 * Why are the benefits and drawbacks of experimentation in our society generally and in our lives more specifically?**


 * Experiments can benefit or endanger our lives in so many ways. The invention of medicine has helped our lives and also endangered many. Inventions in my opinion have a 50% chance to be successful or harmful. The way that the helicopter turned out was successful. This invention led to safety procedures and also led to financial aid for other countries. A successful experiment will let you be able to start your life with a good business. make the right experiment and you can be a billionaire. Some of the drawbacks of experimentation is not knowing whats to come. Whether whats to come is good or bad. An experiment can go bad in an instant giving a chance to cause harm to nearby people around you or harm to yourself.**


 * The helicopter was a brilliant experiment and is now used for a ton of useful things such as rescuing people, transportation when going long distances, crop dusting over farmers crops, taking snowboarders to mountains to ride down the mountains slopes, and etc. Experiments are important for the development of our economy. Look at our hospitals and how the doctors know what procedures to do and how to give surgery on a wounded person. All that started with one successful experiment that broke out to many more experiments. For our society experiments are a step forward in the future.f**


 * The helicopter is a well known aircraft all around the world but how did the idea come to life? **

The earliest references of vertical flight is dated around 400 B.C. in china. Little kids played with a toy made out of bamboo that was designed like a helicopter.The chinese helicopter toy was soon introduced to Europe. Artists during the time of the Renaissance drew and painted pictures of this toy.

 * During the 1500's artist Leonardo Da Vinci drew pictures of a flying aircraft that many people** **say inspired us to make the modern day helicopter.**

 * In 1784 Launoy and Bienvenue invented a toy that could lift up and move around with its rotary wing. The word helicopter was brought upon by a french writer named Ponton D'Amecourt. He put the words helico which means spiral, and pter which means wings together to make the word helicopter. in 1907 Paul Cornu invented the first piloted helicopter the only downfall was that the experiment was unsuccessful.**
 * [|Igor Sikorsky] is considered to be the "father" of helicopters but thats not because he invented the helicopter but because he is the first person to make a successful helicopter.**
 * Igor Sikorsky began working on helicopters during the year 1910. Igor built a successful VS-300.** ** Igor was also the person who made the first military helicopter, the xr-4. Since those timesmany of helicopters have been successfully made. **

Uses of helicopters today

**Helicopters are used every day in the U.S. for rescue missions. There is an actual organization called Otago Rescue Helicopter Trust. As soon as they get a call that someone is in danger they act within seconds and head to the scene. The group operates a helicopter named BK117 for their rugged encounters. Operating in dangerous weather conditions is no problem for the extreme condition modeled helicopter. It can take on almost any weather smoothly with little to no complications. It’s compact propellers allow it to land in small areas that no regular helicopter would be comfortable with. It also has plenty enough room for medical use in the rear of the helicopter. This organization is open 24/7 and very serious at what they do. **



**Modern day helicopters are also used by the Military for many reasons. The scout helicopter used to find and identify heavily armored enemy artillery for the safety of friendly allies. Then you have the attack helicopter which is heavily armored and is used for heavy warfare. It has laser guided missiles to mark where to fire and get a direct hit on the enemy. With these types of helicopters the death rate for U.S. soldiers decreased. ** **Medical helicopters are used every day for emergencies. Trauma patients are more likely to live by being air lifted rather than a ground ambulance. They are great for far distance severely injured patients. For example if a person is bitten by a highly venomous snake they most likely won’t make it to a hospital in time to be treated. By air transportation the patient has a much more likely chance of treatment resulting in survival. **

The first helicopters ever built were terrible the would only stay in the air for a certain number of hours. In fact the first helicopter crashed in 1946. Accidents were not uncommon for helicopters back then. The highest air time for helicopters was 275 hours. Helicopters started to make improvements in the 1960's. That's when the turbine engine was produced which provided more power. The most recent improvement has been the electronic controls that have been installed. The first level of safety that they now check is to ensure that a basic design will not fail within certain constraints. Secondly safety is the backup is the level of protection fails for any reason it can not be used.



You can now basically drive a helicopter by its self with little steering involved. The body frame and shape of helicopters all around the world have changed. Over the years, they've went from seating 1 person. up to seating at least 10. Now if a plane crashes or gets lost or if anything happens. People are able to track it from the ground, or tell the pilot what to do to re-stable the plane. They now come with seat belts and everything you could imagine for the most reliable safety. They rescue people from natural disasters. Save lives, Put out wild fires, etc... Helicopter do almost anything you can design them to. = What helicopters were first used for. =


 * It all started during the Cold War a Russian-born inventor created a military version of the worlds first helicopter. In 1935 the first economical helicopter, called the VS-300 was flown by Igor Sikorsky. After he came up with the first, basic helicopter that shocked the world, his model became the baseline helicopter design for every machine to date. **




 * Sikorsky demonstrated the lifting power of a helicopter to the US Coast Guard in 1944 and that was the beginning of US military helicopters. Helicopters were soon used for military purposes. They were used for things such as observation as well as evacuating wounded from the front lines.At the time the largest helicopters could only carry 2 people. By the start of the Vietnam War there were helicopters that could carry up to 45 soldiers or close to 100 civilians.The Korean War was when helicopters really started to shine. Because of helicopters the death rate from wounded deceased.The reason for this discrepancy is that civilians do not have all of the gear that soldiers must carry.**




 * It was during this interwar period that the U.S. Marine Corps formally adopted vertical envelopment as part of their mission. Vertical envelopment is when helicopters are used to carry soldiers behind enemy lines to strike deep into their supply lines.**
