17 Most Important Airplanes of all Time

by Stanley April 8, 2018
written by Stanley

Airplanes are integral part of human and commodity transportation from one continent to another or even in the same continent or country. The following are some of the important airplanes of all time.

Important Airplanes of All Time.

  1. Spirit of St. Louis. The Ryan NYP, known as the “Spirit of St. Louis,” carried Charles Lindbergh on his landmark 33-hour, 30-minute non-stop flight across the Atlantic Ocean from New York to Paris.

Lindbergh, who was relatively unknown in the aviation community at the time, was unable to procure the funds to acquire a suitable existing airplanes design. Eventually the fabric-covered, single-seat, single-engine airplanes were designed jointly between Lindbergh and the Ryan Aircraft Company.

  1. Rutan VariEze. Designed by famed aerospace engineer Burt Rutan, this unique composite airplane became wildly popular among amateur aircraft builders because of its aerodynamic resistance to spins, its exotic looks, and its simplicity of design. In a departure from the traditional vertical and horizontal tail configuration similar to the tail feathers of an arrow, the VariEze received a Rutan hallmark: a smaller forewing or canard and large winglets at the tips of the larger main rear wing.
  2. Lockheed Martin F-35 Lightning II. Many modern fighters currently in active military roles began production in the 1970’s. As many of these aircraft are reaching the end of their service life, with what is supposed to be an affordable alternative. The F-35 represents an entirely new class of fifth-generation fighter aircraft. Three variations of the fighter were developed to replace the U.S. military’s aging fleet of F-16s, F/A-18s, A-10s, and AV-8B Harrier jump jets.
  3. Airbus A320. To catch up to its biggest competitor, Boeing, Airbus took a leap forward in technology in the late 1980s by widely adopting the use of fly-by-wire flight controls and implementing side-sticks for improved ergonomics for the flight crew. The result is less arm fatigue and more precise control inputs that allow the crew to sit closer to larger integrated flight control instrumentation.

    6.General Atomics MQ-1 Predator. The Predator was the first military “drone” (though the more. It became famous for its role in fighting the Taliban in Afghanistan. The Predator can be remotely piloted to fly over a 400-nautical-mile course, circle its target for up to 14 hours, and return to base. The extensive use of the Predator not only to gather Intel but also to fire Hellfire laser-guided missiles marked the beginning of the modern era of extensive drone warfare by the U.S. military.

     7. Scaled Composites Voyager. Burt Rutan originally sketched this high endurance one-of-a-kind aircraft on a napkin. It went on to be piloted by Burt’s brother Dick and Jeana Yeager, to become the first aircraft to circumnavigate the globe without the need to stop or refuel.

      8. Piper J-3 Cub. The first bright yellow J-3 went for sale in 1938 pumping out a whopping 40 hp and costing a mere $1,000 dollars. With war looming in Europe, the little Cub became a primary trainer for the Civilian Pilot Training Program. By the end of the Second World War, 80 percent of all U.S. military pilots received their primary training in a J-3.

      9. Messerschmitt Me 262. Although engine problems delayed its operational status with the German Luftwaffe, in 1942 the Schwalbe became the world’s first jet-powered fighter aircraft. It was late to the fight in WWII, and engine reliability issues hampered its effectiveness and Allied attacks on German fuel supplies.

      10. RV-3. By quitting his day job to build an airplane of his own design in the garage behind his house, Richard Van Grunsven quietly began the most successful aircraft kit-building company in history.

Van Grunsven continued to build a line of successful kit aircraft based on this original RV-3 for four decades, and the business eventually outgrew two facilities. Now, each year the number of aircraft built that were designed by Van Grunsven outnumbers the combined production of all commercial general aviation companies.

  1. Gossamer Albatross. Designed by American aeronautical engineer Paul B. Mac Cready and flown by amateur cyclist and pilot Bryan Allen, this human-powered aircraft won the second Kremer prize when it was successfully flown across the English Channel on June 12, 1979. Allen completed the 22.2-mile crossing in 2 hours and 49 minutes, reaching a top speed of 18 mph at an average altitude of 5 ft. above the water.
  2. Lockheed P-80 Shooting Star. Despite its very dangerous development period, which killed two top aces and broke the back of another test pilot, the United States’ first turbo-jet powered combat aircraft helped to bring about the jet age.
  3. Dassault Falcon 7X. This French-built business jet used a fly-by-wire flight control system adapted from Dassault’s Mirage military fighter jet. Also borrowed from the Mirage was the extensive use of three-dimensional visualization software for all phases of design.
  4. Gulfstream When the Grumman Aircraft Engineering Corporation came up with the brilliant idea to turn its robust line of warplanes into a fleet of scaled-down airliners to accommodate the post-war economic boom, the business jet was born.
  5. Bell Boeing V-22 Osprey. The ability to take off and land vertically as if a helicopter but cruise at high speed and long ranges like a turboprop became an important need for the United State military in the early 1980s. Boeing and Bell were jointly contracted to develop such a craft to replace the aging fleet of CH-46 Sea Knights.

      16. Wright Flyer. The airplane that made the first successful flight in a heavier-than-air powered aircraft may be the most important airplane of all time. However, do not forget, the Wright Brothers that went far beyond those first few minutes aloft on the beaches of Kitty Hawk. The Wrights’ use of wing warping to achieve bank, in coordination with yaw from the rudder, allowed their craft to be properly controlled. This concept is still used on virtually every plane in the air today.

       17. Supermarine Spitfire. The Spitfire was the only British fighter in continuous production throughout the entire Second World War. It became the backbone of the Royal Air Force Fighter Command and was most noted for beating back the German Luftwaffe during the Battle of Britain. The distinct elliptical wings were designed to have the thinnest possible cross section, which resulted in higher speeds than many other fighters of the day did.

Green Steel Manufacturing

by Stanley April 3, 2018
written by Stanley

Steel is oxygen for industries for being overly used as a raw material. It has a couple of eras, each transcending to a more superior one. The Bessemer process no longer runs the turf of steel manufacturing. Green steel made its debut with a bang and manufacturers have widely adopted the concept. To cast a blind eye on Green steel is being oblivious to a year’s revenue.

What is Green Steel?

Green steel is a steel making process that is a bang for your buck. This new process tows with it abundance in improved quality, cut down costs and the biggest reprieve is that it lowers greenhouse gas emissions. When you implore green steel, emissions become the least of your worries, considering that a good portion of the world’s greenhouse gas is from steel production.

The world’s production of steel is about a billion tons each year. With Green Steel cast in the picture, you are bound not just to produce more but also the crème quality of steel. The icing at the helm of Green Steel is the lowering of greenhouse gas emission. This is half the hassle you encounter with other steel manufacturing processes; two tons of carbon dioxide is generated by just one ton of steel.

Green steel as pioneered by MIT researchers is a win, win, win concept; lowers cost of steel production, produces quality steel and reduces emission of greenhouse gases. In truth, Green steel is a timely intervention because metallurgy is negatively affecting forests. Before fossil fuels initially wood was being used to fuel the hot steel furnaces and this means rapid deforestation.

Green Steel; A NASA Intervention

Green steel manufacturing was discovered during a NASA expedition that sought to give headways on how to produce oxygen on the moon. This mission was using iron oxide in the lunar soil to produce oxygen through molten oxide electrolysis. Interestingly they got steel as a by-product and this was the green steel manufacturing threshold.

The problem however was to figure out how to make the process economical for the iridium anode was expensive. Unlike traditional manufacturing which heats iron oxide with carbon to produce steel, this one uses metal oxide electrolysis and iridium anode as a catalyst. Chromium anode alloy is abundant for the whole process and in turn cuts down the cost by half.

The Intrigue behind Chromium Iron Alloy

Take it from Donald Sadoway; the MIT professor of material chemistry alludes it was hard to find a material that would suitably replace iridium anode. The new paper senior author flashes back the aggressive melt they would face when oxygen reacted with the metal. Moreover, a vat of molten oxide needs to be kept at 1600 degrees Celsius. If you connect with this, it is a tough environment to counter.

Enter chromium iron alloy. This alternative material was explicit in design. First off, it is thin enough to allow electric current to flow through it and it forms a thick metal oxide to prevent further penetration by oxygen.

Green Steel Manufacturing vs. Traditional Manufacturing 

This MIT spawned process can do something that current used processes cannot. It is suitable to small-scale factories and this feat is one traditional manufacturing cannot compare. It limits carbon emissions and boosts production to meet the ‘economical’ scale of steel production. It stands now that for s steel production to be economical it needs to produce at least a few million tons of steel annually.

Green steel manufacturing is salvage for small-scale factories for it allows them to generate a few thousands of tons of steel per year. Green steel manufacturing changes the whole game of steel manufacturing simply:

  1. Exceptional purity.

Green steel allows for production of pure steel.

      2. Easy adaptation.

Green steel manufacturing is freely adoptable into the carbon -free production of a variety of metals and alloys like such as nickel, ferromanganese, and titanium.

The only thing left out for green steel manufacturing to quantify is if it will be cost effective against other already established systems. This is because the process has not been legislated yet to account for production of its greenhouse gases for it is only this, which will determine which process is better in a phase-off.

The whole scope of green steel is vast and takes time to manifest fully. For instance, the pioneer researchers are forming a company that will endeavor in further developing this process. Within a span of 10 years to come green steel manufacturing will breach the now vague boundaries.

A Viable Prototype Electrolysis Cell     

Imagine how convenient a prototype electrolysis cell will be! Steel production will be fluent for all and it might even go beyond the economical scale of steel production. This is the foresight of a few individuals whose utmost desire is in the next three years to have already designed and tested out a prototype electrolysis cell. What is more is the cell intends to be commercial so that steel manufacturing becomes easier.

Sustainable Steel at the Center of a Green Economy

Someday in the future probably, you will start to see steel manufacturers starting to certify steel products for use.  This is the dream of Veena who is responsible for inventing green steel manufacturing. She envisioned this process should be the resolve for greenhouse gases emission through making steel by using recycled rubber tires.

Veena, an Indian native could see the 10,000 metric tons of waste produced a day besides her home city, Mumbai being the electronic waste dispatch for India. This sparked a genuine science and technology fancy in Veena so she chose to pursue science and engineering.manu4

She broadened her horizons by studying in other countries like the United States and Canada. She would see how people associate with rubbish, not wanting it in their backyards and it made her think of how to re-use rubbish.

What blossomed green steel was when she started to think about how to re-form the waste that cannot be recycled?  Green steel manufacturing will allow for generation of new-age products. For instance, you can take out of a windscreen glass the valuables and make new-age products. No more landfilling waste and energy efficiency becomes the mantra of green steel manufacturing.
