US News To save fuel: Lufthansa wraps Jets in Shark Skin
johan stigefelt: budget planning difficult, but corona also saves money
in times of corona pandemic is the budget planning for a motogp team not easy - some expenses rise, in other areas money is saved The sepang racing team is in All three classes active. In the MotoGP you work together with Yamaha and goes with Valentino Rossi and Franco Morbidelli. In the Moto2 one sets on Kalex and occurs with Xavi Vierge and Jake Dixon. And in the Moto3, John McPhee and Darryn Binder sit on motorcycles from Honda.
Lufthansa Jets should save fuel in the future with the help of a novel surface foil. The surface developed by BASF is modeled by the ribbed skin of sharks, both companies reported on Monday.
With better aerodynamics, the luminaire could be reduced by about one percent, so that annual savings of 3700 tons of kerosene are possible when using the entire Lufthansa freighter fleet. Thus, the emission of around 11,700 tonnes of climate-damaging carbon dioxide (CO2) would avoided, which corresponds to around 48 cargo flights from Frankfurt to Shanghai.
Space: Out of the ISS - Putin wants to build Russian space station

She should also work without cosmonauts. © Picture Alliance / NASA The cooperation still works: Two Russian spaceships are docked to the international space station. The cooperation between Russia and the West arrived almost everywhere at the zero point.
Lufthansa wants to equip all freighter aircraft with
from the coming year all the freighters of Lufthansa Cargo, ten jets of type Boeing 777, with the new film should be glued. It's about the bottom of the hull to the side surfaces where no disturbing window rows are available for freighters. Also parts of the wing would be glued, reported a spokesman for Lufthansa Technik. Overall, it is about 800 square meters shark skin per aircraft.
So far, the film has been tested on around 500 square meters on the submerged of a Boeing 747-jumboos. For this, Lufthansa Technik had also achieved the approval by European flying safety EASA.
Lufthansa Technik and BASF intend to develop the new technology consistently towards additional aircraft types and even larger areas. In first model calculations, shark skin technology was able to avoid up to 3 percent of CO2 emissions, the companies explained. (dpa)
