A New Twist on Airplane Wing Design

In one of his greatest work “Codex on the Flight of Birds”, Leonardo da Vinci provided some unique study with almost 500 sketches of flying machine, which is the basis of modern Airplane technology in the contemporary society. The Wright brothers have accomplished the maiden powered flight over hundred years ago, which was controlled by using pulleys and wires to twist and bending of the wings, made of wood and canvas.

Although this system is a quite different one, that is propelled by hinged flaps and the ailerons, which are being used in most of the aircraft since its inception. The aircraft technology has developed in many ways in the last few decades and witnessed some of the most advanced elements in the design and technical know-how.

Now the engineers from MIT and National Aeronautics and Space Administration (NASA) have developed some hi-tech enchantment, with a new version of bendable and “morphing” wing. This new technology is having some unique features and simplified process of manufacturing that reduces the consumption of fuel by improving the aerodynamics of wings. Some of the features of this basic concept are as follows:
  • The fundamental principle at the back of this new concept is the simple use of an arrangement of tiny and lightweight structural components, which are referred as “digital materials” and can be assembled into almost infinite assortment of shapes. This is such a simple structure manufacturing that can be compared even with the formation of configuration with the help of Lego blocks. The separate pieces are quite strong and rigid in nature, but it can be noted; the precise choice of sizes and the materials and most importantly the geometry of the assembling of pieces, which allow for the exact tuning of suppleness of the shape.

  • According to researchers; the building up of such large and intricate structure, from an arrangement of tiny and indistinguishable building blocks, which have the exceptional grouping of strength, flexibility and light weight, simplifies the manufacturing process to a great extent. This modular structure is also providing the greatest ever simplicity in both the assembly and the disassembly of the construction that means; when the structure is not been needed, it can be dismantled and the entire structure can be taken apart by segregating its separate component parts, which can be reassembled and used for creating some other kinds of structures.

  • Being the composition of different tiny parts; repairing process is also very easy and can be done in a very simple manner e.g. just by replacement of the damaged subunits in a very comfortable manner. The “skin” or the outer coat of the wings is also enhancing the performance of the structure. This “Skin:” is made with the technology of overlapping strips, made of flexible materials and layered as bird’s feather or somewhat like fish scales, which allows the pieces in moving across, while the wings flexes but still provide the most smoothened outer surface. It is ascertained that the primary use of this technology can be for making of tiny and robotic aircraft at the initial stage.

4,000mph Hypersonic Plane Backs Revolutionary Sabre Engine

Our world is becoming so fast that even a few minutes or seconds delay can cause huge losses and problems for us. Transportation and communication sector has gone through a rapid phase of development in the recent past which helped in lowering the costs and time taken for travel along with increasing the mobility.

European Space Agency is looking to make people lives more fast literally by investing $11 million for developing a hypersonic engine with the ability to fly anywhere across the planet within four hours. Reaction Engines has landed up with the job of developing such engine turbine which encompasses the technologies of both jet and rocket in order to achieve an unbelievable five times the speed of sound. Reaction Engines have confirmed that they will be able to come up with the first prototype for testing by the year 2020.

Reaction Engines were going through the period of securing investment from the companies and agencies. So far it has secured about $66 million from the British government and $55 million from the UK Space Agency. The development of the aircraft is still in its preliminary stages and it will take about 20 more years to make it reality on a grand scale.

How Sabre Jet engine works? 

Reaction Engines are working on the revolutionary Sabre engine which would eventually allow aircrafts to take off from the runway and get to the fives times the speed of sound within few seconds. Later on aircraft can switch to the rocket mode thereby propelling the craft right into the orbit. The important part about the Sabre engine is that it works on the theme of burning the atmospheric air in its combustion chambers. Then it makes use of the heat to turbo-charge its engine.

It should be noted that currently rockets have to carry extremely expensive fuel in the name of liquid oxygen and liquid hydrogen in order to power. Sabre engine will certainly help in cutting down the cost as it creates its own liquid oxygen which happens within a blink of an eye. Sabre engine comes in the new class of aerospace engine which has been designed to enable crafts to get to five times the speed of light from the standstill within few seconds.

Sabre Engine is set to revolutionise the transportation

Once the aircraft loaded with the Sabre engine gets its space then it will be able to switch to the rocket mode. In the rocket mode aircraft can travel the orbit for a stimulated period of 36 hours. Thereby such aircrafts can even be used for launching the satellites into the orbit at a fraction of current costs.

UK Space Agency is investing and collaborating with the Reaction Engines to develop the Sabre engine and aircraft which can be used to travel longer distances within shortest time intervals. UK Space Agency has invested 60 million pounds in 2013 with an aim of developing some ground breaking technology and Sabre engine is a result of its effort.

Future Supersonic Aircraft Tested by NASA!

After the crash of July 2000, the Concorde was finally placed permanently on the ground in November 2003. Ten years later, a new supersonic aircraft will perhaps make its appearance in the sky and has just been tested on the premises of NASA. As Concorde is no longer in 2003 (it is still open to the public at the Museum of Air and Space at Le Bourget), a new successor looks set to take over from the supersonic adventure. This is the U.S. aircraft manufacturer Boeing launched the site of the new aircraft sleek aerodynamic design. Everything is done for speed exceeds the sound barrier. It is that the device, which has no name yet, was tested in the premises of the Glenn Research Center of NASA in Cleveland, Ohio. This experimental research center has a blower ("wind tunnel") long and a few meters wide which have been tested in a replica of the prototype.

 A dedicated page on the NASA website explains that "researchers are testing the overall design and performance options to reduce vehicle emissions and noise, and to determine whether the volume of sonic booms can be reduced to a level that would lead to a reversal of the current decision does not allow commercial supersonic flight on earth.” For now this prototype still looks to be in phase of intensive testing, but it is hoped that the engine Boeing will be approved quickly and move people in the near future. Traveling the world at supersonic speed ... We'd love to! Especially since everyone has not had the chance to board the Concorde! Meanwhile, the images of this aircraft make us think of the many Pok√©mon. How does it feel to know that the Concorde will surely have a successor?
