Solar Impulse
- The document describes Solar Impulse 2 (HB-SIB), the third and final solar-powered aircraft model created by Bertrand Piccard, a team of 50 engineers, and 80 technological partners over 12 years with a budget of 140 million Swiss Francs. - The first prototype, HB-SIA, had a problem with its wing spar in 2012, requiring an additional year of development. HB-SIB incorporated lessons learned and has an increased payload, isolated electrical systems, and improved reliability. - Solar Impulse's goal is to attempt the first round-the-world solar-powered flight in 2015 without using any fuel, which would rise to unprecedented technical, human and operational challenges

- 10. Problem on thespar In the summer of 2012, during the final structural test of the wing spar, a problem was encountered and the spar broke. After the initial shock, the team got together, analyzed the problem and concluded that an additional year was gained for new Solar Impulse adventures.
- 11. The construction ofSolar Impulse 2 or HB-SIB started in 2011, incorporated much lessons learned from the previous HB-SIA, but with more spacious cockpit enabling the pilot to fully recline during flights of 4-6 day duration. It will have an increased payload, isolated electrical circuitry to enable flights in rain, and improved reliability through system redundancy.
