Locusts give up aerodynamic secrets of insect flight
By Karen Sprey
19:04 September 20, 2009 PDT
It seems that locusts, the bane of farmers the world over, have served some purpose after all. With the aid of a wind tunnel and a high-speed digital video camera, scientists have captured the changes in the shape of the locust's wings during flight and created, for the first time, a computer model that recreates the airflow and thrust generated by their complex flapping movement. Modeling the aerodynamic secrets brings us a step closer to creating miniature robot flyers with the maneuverability and energy efficiency of an insect - such micro-aircraft would likely have huge benefits for search and rescue, military activities and inspecting hazardous environments.

Keeping supersonic transport quiet
By Paul Lester
20:54 August 4, 2009 PDT
Supersonic business jets have traditionally got a bad rap when it comes to practicality and the environment, with high costs, loud noises and short range far outweighing the benefits of speed. The future of air travel will therefore be subject to stringent criteria to ensure that economy and eco-credentials, particularly noise pollution, don’t take a back seat to comfort and performance, and with this in mind Supersonic Aerospace International seem to have hit a luxury-class balance between the two.

GE and NASA to give open-rotor jet engine systems a spin
By Jude Garvey
06:31 June 15, 2009 PDT
GE Aviation and NASA will run a wind tunnel test program over the northern summer to evaluate and test counter-rotating fan-blade systems for open-rotor jet engine designs. The newly improved rig for testing was originally used by GE and NASA in the 1980s on scale models of counter-rotating fan systems, which led to the development of the GE36 engine. The test program also demonstrated that an open-rotor jet engine consumed 30 percent less fuel compared to similar-sized conventional jet engines. Just think what a 30 percent drop in fuel consumption would deliver today, not only to an airline industry struggling to keep ticket prices down, but also the positive benefits to the environment.

The Mosquito single seater lightweight helicopter
By Paul Evans
17:33 May 12, 2009 PDT
The "Muecke" (mosquito) is a single seater lightweight sport helicopter concept that combines low weight and corresponding low flying costs in an easily transportable design which would make this flying machine the ultimate in personal aviation. The mini chopper is intended to be powered by a shaft driven turbine and features counter rotating blades. This means it does not require a tail rotor, instead utilizing movable paddles at the tip of the rotor blades which act like a kind of thrust vectoring of the turbine exhaust to help make course corrections in forward flight as well as in hover.

Entecho's Hoverpod: the 3-seat, skirt-steered, 75mph VTOL flying saucer
By Loz Blain
07:35 May 4, 2009 PDT
We continue to be optimistic about the future of personal flight - and from flying cars to coaxial flying platforms, ion-powered jetpacks and more recreational solutions, plenty of innovative designs are striving for viability. We haven't seen anything like this one before though - Entecho has come up with an operating prototype of a sort of cylindrical fan-forced flying saucer, steered by directing the downward airflow through a flexible skirt that allows easy directional control. The blades are not exposed and move reasonably slowly, it's stable in flight and the system is remarkably simple from a mechanical point of view. It's also quite simple to fly using a joystick controller. Totally VTOL and with a small footprint, perhaps the Entecho Hoverpod might deliver as a practical and affordable personal flight solution.
