Hot Air Balloon PNG

Airplanes are not the first vehicles to fly. We all know this today. Based on the idea that an object must be lighter than air in order to rise into the air and that hot air is lighter than cold air, the French Etienne and Joseph Montogolfier Brothers found the balloon. The Montgolfier Brothers filled a silk balloon with hot air, then when they released it, they saw the balloon rise. They did many experiments on this. On June 5, 1783, they succeeded in flying the first hot air balloon. This balloon was the first vehicle to be flown by man and had traveled 2.5 km.

Balloons are not easy to steer. For this reason, they left their place in the history of aviation over time to airplanes.

The operation of hot air balloons is based on a very simple principle: When hot air heats up, it rises. Today's balloons are designed according to this simple principle. The part that forms the main body of the balloon and is made of fireproof fabrics is filled with hot air. Under the main body of the balloon, there is a basket containing the passengers and the fuel to heat the air. The air in the balloon can be controlled through a hole at the top of the fuselage called the parachute valve. The balloon rises and falls with the help of the igniter part of the mechanism that heats the air above the passenger basket and the ropes that open and close the hole. When the balloon is wanted to rise, the rope that activates the igniter is pulled and the fire heats the air in the body of the balloon, causing it to rise. If the balloon is wanted to descend, the hole is opened with the help of the rope that controls the hole at the top and the hot air is allowed to fly away from the top of the balloon. As the air in its body cools, the balloon begins to descend again. If the balloon can only move up and down, you might ask, how does a balloon move? The answer to this question is hidden in the wind. The thing that drives the balloon is the wind. Winds blow in different directions at different altitudes of the atmosphere. The person who directs the balloon tries to catch a wind blowing in the direction he wants to go by descending or rising. Even very skilled balloon pilots cannot fully control hot air balloons. Sometimes the winds can blow from an undesirable direction. For this reason, it is usually safer for someone on the crew to follow the balloon from the ground in a car and check where it lands. In addition, it is necessary to check the weather conditions before the flight, determine the direction of the winds and measure the blow speeds.
