconnaissance and surveillance operations. Rustom-1

Iska to airframe hi turkish hoga thoda bohot .
I posted it on Dephencehub and Turks called it Greek/Armenian Sazish and said that older variants for R&D had so much imported components while the production variant has mostly Turkish parts.
