" Fulfils aeronautical dream first envisioned by da Vinci
On July 31st and August 2nd, 2010 the Snowbird succeeded in completing several sustained flights!! On the longest flight the altitude and airspeed were maintained for 19.3 seconds, setting a world first, and achieving the age-old aeronautical dream of self-powered flapping wing flight! The accomplishment of our goal is a success shared by all, and I must thank everyone who was involved for their help, sponsorship, advice, or simply for their interest in our project, which has motivated us when times where hard.
Please check out the media section of our website for pictures and video.
So what’s next?
As much as we would love to keep flying the aircraft, the failure of the drive line on the last flight of the day on August 2nd reminded us of the reality of the project. Fortunately the line broke in such a way that the wings were spared, but there are many parts where we have seen fatigue wear, and the risk of destroying a historical artifact is not worth the reward. Additionally, the pilot's training cycle, tapering period and weight loss phase (18 lbs in 4 weeks) were very specifically timed for the flight, and any further flights this season would be unlikely to result in longer records.

" Sikorsky Innovations, the technology development organization of Sikorsky Aircraft, today officially introduced “Project Firefly,” an all-electric helicopter technology demonstrator, at the Experimental Aircraft Association (EAA) AirVenture exhibition. Sikorsky Aircraft is a subsidiary of United Technologies Corp. (NYSE:UTX).
The Firefly Technology Demonstration Aircraft at EAA is part of the world symposium on electric aircraft. The demonstrator is one of the main attractions in the Aviation Learning Center along with other state-of-the-art commercially available and prototype electric aircraft.
In building the demonstrator, the Innovations team replaced the legacy propulsion system of an S-300CTM helicopter with a high-efficiency, electric motor and digital controller from U.S. Hybrid, coupled with a lithium ion energy storage system from Gaia. Integrated sensors provide real-time aircraft health information to the pilot through a panel integrated interactive LCD monitor. Eagle Aviation Technologies, LLC, executed the custom airframe modifications and assembly of the demonstrator aircraft.
The demonstrator will feature a 190-horsepower electric motor, a motor controller, a battery system, and cockpit controls. First flight is anticipated later this year, upon completion of ground tests and safety of flight reviews in accordance with Sikorsky standard practice for all aircraft programs.
Features of the “Firefly” include:
・ All-electric drive system
・Safe and efficient high-density energy storage system
・Automated monitoring and alert technologies
・Next generation cockpit displays
2012年に世界一周を目指すソーラーインパルス Solar Impulseは、4月7日に試作機（Solar Impulse HB-SIA）によるテスト飛行をスイスのPayerneで行い、約１時間半のテスト飛行を成功させました。テスト機は、2012年で使われる実機とほぼ同じ大きさでカーボンファイバーの機体の重さは約1.6tで、全長21.85m、翼長63.4m。両翼に取り付けられた12000枚の太陽電池とモーターなどのセッティングも確認されたようです。周到な準備期間を経て発表された、地道なプロジェクトの進行と今回の成功を一ファンとしてともに喜びたいと素直に思います。
" This morning at 10:27, the Solar Impulse HB-SIA took off from Payerne (VD) airfield on its maiden flight.
Under the eyes of thousands of spectators from all over Switzerland, Solar Impulse HB-SIA slowly climbed up to 1200 meters. The next 87 minutes Solar Impulse test pilot Markus Scherdel spent familiarizing himself with the prototype’s flight behaviour and performing the initial flight exercises before making the first landing on the Vaudois tarmac. The execution of these various manoeuvres (turns, simulating the approach phase) was designed to get a feel for the aircraft and verify its controllability.
“This first flight was for me a very intense moment!” exclaimed Solar Impulse test pilot Markus Scherdel, still under the emotion of the event, on stepping down from the aircraft. “The HB-SIA behaved just as the flight simulator told us! Despite its immense size and feather weight, the aircraft’s controllability matches our expectations!”
“This first mission was the most risky phase of the entire project. 1h27 of intense emotion after 7 years of research, testing and perseverance. Never has an airplane as large and light ever flown before! The aim was to verify the prototype’s behaviour in flight and to test its reaction to various manoeuvres. The success of this first flight allows us to envisage the further program with greater serenity!” said a delighted Andre Borschberg, CEO and co-founder of the project.
“We still have a long way to go until the night flights and an even longer way before flying round the world, but today, thanks to the extraordinary work of an entire team, an essential step towards achieving our vision has been taken”, adds Solar Impulse Chairman and initiator Bertrand Piccard. “Our future depends on our ability to convert rapidly to the use of renewable energies. Solar Impulse is intended to demonstrate what can be done already today by using these energies and applying new technologies that can save natural resources.”

" Visionary concept work for Samsung C&T explores the future of travel and transport.
Leading design and innovation company Seymourpowell is today unveiling full details of its visionary transportation concept, Aircruise - a giant, vertical airship powered by natural energy and designed to carry travellers in style and luxury.
Originally a self-generated project, Seymourpowell's Aircruise is the concept design for a hotel in the sky, with low passenger numbers and huge internal spaces offering room for living, dining and relaxing, as well as scope for dramatic and inspirational public spaces. The initial design proposes a bar/lounge zone, four duplex apartments, a penthouse and five smaller apartments.
The concept subsequently captured the imagination of Korean giant Samsung Construction and Trading (C&T). Driven by its interest in new materials for building, Samsung C&T appointed Seymourpowell to refine the idea and produce a detailed computer animation of the proposed experience to illustrate this visionary approach to the future. The video can be viewed here:
Lifted by hydrogen and powered by solar energy, the Aircruise concept also has obvious environmental benefits. Seung Min Kim, design director at Samsung C&T commented, "This was a dream concept project for us, helping to realise a future of sustainable buildings combined with innovative and luxury lifestyle. In an age when environmental impact is a key consideration for architecture, we are keen to extend this vision of the future by searching for solutions that can be realised by 2015 - the year that many futurologists foresee as the turning point for the future."
Although only a conceptual proposal, the transportation design team at Seymourpowell developed a detailed and achievable technical specification for the craft. See below for further technical details.
Proposed conceptual specifications for Aircruise as follows:
From the docking rig at the base to the tip, the ship is 265 metres tall. Hydrogen, the lightest gas, is used as the lifting gas, and is capable of lifting around 1.2Kg per cubic metre of volume. Large PEM hydrogen fuel cells will provide on board power and some drinking water.
The volume of the main envelope in the ship is calculated at 330,000 cubic metres, which equals 396,000 Kg of available lift at sea level (1,000Kg = 1 Tonne (t)).
Primary structure, envelope and systems 270t (reference - around the same weight as an airbus A380 super jumbo, empty weight)
People (estimate max 100 people on board) 15t
Total load factor 378t
Available lift excess is therefore 18-20t or 20,000kg of lift.
