Worked Solution & Example Answer:The first flight around the world without using fossil fuel, was completed in July 2016 by the Solar Impulse 2 - Leaving Cert Engineering - Question (m) - 2017
Step 1
Using improved motors and a large number of solar cells
Answer
Solar Impulse 2 was equipped with advanced motors that allowed it to generate sufficient power for flight. This was accomplished by utilizing a significant number of solar cells that harnessed solar energy. The solar cells charged the aircraft's batteries, enabling it to fly without relying on fossil fuels.
Step 2
Take off without assistance and circumnavigate the world
Answer
The aircraft took off independently and was able to navigate around the globe. The journey was meticulously planned and executed in stages, allowing the single pilot aboard to manage the flight efficiently. This innovative approach demonstrated the potential of renewable energy in aviation, setting a precedent for future environmentally friendly air travel.
