1. half the acceleration and the maximum speed, if the movements are also divided (if the pressure is equal)

2. I agree that the pressure is equal to the output. That is, that the movements have... homothetic parabolas.

Who does not know The Little Prince, the second most sought after book in the world – after the Bible – with more than 134 million copies sold in the world since 1943? Its creator, Antoine de Saint-Exupéry (1900 – 1944), was a french writer brilliant, author of several successful books that are now part of the French and international heritage.

Aviator by profession, first for the Post Office and later for the French Army during the During the Second World War, Saint-Exupéry's hours of piloting inspired much of his work. They also stimulated his interest in technical and scientific matters, a lesser-known aspect of his personality.

So, learning from his flying experience, he constantly sought to improve his planes and scribbled calculations and drawings in the margins of his manuscripts or on paper towels. Antoine de Saint-Exupéry criticized scientific rigor and praised the practical experience of men who risked their lives to go beyond the theories of engineers. Thus, from 1934 to 1941, he invented and patented 11 techniques in France and the United States; none of these patents made him money, but some of his ideas were applied to American aircraft.

Autograph documents of Antoine de Saint-Exupéry, who mysteriously died aged just 44, have been in demand and in increasing value for over fifty years, as a result of the incredible worldwide success of the Little Prince. The self-portrait is particularly interesting here.
