Glider defines a special type of aircraft which does not have an engine. Most of the gliders resemble airplanes and have small auxiliary propulsion plant but have no means of propulsion at all in most cases. Currents the gliders have slender wings as well as streamline body. In addition, the unpowered varieties of gliders are launched by use of an electric shock cord, a cable that is attached to the front of the glider and to move, it is pulled by the launching crew. On the other hand, the powered gliders can take off or climb on their own. Gliders
History has it that Otto and Gustav Lilienthal from Germany were the first to make the first successful piloted glider flight in the year 1891. There are various types of gliders that include hang gliders, sailplanes, paper glider, paragliders, military glider, rocket gliders and unmanned gliders such as a paper airplane. Model gliders and flying bombs among others. This paper, therefore, seeks to discuss the disadvantages and the advantages of gliders as well as the for types of bad gliders.
Advantages of gliders
One main advantage of recreational gliders is that they are very easy to operate as well as fly. This is majorly for sporting activities where they are used. Also, at even the age of fourteen, one can solo the glider due to their ease of operation as opposed to the airplanes whereby one can’t solo until one is sixteen years old, meaning their operation and usage is easy.
Secondly, the gliders are less expensive as opposed to planes hence flying the gliders become affordable. It is reported that most gliders can start at thirty-five dollars per hour, this makes people who wish to fly the gliders spend low as compare those who wish to ride in aircraft or planes
Thirdly, during the flight in a glider, it enables a clear and easier to sight distant objects. Further one will be able to sight other gliders around hence avoiding a collision, sight, and analyses the cloud condition. The Hang gliding is also good for people with back, neck or shoulder problem. The lightweight of the gliders enables the fast movement.
In addition, the unpowered gliders encourage saving of energy. When the engines are used on the gliders, it will require the use of energy just like airplanes. Therefore, in the absence of engine one needs to find the orographic lift or thermals to keep the glider going in their air. If none of the above exist, then you will require enough energy to get back to the airport with the glider.
Finally, other advantages include, suitable for both children as well as older people. The materials to which the gliders are made of are easy to obtain in any place. Similarly, its presence in any environment does not contribute environmental degradation, unlike the planes that release various gases into the air hence contribute to air pollution as well as noise pollution.
Disadvantages of gliders
To begin with, one major disadvantage of the glider is that, they are very dangerous regarding long-lasting injuries. Since the gliders are easy to break as compared to planes, they cause severe injuries whenever accidents occur to the persons in the gliders.
Secondly, gliders are not viable and reliable, practical transportation alternative for passages due to the lack of enough power to maintain heavy luggage as opposed to aircraft with the energy to be used to carry people. In addition, its low speed and limited carrying capacity make the gliders not a sure means of transportation to passages. Finally, its design takes lots of time to bring it to completion to a point that it can be used.
Four types of gliders
This is a type of glider that is made out of paperboard or paper. The paper is systematically folded along well-defined lines. Its origin is connected with the ancient China as well as Japan. Before the advent of planes, the paper gliders were the common man-made heavier-than-air of which used the principles could be appreciated. The reason as to why the paper glider falls under the bad glider is that the glide ratios is very poor as compared to others like the motor gliders. The increase of owing loading on the paper glider can cause the breakdown of the laminar flow over the wings of those of glued and taped construction.
Walkinglong glider design
A walkinglong glider is also another category of the bad glider. It is a lightweight as well as slow flying aircraft that is designed to be kept in flight through a controllable slope soaring in a place of a rising air that will be generated by the pilot who will be walking along the glider holding the paddle. There are various types of walkinglong glider that include air surfer, tumblewing and follow foil among others. The reason as to why it falls under the bad glider is that it a type of glider that must fly across at or below the walking speed of the pilot. In most circumstance, lightweight materials, as well as the specific design, will always reduce the speed off the glider hence becoming a bad glider.
Paragliding glider also become a bad glider due to its working condition. The paragliders are lightweight as well as foot-launching aircraft having no rigid primary structure. The pilot holds the paragliders and is suspended below a fabric wing as the glider moves. Due to its nature, the paraglider makes it difficult to fly for a longer distance makes it fall under the bad gliders.
The last type of bad categories of gliders is the motor glider that is a winged aircraft that fly without engine power as well. The motor glider is capable of sustaining soaring without thrust that result from means of propulsion. There are other types of motor gliders include cross-over gliders, electric motor gliders, touring motor gliders. They motor gliders are majorly used for recreational activities. The motor gliders are better than paper and walkinglong glider due to higher speed. The many disadvantages that surround its usage, as well as operation, qualifies it to be under the bad gliders.
The glider that was made moved for 2.5 meters but after the correction, it was able to move up to four meters may be because the size of the wings as well as the shapes were improved so as to improve the laminar flow of air giving the glider a lift hence a longer flight distance. This means that when the wings are in bad shape, the glider will not fly for a longer distance.
