Hot Air Balloon ~ Montgolfier Brothers

Recommended Posts


Ephemeris June 4.

1783.- In Annonay, France, the Montgolfier brothers, Jacques Étienne and Joseph-Michel, make their first public demonstration that hot air weighs less for the same volume of cold air, and bagging is capable of raising a spherical linen bag lined with paper, 11 meters in diameter with a capacity of 800 m3 and a weight of about 226 kilograms. The flight covers a distance of about 2 km, with a duration of 10 minutes and reaches an estimated altitude of about 1,600 to 2,000 meters. The future of aerostatic navigation has begun. (237 years ago)

Joseph-Michel Montgolfier (26 August 1740 – 26 June 1810) and Jacques-Étienne Montgolfier (6 January 1745 – 2 August 1799) were the inventors of the Montgolfière-style hot air balloon, globe aérostatique. The brothers succeeded in launching the first manned ascent, carrying Étienne into the sky. Later, in December 1783, in recognition of their achievement, their father Pierre was elevated to the nobility and the hereditary appellation of de Montgolfier by King Louis XVI of France. The hot air balloon is the oldest successful human-carrying flight technology. It is part of a class of aircraft known as balloon aircraft. On November 21, 1783, in Paris, France, the first untethered manned flight was performed by Jean-François Pilâtre de Rozier and François Laurent d'Arlandes in a hot air balloon created on December 14, 1782, by the Montgolfier brothers. Hot air balloons that can be propelled through the air rather than just being pushed along by the wind are known as airships or, more specifically, thermal airships.
