‘Stealth Sheet’ Makes People And Vehicles Invisible To Drones By Suppressing Infrared Light

The stealth sheet was created by researchers that hope it will be used in battle. As weapons become more sophisticated with the advances in technology, so do the countermeasures to weapons. Researchers at the University of Wisconsin-Madison have invented the “stealth sheet,” which is a super thin sheet that can suppress infrared light. This can be used to mask people and vehicles that emit infrared light, which can normally be picked up by drones, heat-sensing night vision goggles, and infrared cameras, according to the Daily Mail. The stealth sheet is made out of a bendable silicon material, masks up to 94 percent of infrared light, and is only a millimeter wide. The co-author of the study, Hongrui Jiang, described the concept behind the invention. “You can intentionally deceive an infrared detector by presenting a false heat signature … It could conceal a tank by presenting what looks like a simply highway guardrail.” So far, the stealth sheet has been tested with a model of the hu…

Sino-Russian widebody gets seven proposals for engine

CRAIC engine ile ilgili görsel sonucu




Developers of the Chinese-Russian widebody have received proposals from seven firms to supply the aircraft’s propulsion system.
The submissions were made to the China-Russia Commercial Aircraft Corporation (CRAIC) as according to the 30 May deadline. The bids came from both domestic and foreign suppliers, says Chinese airframer Comac.
CRAIC issued the request for proposal last December. Last week, Sukhoi Civil Aircraft, the commercial aviation unit for United Aircraft, told FlightGlobal that the developers of the aircraft have increased the engine thrust required for the jet. The requirement is now for 78,000lb-thrust turbofans, up from the previous 75,000lb-thrust specification.
“It has changed because of marketing demand that the aircraft be able to base in several high-altitude aerodromes in China. After the answer to RFP requests from potential engine suppliers is received, this measurement might also be elaborated,” it adds.
CRAIC says it will analyse, clarify and evaluate the proposals received by the end of the year. Rolls-Royce and General Electric are expected to be among the seven which have submitted bids.
United Aircraft and Comac are developing three variants of the twinjet. The baseline model will be the CR929-600 with a passenger capacity of 281 seats in a three-class configuration, and a range of 12,000km.
