A hot air balloon refers to a kind of aircraft that consists of a bag and hot air. The bag is also referred to as the envelop and it is designed in a way that it can contain heated air. The bag is connected to a wicker basket or capsule beneath it for carrying passengers. When in need of hot air balloons Colorado is the best location to check out.
Traditionally, wicker baskets are included in models that fly low over short distances. However, the models whose designs allow them to go for long distances and attain high altitudes incorporate capsule. The air inside the balloon is usually heated using an open flame. The heated air inside the balloon make it buoyant as a result of reduced density.
It is impossible for the balloon to fly beyond the atmosphere like is the case with all kinds of aircraft. It is not necessary to seal the bottom of the envelop like it is done in gas balloons. The reason why the bottom is not sealed is because the gas at the bottom of the bag usually has the same atmospheric pressure as the air outside the balloon.
When the balloon is designed to carry people, it is made of a single-layer, fabric gas bag. A mouth or a throat refers to the opening at the base of the envelop through which air is heated. Heating of air is achieved using burners placed in the basket and heating the air below the opening of the envelop. Various kinds of fuel can be used to heat the air, including propane and liquefied gas.
The envelop of the balloon is made from various materials such as Dacron and ripstop nylon. The manufacturing process involves cutting the material into panels and then sewing them together. The sewing of the panels together is done along with load tapes for holding the gondola in place. The panels are referred to as gore sections or gores, and they extend from the mouth of the envelop to the crown.
There is a lot of variance in the number of gores included in an envelope. The number can be as small as four or as big as twenty-four. The top of the envelop has a crown made of metal material. In most cases aluminum metal is used to make the ring. The ring has load tapes attached to it. The load tapes get sewn together to form a loop at the bottom for attaching the gondola.
Sewing of the panels together is done through a technique called French fell. Other names for this technique are French felled and double lap seam. French fell involves fabrics that make up the panels being folded over each other on the edges. The folding also incorporates the load takes. Zigzag and flat lap are also methods that may be used in the place of French felled.
To make the envelop air- and water-tight, a coat is applied over it. Silicone and polyurethane are the two most commonly used coats today. The effective life of the envelop is reduced or exhausted by the degradation and weakening of the coat applied on the envelop. Common causes of degradation of the coat include mechanical wear and tear, heat, and moisture.
