Civil Aviation

When talking about civil aviation, we are discussing the part of aircraft dealing with civilian life.  The part that deals with the military is another category all together.  Though the basics of the two are the same, their goals are different.  The civil aviation department has to do with transporting both people and goods and with safety.  The military aspect of it is engaging in warfare and delivering supplies. A lot of these aircraft include weapons on board for combat as well.

Many times, those who have flown aircraft in the military will fly in the civilian sector after their military duty is over. They may have taken retirement from the military or just made the decision to not re-enlist.  Despite the reason, they are usually very likely to be very passionate about the different areas of aviation and want to continue in it past the military.

Of course it takes more than just pilots in order for civil aviation to be able to operate smoothly.  There are hundreds of arrivals and departures of airplanes at airports all around the world each and every day.  There are many people that are in place that help to make certain the planes are safe, that they operate as they should, are fueled, and that they take off and land in the correct locations.

Anyone interested in any of the different areas of civil aviation only need to look as far as their local technical school for programs offered.  This will help them to train and fulfill the requirements needed to enter the field of civil aviation.  They need to be aware, though, of the security that surrounds the field of study, thanks to the hijacking of the airplanes on 9/11 that were used to attack our country.

 

A Brief History of Flight

The Wright brothers revolutionized the world through the invention of flight.  The concepts of distance and speed began to change with their invention.  Many things always seen as impossible began to suddenly seem possible.  Through experimentation, the perfect combinations of weight, strength, and carrying capacity was finally achieved.

airplaneWhen airplanes were first invented, they were called kites.  They had huge wings and not a lot of power. Just before World War I, aircraft that were more streamlined appeared.  They included increased horsepower and a better aerodynamic shape.  The wooden frames of the aircraft were replaced with welded steel tubing as well.  All of the assembly wings, tails, and fuselages were built using duraluminum then.

Over time, metal replaced all of the wood used in building the aircraft. The Boeing 247 was a revolutionary invention that streamlined the construction and included variable pitch propellers and retractable landing gear.  Every nation tries to use that best technology available in times of war, so with World War 2, jet fighters were developed.  During the 1980s, an all-composite design was introduced.  This design was used to make history as Brut Ratan flew non-stop without refueling around the world.  

Another form of aircraft to consider is the Voyager.  It had a lightweight composite airframe that helped it to circle the earth in only nine days. There are many other styles of mechanical flights that include helicopters, spacecraft, balloons, aeroplanes, and airships.  They all use a variety of methods to take off and to land, requiring specialists for each type of aircraft. 

There were many early pioneers that brought us to where we are today with flight. These include Charles Lindbergh, Amelia Earnhart, Abbas Firnas, Richard Pearse, Alberto Santos Dumont, Armen Firman, and, of course, the Wright Brothers.

When an aircraft is taking off, a taxiway is the typical way for it to take off and land within the airport.  After the aircraft gets up enough speed, it takes off into the air.  Full power usually has to be used for light flights.  When an aircraft is getting to the desired cruising altitude, they are considered to be “climbing”.  The descent of a flight is when the aircraft decreases their altitude to land. In both commercial and private flights, planning plays a huge part.  Without it, there are many things that may go wrong.

The Basics of Aviation

The term aviation as it refers to airplanes is a pretty complex term.  A lot of use take for granted the fact that so much of what we buy is transported to us through aircraft.  The idea that we are able to go thousands of miles in one days time by flying is a great convenience we don’t think much about.  It gives us the power to travel for business or pleasure all over the world.  Many moving companies also use aviation to transport personal goods from one home to another such as moversrochestermn.com, a local moving company that offers specialty moving services.

Jet Taking Off at TwilightAviation has played a huge role in the military as well.  They allow soldiers to get in and out of locations quickly, deliver supplies, and used to attack the enemy.  Of course, other countries use aircraft to do the same things against us.  Different aircraft are also used in rescues and to report the news through the media.  Many victims have had their lives saved thanks to the quick actions of those working on some of the different aircraft used in rescues.

There are a large number of jobs available within the field of aviation.  Only a small percentage of those working in the industry actually are able to fly aircraft.  The other workers are responsible for building and maintaining aircraft, and running the control towers to help avoid any accidents.  It takes a lot of training for the workers to become eligible to work in the field of aviation since there isn’t any room for errors to occur.

Over the years, the technology used in aviation has changed a lot.  The history of aviation is very interesting.  Those wanting to know more about the history of aircraft in our country can find a wealth of information online.  There are even time lines that are very detailed that can take the reader from the very beginnings of aircraft to the modern day versions.

There are aircraft museums around the world, as well, where you can view the history of aircraft.  Most of these museums include a variety of basic aircraft, war planes, and, in some cases, even homemade planes.  It can be very interesting to see the different kinds of planes and artifacts in these museums.  You won’t regret spending your time in this way.  In order to find a museum to visit, look online.  You may even find that their is one in your own neighborhood.

 

A Look at Radio Controlled Airplanes

A lot of RC airplane enthusiasts have a dream of seeing the full size replica of their favorite plane flying.  However, it isn’t easy to copy the precise dimensions of the full size version and make it into what you want. Even if you know how to use CAD software to draw and design the airplane, in order to make it stable, you have to also know the aerodynamic principles. That is always the first step for flying any model airplane. Before ever attempting to build and fly your very own model, you need to have your skill set up to at least intermediate. You will need to then chose a trainer full scale type of airplane.

The trainer airplane has built in stability in the design.  The wings are rectangular and have a constant chord. The wings are also located above the fuselage, helping it to have pendulum stability.  Generally, the landing gear is also a tricycle type.  This does not mean that the stability will be the same when the airplane is scaled down, though.  Those sort of airplanes do not fly well at all when you copy the same dimensions on your scaled down model. Like stated before, the aerodynamic designed has to be considered. This is known at the “Scale Effect” on the plane.  You are not able to scale down the viscosity of the air of the air molecules. This will create a different behavior. Many factors, such as the wing are and location, the location of the horizontal and vertical stabilizer, and the design of the airfoil all play a huge role on the stability of the airplane.

scale-rc-airplanes12It is essential to completely redesign the airplane. In order to achieve stability on the miniature dimensions, you have to redesign it based on the Reynolds number as well as the lift and drag coefficients. This is the reason that many of the kits have specifications that are for 30% to 40%.  This number is the percentage copied from the original, full sized airplane. Many times, things like the stabilizer was changed on the model. Other times, it is the wing are or the airfoil type to help with the stability.  The larger the model, the easier it is to copy the behavior and the exact dimensions of the full size airplane.  Because of this, 1/4 scale model airplanes tend to be quite popular with people that are serious about their RC airplane models.  Unfortunately, because of the cost and set up and the inherent dangers of the larger plane, only those with a lot of money can have these.  They require a large field to fly in and a lot of fuel.  They are only for the most serious RC airplane collectors.

 

Aviation Museums

By going to an aviation museum, we are able to take a journey into the past to see the aircraft that were used back then. The museums will generally include military, commercial, and private airplanes in their collections.  As with all other forms of transportation, aviation has seen a lot of change over the years.  By visiting an aviation museum, you are sure to have a deeper appreciation for where they have come.

dsc_8131-1024x768Some of the museums are well known while others are not.  This is mostly because of the type of aircraft on display. The Planes of Fame Air Museum is in Chino, California.  This museum has over 150 aircraft from different times in the military.  They sponsor air shows that draw in large crowds throughout the summer.

In Birmingham, Alabama is The Southern Museum.  This is a wonderful aviation museum to explore, especially if you enjoy learning about women in aviation and their role in flight. There are a lot of displays about women aviators and how they helped the early success of aviation. It’s a great way to show young girls how women can make an impact in society, even in areas dominated by men.

There are quite a few aviation museums all over the world to explore. You can easily find them by searching online.  You may even be surprised to find one near you.  If you are traveling soon, you could possibly squeeze in a couple of hours at a local aviation museum.  They are both educational and fun!

Non profit organizations own and operate most aviation museums. There is typically a small charge for entrance but that money is needed to help pay to keep the museums open.  Some of the museums are able to generate decent money to stay open due to the large volumes of visitors they receive every year.

For the most part, the aircraft at the aviation museums have been donated to them instead of purchased.  They are put in the museums as a way to honor the aviation field while on display.  They can also serve to remind visitors of what can be done by creative minds and a little ingenuity.  The advances we see today in aviation would not be possible without those who took a chance in the past.
