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.
Traditional low-altitude, short-distance models of these products incorporate wicker baskets. However, models that are designed to go long distances and achieve high altitudes incorporate a capsule instead. An open flame is usually used to heat interior air inside the balloon. Heating air reduces its density in comparison to the surrounding air, which makes it buoyant.
These balloons are incapable of flying beyond the atmosphere just like all kinds of aircraft. As opposed to gas balloons, these balloons do not need to be sealed at the bottom. The reasoning behind this design is that the air near the bottom of the envelop has the same atmospheric pressure as the surrounding environment. This technology is the first-ever human-carrying flight technology in the world.
A single-layer, fabric gas bag is used to make balloons designed for carrying people. There is an opening at the bottom called mouth or throat. Burners are placed in the basket beneath the bag to warm the air within it. Fuels utilized in the burners include propane and liquefied gas.
Different kinds of material can be used to manufacture the envelop. Main examples are Dacron and ripstop. The material used for construction is cut to make panels that are then sewn together, forming the envelop. The gondola is held using load tapes that are also sewn into the panels too during production. Panels are also called gore sections simply gores, and they extend from the bottom all the way to the ring at the crown.
The number of gores in the envelop varies a lot, with some having only 4 panels while others having as many as 24 sections. There is usually a crown ring at the top of the envelop. The ring is usually made of aluminum in most cases, but other metals may also be used. Load tapes attach to the ring at the top. Load tapes are sewn into loops at the bottom to attach to the basket.
A method called French fell, double lap seam, or French felled is used for sewing panels of the envelop together. In this method, fabrics are folded over one another at their edges, with the load tape included and then sewn using two rows of paralleled stitching. Other methods that may also be used instead of French fell are zigzag and flat lap.
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.
