SEMINAR ON

SOLAR IMPULSEHB-SIB

AN IDEA BORN IN SWITZERLAND

Switzerland is considered now the most innovative

country in the world

WHY SOLAR IMPLUSE IS SWISS?

The two creative spirits of the pilots are Swiss

Switzerland protects the environment and plays a

leading role internationally in that matter.

Many leading Swiss companies supports Solar

Impulse financially and many high-tech Swiss

companies have mobilized their expertise and

technical innovation to build the planes.

The four engines of solar Impulse are Swiss

WHY AN IDEA ABOUT SOLAR IMPULSE

(The purpose)

To fly around the world without fuel, this is the challenge Bertrand Piccard set himself following the first successful non stop round the world balloon flight in 1999 with Brian jones.

The challenge for Bertrand was therefore to design a manned solar airplane capable of flying day and night.

That is when the real adventure begin, immediately raising the host of questions

What shape will the plane have?

Will solar panels be sufficient?

How will it be able to fly at night?

Why solar energy?

Infinity

Availability

Inexpensive

No pollution

No preservation cost

High power-to-weight ratio

Feasibility study

In 2002 after discussing his project with

energy and aerospace specialists Bertrand

Piccard presented it to the Ecole

Polytechnique Federale de Leusanne

(EPFL). Together they launched a

feasibility study in 2003, managed by

Andre Borschberg, an engineer and former

Swiss air force pilot.

3rd and the Final Model

(HB-SIA)

SOLAR AIRCRAFT

Bertrand Piccard and

50 aeronautical engineers, physicists and technicians

80 technological partners

Main partners (Solvay, Omega, Schindler )

100 advisers

and

suppliers

Cruise speed: 70 kilometres per hour (43 mph)

Endurance: 36 hours (projected)

Service ceiling: 8,500 m (27,900 ft) with a maximum

altitude of 12,000 metres (39,000 ft)

Problem on the spar

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.

The construction of Solar 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.

2003: Feasibility study at

the École Polytechnique

Fédérale de Lausanne

2004–2005: Development of the

concept

2006: Simulation of long-haul

flights

2006–09: First prototype (HB-

SIA)

2009: First flight of prototype

2009–11: Manned test flights with

prototype

2011–12: Further test flights

through Europe and North

Africa in 7 legs

2011–13: Construction of

second prototype (HB-SIB)

2013: Continental flight

across United States(Mission

Across America)

2014: First flight of HB-SIB (2

June)

2015: Planned world tour in

several stages

The historic moment on 8 July 2010

resulted in, not one, not two, but three world

records for HB-SIA and its pilot! The prototype

aircraft was awarded records (in “Solar-Powered

Aeroplane” category) for “Gain of Height”

(8744m), “Duration” (26h 10min 19s) and

“Absolute Altitude” (9235m).

2015 will be the year Solar Impulse

has been working towards: the attempt of

the First Round-The-World Solar

Flight. Bertrand Piccard and André

Borschberg, the two Pilots and Founders,

fly around the world with no fuel, rising up to

technical, human and operational

challenges that have never been faced

before.
