MARSS Interceptor
The MARSS Interceptor is an unmanned aerial vehicle (UAV) designed by MARSS Group for counter-unmanned aerial systems (C-UAS) use. Interceptor-MR The Interceptor Medium Range was first displayed in March 2022. It is designed as a hard-kill countermeasure that rams hostile drones, using kinetic energy to destroy them rather than an explosive warhead, which would be more restrictive in places like urban areas. The air vehicle is electrically powered and is propelled by four ducted fan rotors, two larger fans on the top and underneath providing thrust and two smaller fans at the wingtips for steering. This propulsion system enables it to achieve a top speed of 80 m/s (288 km/h; 155 knots). It originally had an overall weight of which was later reduced to 8.5 kg and a wingspan of 90 cm. The fuselage is made of carbon fiber and polymer with titanium to reinforce the forward part as well as inserts in the wing leading edges and in the front part of the rotor n ...

Ducted Fan
In aeronautics, a ducted fan is a thrust-generating mechanical fan or propeller mounted within a cylindrical duct or shroud. Other terms include ducted propeller or shrouded propeller. When used in vertical takeoff and landing (VTOL) applications it is also known as a shrouded rotor.Kotwani, Kailash;Ducted Fan or Shrouded Rotor Aerodynamics and its Application in Miniature VTOL Aerial Vehicles, 2009. (retrieved 22 March 2022). Ducted fans are used for propulsion or direct lift in many types of vehicle including aeroplanes, airships, hovercraft, and powered lift VTOL aircraft. The high-bypass turbofan engines used on many modern airliners is an example of a very successful and popular use of ducted fan design. The duct increases thrust efficiency by up to 90% in some cases, in comparison to a similar-sized propeller in free air. Ducted fans are quieter, and offer good opportunities for thrust vectoring. The shroud offers good protection to ground personnel from accidentally cont ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
