NASA Research Could Save Global Commercial Airlines over a trillion dollars between 2025 and 2050

http://ift.tt/hZ0OVi
The nation’s airlines could realize more than $250 billion dollars in savings in the near future thanks to green-related technologies developed and refined by NASA’s aeronautics researchers during the past six years.

These new technologies, developed under the purview of NASA’s Environmentally Responsible Aviation (ERA) project, could cut airline fuel use in half, pollution by 75 percent and noise to nearly one-eighth of today’s levels.

“If these technologies start finding their way into the airline fleet, our computer models show the economic impact could amount to $255 billion in operational savings between 2025 and 2050,” said Jaiwon Shin, NASA’s associate administrator for aeronautics research.

US jet fuel usage will be less than 25% of the world total for 2025 to 2050. Therefore the world will save over a trillion dollars from 2025 to 2050 by all airlines adopting the NASA aerodynamic improvements.

Researchers with NASA's Environmentally Responsible Aviation project coordinated wind-tunnel tests of an Active Flow Control system -- tiny jets installed on a full-size aircraft vertical tail that blow air -- to prove they would provide enough side force and stability that it might someday be possible to design smaller vertical tails that would reduce drag and save fuel.

Spacex upgraded the Merlin Rocket Engines

http://ift.tt/hZ0OVi
In 2015, SpaceX made a number of modifications to the existing Falcon 9 v1.1. The new rocket was known internally as Falcon 9 v1.1 Full Thrust, and is also known as Falcon 9 v1.2, Enhanced Falcon 9, and Full-Performance Falcon 9.

A principal objective of the new design was to facilitate booster reusability for a larger range of missions, including delivery of large commsats to geosynchronous orbit.

Modifications included liquid oxygen subcooled to −206.7 °C and RP-1 cooled to −7 °C for density (allowing more fuel and oxidizer to be stored in a given tank volume), several size and volume changes to the first- and second-stage propellant tanks, and several small mass-reduction efforts. The modified design gained an additional 1.2 meters of height, stretching to exactly 70 meters including payload fairing.

Two key improvements were the replacement of the first-stage engine with the full-thrust variant of the Merlin 1D and the replacement of the second-stage engine with the Merlin Vacuum (1D). The new first-stage engine featured an increased thrust-to-weight ratio while the new second-stage engine was optimized for higher performance in vacuum through modifications such as a larger exhaust nozzle and improved attitude control system. First stage booster can reach low Earth orbit as a single-stage-to-orbit if it is not carrying the upper stage and a heavy satellite



In late 2012, Elon Musk tweeted an image of the Merlin 1D-Vac firing on the test stand and stated "Now test firing our most advanced engine, the Merlin 1D-Vac, at 80 tons of thrust." Currently the official SpaceX's Falcon 9 product page lists the thrust of the Merlin Vacuum on the second stage of the launcher at 934 kN (210,000 lbf) and specific impulse of 348 seconds in vacuum conditions. The increase is due to the greater expansion ratio afforded by operating in a vacuum, now 165:1 using an updated nozzle extension

House for Pottery Festival / Office for Environment Architecture

http://ift.tt/nNxAFF

This is a house and atelier for a pottery artist family, located along a traffic circle at a station in suburban Osaka. The site is narrow flag-shaped (a rectangular site with a pole-like narrow path), with 3m of frontage and depth of 34m. There is a large apartment building on the south side, and idle lands on the north and east sides. A distant view of the beautiful mountain range of Mt. Nijo can be seen in the east direction.

USA, Russia and China among early entrants in race for Super Soldiers and Artificial Intelligence.

http://ift.tt/hZ0OVi
The USA has been researching ways to enhance the biology and performance of soldiers for decades.

Deputy Defense Secretary Bob Work warned that America would soon lose its military competitive advantage if it does not pursue technologies such as employing artificial intelligence.

Altering human beings from the inside to more effectively fight in combat is claimed to presents ethical dilemmas for American scientists and military planners.

Work says those ethical concerns typically don't apply to authoritarian governments like Russia's or China's, but their lack of hesitation in developing EHOs may force America's hand.

Previous US human augmentation research

DARPA had started work on a super-soldier suit called TALOS (Tactical Assault Light Operator Suit) unlike anything in the history of warfare. Engineered with full-body ballistics protection; integrated heating and cooling systems; embedded sensors, antennas, and computers; 3D audio (to indicate where a fellow warfighter is by the sound of his voice); optics for vision in various light conditions; life-saving oxygen and hemorrhage controls; and more, TALOS is strikingly close to the futuristic exoskeleton that Gorman first envisioned for DARPA 25 years ago, and aims to be “fully functional” by 2018.



It was the collapse of the Soviet Union that accelerated many of DARPA’s most radical super-soldier science programs. The revelation that the Soviets had developed an extensive biological-weapons program caused DARPA to bring biologists into its ranks, and with the life sciences at the fore, DARPA began to look inside the human body, toward a scientific capability that could transform soldiers from the inside out.

DARPA's Defense Sciences Office (DSO) investigated a mind-altering pain vaccine. Once injected into a soldier who had been shot, the vaccine would theoretically reduce the pain from inflammation and swelling. After 30 seconds of agony, the soldier would feel no pain for 30 days. As long as the bleeding was contained the soldier could keep fighting.

The government's research into halting the bleeding yielded another program that involved injecting millions of microscopic magnets into a person, which could later be brought together into a single area to stop bleeding with the wave of a wand.

DARPA has also studied whales and dolphins—mammals that don't need to sleep in long chunks like humans do—as inspiration for creating a soldier who requires little to no sleep for a week or more. Whales and dolphins independently control the left and right lobes of their brains, keeping one alert while the other sleeps. It's not known if DAPRA scientists made any progress with human lobe control, but they did explore powerful anti-sleep drugs like Modafini

DARPA Closer to Full-Scale Demonstration of Unmanned VTOL Aircraft Designed for Small Ships

http://ift.tt/hZ0OVi
Small-deck ships such as destroyers and frigates could greatly increase their effectiveness if they had their own unmanned air systems (UASs) to provide intelligence, surveillance and reconnaissance (ISR) and other capabilities at long range around the clock. Current state-of-the-art UASs, however, lack the ability to take off and land from confined spaces in rough seas and achieve efficient long-duration flight. Tern, a joint program between DARPA and the U.S. Navy’s Office of Naval Research (ONR), seeks to provide these and other previously unattainable capabilities. As part of Tern’s ongoing progress toward that goal, DARPA has awarded Phase 3 of Tern to a team led by the Northrop Grumman Corporation.

The first two phases of Tern successfully focused on preliminary design and risk reduction. In Phase 3, DARPA plans to build a full-scale demonstrator system of a medium-altitude, long-endurance UAS designed to use forward-deployed small ships as mobile launch and recovery sites. Initial ground-based testing, if successful, would lead to an at-sea demonstration of takeoff, transition to and from horizontal flight, and landing—all from a test platform with a deck size similar to that of a destroyer or other small surface-combat vessel.

http://ift.tt/nNxAFF

"All we need now are a new generation of Martian architects to design buildings made of Martian concrete that will be suitable structures for humans to live and work in," concludes the MIT Technology Review in their report on a new type of concrete designed for use on Mars.
