New VXX competition reveals changes for US presidential helicopter

viernes, 19 de febrero de 2010

The US Navy has launched the process to buy a new presidential helicopter, nine months after deciding to cancel the Lockheed Martin/AgustaWestland VH-71 despite spending $3.2 billion
Rather than buy a common aircraft to replace 11 Sikorsky VH-3Ds and eight Sikorsky VH-60s, the service would consider splitting the contract with a mixed fleet, the RFI says. Options under review include buying a common aircraft with two variants, or simply purchasing two different aircraft types.

Commercial Spaceflight Federation Welcomes Historic NASA Commitment

$75 Million Pledged For Commercial Suborbital Flights, Payloads
The Commercial Spaceflight Federation enthusiastically welcomed NASA's announcement Thursday that the agency will fund dozens of science and education payloads to fly on commercial suborbital vehicles built by companies including Armadillo Aerospace, Blue Origin, Masten Space Systems, Virgin Galactic, and XCOR Aerospace.  At the first annual Next-Generation Suborbital Researchers Conference, NASA Deputy Administrator Lori Garver announced in her keynote speech today that President Obama's Fiscal Year 2011 budget request for NASA commits $75 million in funding over five years for the new Commercial Reusable Suborbital Research program (CRuSR).


Bye Energy, Inc. Launches The Green Flight Project


DENVER,ColoradoFebruary18, 2010 – Bye Energy, Inc., an integrator of alternative energy and renewable fuel technologies for business and general aviation aircraft, is launching "The Green Flight Project" ( to enhance the development of an electric and electric-hybrid propulsion system (EHPS) forcommercial application. The objective of the project is to design and integrate an EHPS into a full-scale proof of concept airplane.

System architecture for Bye Energy's EHPS includes an electric motor and controller, lithium-ion battery and management system, electric energy management system, auxiliarypower unit, thin film photovoltaic cells, variable pitch propeller and proprietary energy capture devices exclusive to the company.

George Bye, CEO of Bye Energy, said that although all-electric propulsion systems and aircraft are being developed, they do not yet compare to the potential utility and performance of a hybrid design. "Intelligent power management technology, greater lithium-ion energy density and more efficient light-weight engines have now matured to the point where integration of these components becomes extremely compelling," he said. "We believe the general aviation market is at the same point the U.S. auto market was about a decade ago when the first affordable automotive hybrid alternatives became commercially available."

Charlie Johnson, COO of Bye Energy and former President of Cessna, said the time to accelerate incorporation of new hybrid technology has arrived. "General aviation is a vital market that will benefit from the environmentally friendly, lower cost,more efficient and higher-performing aircraft," he said.

Over the past year, Bye Energy has forged relationships with multiple technical partners including UQM Technologies, Inc. ( for the electric motor and controller, Vertical Power, Inc. ( for the energy management system, Porous Power Technologies, LLC (www.PorousPower.comfor the lithium-ion battery and separator technology, Scion Aviation, LLC ( for composite parts and materials, EEtrex Inc. ( for the battery system and Ascent Solar Technologies, Inc. ( for thin film photovoltaics.   

Bye Energy is accepting support from sponsors for The Green Flight Project. Early sponsors supporting the project launch include Wings over the Rockies Air & Space Museum and Colorado Capital Bank.
