Odysseus: Aurora's radical, unlimited endurance, solar powered aircraft
May 2, 2008 Aurora Flight Sciences has revealed the design of the aircraft it hopes will achieve the ambitious goals set out in DARPA's ambitious Vulture program: sustained uninterrupted flight for over five years at altitudes of 60,000-90,000 feet. Known as Odysseus, the solar-powered concept aircraft is as radical as the mission it is designed to accomplish, combining three self-sufficient “constituent aircraft” in a unique Z wing configuration that spans almost 500 feet (150 meters). The modular design provides several advantages - the shape of the aircraft can be adjusted to maximize the solar collection properties during the day and spread flat for aerodynamic efficiency at night-time, and because each of the constituent vehicles is capable of autonomously docking at altitude, the design also facilitates the replacement of one section of the plane whilst it is still aloft.

Aeroscraft ML866 Milestone
April 8, 2008 A spectacular new type of aircraft is one step closer to take-off with the announcement that the United States Federal Aviation Administration (FAA) has accepted the type certification application for the Aeroscraft model Aeros ML866. (read more...)
AeroVironment awarded patents for wind-power system
April 14, 2008 A name familiar to Gizmag readers through its achievements in the field of Unmanned Aircraft Systems, AeroVironment is also a developer of efficient electric energy systems, an area in which it has been awarded a series of patents relating to its "Architectural Wind® Building-Integrated Energy Generation System" - a system which takes a new approach to harnessing wind power using low-profile turbines designed to maximize electricity generation by taking advantage of the way wind flows over certain types of buildings.

Bumpy whale fins set to spark a revolution in aerodynamics
March 21, 2008 It seems despite man's endless ingenuity and the incredible modeling power available to inventors through CAD systems, we keep looking to nature to find ever more effective ways of doing things. Millions of years of evolution's trial and error approach have resulted in some incredibly effective designs that are ready to be incorporated into human constructions if we can only identify, understand and replicate them. The random-looking bumps on the humpback whale's flippers have just inspired a breakthrough in aerodynamic design that seems likely to dramatically increase the efficiency and performance of wind turbines, fans, flippers and even wings and airfoils. WhalePower's tubercle technology seems like nothing less than a revolution in fluid dynamics. (read more...)
Boeing KC-767 refuels an F-15E in night conditions
January 31, 2008 The Boeing KC-767 tanker aircraft has successfully transferred fuel to an F-15E at night – a world first manoeuvre for that model. Transferring fuel through a boom, via the remote vision system, and during night-time conditions, will significantly reduce risk for future tanker customers like the U.S. Air Force. (read more...)
Aptera officially launches futuristic, super-efficient three wheeler
The pressing need for a shift to efficient, low-emission vehicles has seen an array of eco-friendly models showcased by major auto manufacturers in recent times, but this new era of personal transportation also provides a starting point for smaller players with fresh ideas to enter the marketplace. Fitting squarely into this category is Aptera Motors, a Californian based company that has just announced the official launch of the Typ-1 - a radical new three-wheel, two-seat design available in all-electric or plug-in-hybrid versions that bundles bleeding-edge aerodynamics, incredible fuel efficiency and a strong focus on safety in a package that will cost less than USD$30,000. Gizmag spoke to Aptera Co-Founder & CEO Steve Fambro on the technology behind these eye-catching vehicles and the future plans for the company as it moves rapidly into the commercialization phase.

Logan Renault eco² achieves emissions of 71g/km
The Logan Renault eco² Concept has achieved emissions of 71g/km while traveling a distance of 172.2km on just 4.69 litres of biodiesel at the 2007 Challenge Bibendum in Shanghai – an event created by Michelin in 1998 that promotes sustainable transport and the development of fuel-efficient, clean automotive technology. In NEDC combined cycle homologation tests for the eco² it achieved a result of 97g CO2/km and finished second out of 74 vehicles in a combined criteria test involving an acceleration test, a slalom test, noise emissions and a regularity run. To put the emissions results in perspective, a compact diesel achieves around 130g CO2/km and the exceptionally green smart fortwo diesel comes in at 88 grams of CO2 per kilometer. (read more...)
America’s only 180mph rolling-road wind tunnel
October 1, 2007 The Windshear rolling-road wind tunnel in North Carolina will be one of the fastest and most advanced facilities in the world, and the only in America capable of 180mph (around 300kph) testing. The US$40 million complex will be an excellent resource for Formula One, NASCAR and most other racing teams – but interestingly, street-legal supercars like the Bugatti Veyron at the forefront of high-speed aerodynamic design still have nowhere to test their 250+mph models.
