TEL AVIV, Feb 2 (Reuters) - Israeli armed drones use gravity bombs that produce no noise or smoke as they fall, making them hard for enemies to anticipate or evade, and the largest model of the aircraft can carry up to a tonne of munitions, the military says. After more than two decades of secrecy, Israel in July went public with the existence of armed drones in its arsenal. The former, the officer said, "is the heaviest drone that the IDF (Israel Defence Forces) has, which can carry munitions, with an effective payload of around a tonne". The Israeli manufacturers do not publicise the armed capabilities of the drones, under what industry sources have described as a Defence Ministry secrecy policy. All the drone munitions are Israeli-made, the officer said, and "come down in free-fall, and can reach the speed of sound".

☆ NASA awards $425 mln to Boeing for fuel-efficient airliner research project

WASHINGTON, Jan 18 (Reuters) - NASA said on Wednesday it awarded $425 million to Boeing Co (BA.N) for the agency's "Sustainable Flight Demonstrator" project as the Biden administration works to cut aviation sector emissions. Boeing will work with NASA to "build, test, and fly a full-scale demonstrator aircraft and validate technologies aimed at lowering emissions," the agency said. Over seven years, NASA will invest $425 million, while Boeing and its partners will contribute the remainder of the agreement funding, estimated at about $725 million. Single-aisle aircraft account for nearly half of worldwide aviation emissions. The White House is targeting 20% lower aviation emissions by 2030, as airlines facing pressure from environmental groups to lower their carbon footprint pledged to use more sustainable aviation fuel.

NASA has selected Boeing and its industry team to lead the development and flight testing of a full-scale Transonic Truss-Braced Wing (TTBW) demonstrator airplane. NASA said on Wednesday it awarded $425 million to Boeing for the agency's "Sustainable Flight Demonstrator" project as the Biden administration works to cut aviation sector emissions. Boeing will work with NASA to "build, test, and fly a full-scale demonstrator aircraft and validate technologies aimed at lowering emissions," the agency said. Over seven years, NASA will invest $425 million, while Boeing and its partners will contribute the remainder of the agreement funding, estimated at about $725 million. The "Transonic Truss-Braced Wing" demonstrator single-aisle airplane aims to reduce fuel consumption and emissions by up to 30%.

The first full-color image released from the next-generation James Webb Space Telescope is the sharpest infrared image of the distant universe ever produced, according to NASA. Space Telescope Science Institut / NASA, ESA, CSA, STScI, Webb ERONASA released the first batch of images from the tennis court-sized observatory to much fanfare in July.

Back to the moonFifty years after the final Apollo moon mission, NASA took key steps toward returning astronauts to the lunar surface. Chinese officials have also said they intend to use the space station for space tourism and commercial space initiatives.

Dec 17 (Reuters) - L3Harris Technologies Inc (LHX.N) is nearing a $4.7 billion deal to acquire U.S. rocket maker Aerojet Rocketdyne Holdings Inc (AJRD.N), 10 months after the latter's $4.4 billion sale to Lockheed Martin Corp (LMT.N) fell through, people familiar with the matter said on Saturday. L3Harris is a defense contractor that is mostly a competitor rather than a customer of Aerojet. Aerojet's solid fuel rocket motors and other propulsion systems would help L3Harris expand its space defense systems and precision munitions businesses. Spokespeople for Aerojet, L3Harris and General Electric did not immediately respond to requests for comment. Its customers include the Pentagon, Boeing (BA.N), Lockheed Martin and Raytheon Technologies Corp (RTX.N).

☆ Pentagon debuts its new stealth bomber, the B-21 Raider

The B-21 Raider is the first new American bomber aircraft in more than 30 years. Both the Air Force and Northrop also point to the Raider's relatively quick development: The bomber went from contract award to debut in seven years. And we will build the bomber force in numbers suited to the strategic environment ahead," Austin said. The B-21 Raider, which takes its name from the 1942 Doolittle Raid over Tokyo, will be slightly smaller than the B-2 to increase its range, Warden said. Northrop Grumman has also incorporated maintenance lessons learned from the B-2, Warden said.

☆ Rolls-Royce uses hydrogen produced with wind and tidal power to test jet engine

The test used a converted regional aircraft engine from Rolls-Royce, with hydrogen produced at the European Marine Energy Centre in Orkney. LONDON — Plans to reduce the significant environmental effects of aviation took a step forward this week after Rolls-Royce and easyJet said they had carried out the ground test of a jet engine that used hydrogen produced from tidal and wind power. The test, which was carried out at an outdoor site in the U.K., used a converted regional aircraft engine from London-listed Rolls-Royce. "This is a true British success story, with the hydrogen being used to power the jet engine today produced using tidal and wind energy from the Orkney Islands of Scotland," Shapps added. Using hydrogen to power an internal combustion engine is different to hydrogen fuel cell technology, where hydrogen from a tank mixes with oxygen, generating electricity.

☆ GM investing $760 million in Toledo factory to make electric car drive units
▼ + stars: | 2022-09-23 | by ( Peter Valdes-Dapena | Cnn Business | ) edition.cnn.com time to read: +1 min

(CNN) General Motors is investing $760 million in its Toledo Propulsion Systems factory, which builds transmissions for gas-powered vehicles, so that it can make electric drive units for electric vehicles, too. The drive units will be used in GM electric trucks, the automaker said, including the GMC Hummer EV, which is currently in production, and the upcoming Chevrolet Silverado EV and GMC Sierra EV. It will be GM's first US engine or transmission factory adapted for electric vehicle-related production. Electric drive units include an electric motor, one-speed transmission and power electronics that bring power to and from the motor. For the now, at least, the factory will continue building transmissions for front- and rear-wheel-drive gas-powered vehicles along with the electric drive units, GM spokesman Dan Flores said.

REUTERS/Rebecca CookToledo, OHIO/WASHINGTON, Sept 23 (Reuters) - General Motors Co (GM.N) said Friday it will invest $760 million at its Toledo, Ohio factory to build drive units for electric trucks, the automaker's first U.S. powertrain facility repurposed for EV-related production. Congress in August approved significant financial incentives for automakers to convert plants producing parts for gasoline-pore vehicles to electric models. Many autoworkers have expressed concerns about the shift to EVs and if it would impact current auto employment.
