Boeing Flies First Manned Hydrogen Plane

boeing hydrogen fuel cell planeOver the last couple of months, a test pilot has taken Boeing's hydrogen fuel cell prototype up up and buy cialis 50 mg away! low altitudes and low speeds. Hydrogen fuel cells produce electricity and electricity, unfortunately, isn't very good at powering planes. So far, it's been difficult to produce enough power in such a small, light space.

In fact, the fuel cell airplane actually needed assistance from a lithium ion battery pack to take off. Once in the air, however, the power came entirely from the much more energy-dense compressed hydrogen.

Unfortunately, it doesn't look like hydrogen is going to solve our problems with consumer air travel. Boeing is hoping that the technology could find a home in unmanned or light-weight aircraft. Keep reading for Boeing's full press release.

MADRID, Spain, April 03, 2008 -- Boeing [NYSE: BA] announced today that it has, for the first time in aviation history, flown a manned airplane powered by hydrogen fuel cells.

The recent milestone is the work of an engineering team at Boeing Research & Technology Europe (BR&TE) in Madrid, with assistance from industry partners in Austria, France, Germany, Spain, the United Kingdom and the United States.

"Boeing is actively working to develop new technologies for environmentally progressive aerospace products," said Francisco Escarti, BR&TE's managing director. "We are proud of generic online viagra our pioneering work during the past five years on what better viagra or cialis the Fuel Cell Demonstrator Airplane project. It is a tangible example of how we are exploring future leaps in environmental performance, as well as a credit to the talents and innovative spirit of our team."

A fuel cell is an electrochemical device that converts hydrogen directly into electricity and heat with none of the best price on viagra products of combustion such as carbon dioxide. Other than heat, water is pill price propecia its only exhaust.

A two-seat Dimona motor-glider with a 16.3 meter (53.5 foot) wingspan was used as the airframe. Built by Diamond Aircraft Industries of Austria, it was modified by BR&TE to include a Proton Exchange Membrane (PEM) fuel cell/lithium-ion battery hybrid system to power an electric motor coupled to a conventional propeller.

Three test flights took place in February and March at the airfield in Ocaña, south of Madrid, operated by the Spanish company SENASA.

During the flights, the pilot of cialis delivered overnight the experimental airplane climbed to an altitude of 1,000 meters (3,300 feet) above sea level using a combination of battery power and power generated by hydrogen fuel cells. Then, after reaching the cruise altitude and buy tramadol in lakeland disconnecting the batteries, the pilot flew straight and level at a cruising speed of 100 kilometers per hour (62 miles per hour) for approximately 20 minutes on power solely generated by the fuel cells.

According to Boeing researchers, PEM fuel cell technology potentially could power small manned and unmanned air vehicles. Over the longer term, solid oxide fuel cells could be applied to secondary power-generating systems, such as auxiliary power units for large commercial airplanes. Boeing does not envision that fuel cells will ever provide primary power for large passenger airplanes, but the company will continue to investigate their potential, as well as other sustainable alternative fuel and energy sources that improve environmental performance.

BR&TE, part of the Boeing Phantom Works advanced R&D unit, has worked closely with Boeing Commercial Airplanes and a network of partners since 2003 to design, assemble and fly the experimental craft.

The group of companies, universities and institutions participating in this project includes:

I remember hearing talk about battery/fuel cell weight making hydrogen air travel way too difficult. While a small step, I think this is something that could be viably introduced to commercial flight as a 2nd power option; just because something won't work in theory, doesn't mean it won't work in practice :)
Hydrogen plane too heavy? Only because t

It seems to me that you might be able to solve the liftoff problem by using some of buy levitra online canadian phamacy the hydrogen in uncompressed form so that your airship starts off lighter than air, but then, as the hydrogen is used, it shifts into a more conventional plane for speed while in flight.
Why Fuel Cell in this Application

Why not just use hydrogen to power ICE? That should solve a lot of the weight issue and where can i purchase cialis provide more power as your not converting from electrical to mechanical.

This is just wanking. Years ago folks made a steam powered airplane which flew just like this thing. Not much difference really, both Hydrogen and steam are go nowhere technologies for aviation.
