Downunder Posted July 9, 2015 Posted July 9, 2015 Pretty obvious from Pipistrels statement, siemens undermined their effort to appease airbus. Disgraceful really......
pylon500 Posted July 9, 2015 Posted July 9, 2015 Airbus wants the fame, not realising the channel has already been crossed by an electric plane 35 years ago; <https://en.wikipedia.org/wiki/Solar_Challenger> May not have been a production plane, but then I don't think the E-Fan is either? I think Pipistrel should have called Siemens bluff, after all, most of the production electronics will probably end up coming out of China anyway... 1
Birdseye Posted July 9, 2015 Posted July 9, 2015 I think Pipistrel should have called Siemens bluff, after all, most of the production electronics will probably end up coming out of China anyway... That would be one in the chops for Siemens, cheap Chinese labour versus cheap slave labour. Oops, its probably not polite to mention Siemens 1940s activities.
Guest asmol Posted July 9, 2015 Posted July 9, 2015 Look what i just found. https://gliderrider.today/take-that-siemens-and-airbus/ TAKE THAT, SIEMENS AND AIRBUS! Just a day after Siemens (acting as surrogate villains for Airbus) legally made it impossible for Pipistrel to make it’s planned flight in the electric-powered Alpha Trainer over the English Channel – a kind of historical aviation rite of passage that Airbus wanted to hog for itself tomorrow with its prototype E-Fan – all was righted again in the world of justice and fair play. A young Frenchman did what the French do best: got in the face of the corporate bullies and made the first electric crossing of the channel in history in his tiny Cri Cri. Corporate malfeasance is at least this time forestalled from pushing people around: we couldn’t be happier if Lindbergh had landed in Paris all over again. Here’s the information as Ivo Boscarol, head of Pipistrel, released it just moments ago. I can imagine (and read between the lines) his great satisfaction, nay, glee, that although he acceded to Siemen’s ridiculous demands to halt the planned Pipistrel flight over the Channel yesterday, someone other than Airbus gets the glory that will never be taken away. Today, I am proud to say, “Je suis francais!”, and echo the country’s time-honored motto: “Liberté, égalité, fraternité.” Today, a Frenchman showed us that justice sometimes comes with the little whir of tiny electric motors and gnat-sized wings. Take it away, Ivo: Dear All, It is my pleasure to inform you that our friend Hugues Duwal after reading the information that Pipistrel was blocked in flying across the English Channel today became the first electric aircraft to cross the English Channel in his CRI-CRI E-Cristaline Electric aircraft. https://sl.wikipedia.org/wiki/Colomban_Cri-cri https://www.youtube.com/watch?v=rkEHIv1o7u8. As Duwal already had the permanent permit to fly his aircraft there was no need to ask for a permit to fly over the English Channel, but only to fill the flight plan. It was possible to keep the flight information secret up to the end. From the available information that we have, shortly after the flight announcement, an order was issued to stop him but he did not respect it and he successfully crossed the channel this evening, 9. July 2015 in the first flight over the channel with electric powered aircraft in the history . HUGUES DUWAL is former world electric aircraft speed record holder:http://www.wired.com/2011/07/electric-airplane-pilot-breaks-own-speed-record/ Attached the photo after the successful flight. We congratulate Hughes for his achievement and wish him a great celebrationtomorrow! Ivo Boscarol
TezzaP Posted July 9, 2015 Posted July 9, 2015 Fantastic outcome and in a tiny Cri Cri as well. Cop that Airbus and Siemens. 1
kasper Posted July 10, 2015 Posted July 10, 2015 A prop should not be to hard to source.Electric variable pitch would be really great. Could also be used for regeneration as a form of airbrake. But how many horse does a Sapphire need for sustained flight? Depends on the sapphire ... - the light weight 95.10 with the fabric wings fly my fat old arse around on 20-ish HP at 50mph ... I have a whopping 28hp (at best) on takeoff - the heavy weight 95.25/95.55 with the glass wings have 40-46hp at takeoff and from my flight in the 447 I was cruising at around 5,000rpm which by the power graph is in the order of 30HP but was in the 65-70MPH region. Electric would work for either and I have on paper worked out how to convert the 95.10 to electric BUT the cost is very high AND the battery tech is not good enough. Maybe when the next rebuild comes up on the airframe it will be different and I will not keep the internal combustion 1

Happyflyer Posted July 10, 2015 Posted July 10, 2015 Lovely to see Airbus get beaten but it all pales in comparison with Solar Impulse which was just airborne for five days flying from Japan to Hawaii and was totally on batteries every night.
Geoff13 Posted July 10, 2015 Posted July 10, 2015 That is sticking one up the big boys. Pity Siemens could have had the glory as well as Pipistrel.
Litespeed Posted July 10, 2015 Posted July 10, 2015 Depends on the sapphire ...- the light weight 95.10 with the fabric wings fly my fat old **** around on 20-ish HP at 50mph ...

Maybe when the next rebuild comes up on the airframe it will be different and I will not keep the internal combustion The economics will change over time. A good future source of complete systems will be the latest electric motorbikes. 50hp a big battery and controller. As bikes get written off with barely a scratch- the whole bike might be under $2000 as a wreck. That would make a cheap package and is already a proven system 1
