The F 22 raptor! the best aircraft in the world and i mean "THE BEST"

Yess the most expected aircraft post on my blog is here particularly keeping the design in perspective...I wont go into the technical details where u 'll find everywhere else but give you an insight to what an airplane like the f-22 actually means to aviation designing............lets go back to the time around WW2  when the radar was first invented.It was supposed to be "The" machine the defence forces would fancy, having it.It was used mainly for keeping a strict vigil on the airspace of a whopping area of about 400 km in all directions.You could know about attacks about 2 hours ago and the list keeps on going.About 1.5 decades ago the idea of an "radar invisible" aircraft  was thought of .It seemed as an arguably impossible idea as u could not build the plane out of fluids which wouls absorb the radiation instead of reflecting it back, but no one thought of it this way ie.. deflecting away the radiations . Then the engineers at Lockheed Martin came up with a combination of factors such as radar-absorbent material-coated S-shaped intake ducts that shield the compressor fan from reflecting radar waves, the F-22 design placed a much higher degree of importance on low observance throughout the entire spectrum of sensors including radar signature, visual, infrared, acoustic, and radio frequency.
The most important tactic in today's warfare is the Element Of Surprise which u give to the enemy and the f-22 provides it to the last ounce ............stealth..The stealth of the F-22 is due to a combination of factors, including the overall shape of the aircraft, the use of radar absorbent material (RAM), and attention to detail such as hinges and pilot helmets that could provide a radar return.[153] However, reduced radar cross section is only one of five facets that designers addressed to create a stealth design in the F-22. The F-22 has also been designed to disguise its infrared emissions to make it harder to detect by infrared homing ("heat seeking") surface-to-air or air-to-air missiles, including its flat (rather than round) thrust vectoring nozzles.[154] Designers also made the aircraft less visible to the naked eye, and controlled radio and noise emissions.[153] The Raptor has an under bay carrier made for hiding heat from missile threats, like surface-to-air missiles.[155].................................Too much i guess....thats all for now and keep commenting om my posts  so that i can make them better and better.

List of aviation innovations that have been "infamously overshadowed"!!!!!!!!!........

It seems all news is bad news when it comes to aviation these days, and it’s too bad because it overshadows just how wonderful it is that we can fly. Think about it — 100 years ago, few could imagine it. Today we take it for granted.

It’s an amazing accomplishment, and too often people lose sight of that. Aviation Design has compiled a list of the greatest innovations of aviation that have taken us ever further and faster in the 100 years since the Wright Brothers took wing. It includes things like the monoplane, transatlantic flight, the steam catapault and human-powered aircraft.

We looked at their list, tweaked it a bit and came up with our top 12 because 10 wasn’t enough.


1. Cabin pressurization — The average passenger doesn’t think about cabin pressurization until their yellow safety masks fall from the ceiling, but the reality is that if the technology hadn’t been developed during WWII, we wouldn’t be able to fly much above 10,000 feet.

2. Black Box — Morbid but essential, the black box was invented in the mid-1950s, and not only helps investigators learn why a plane crashed, but how that information can be applied to other aircraft to prevent a repeat.

3. The Concorde — It never delivered on its commercial promise, and it was an environmental bad boy, but who can deny that breaking the sound barrier aboard a commercial aircraft is cool. And have you ever seen a more beautiful plane?

4. Radar — Sure, the airlines are dying to replace it with GPS technology, but for decades it’s been radar that helps air traffic controllers locate and track planes up to 200 miles away. Would our modern air traffic infrastructure exist without it? Probably not.

5. The jumbo jet — Whether you think they’re graceful or ungainly, you can’t deny that jumbo jets have changed the face of commercial aviation. The economies of scale provided by a 400-seat airliner meant airlines could offer cheap tickets that made it possible for the masses to fly.

6. The hub and spoke system — People hate, hate, hate having to make stopovers at jam packed airports controlled by a single airline. Yeah, they’re expensive to fly into and delay prone, but hub airports are a big part of the reason that you have 20 flights a day to choose from when flying between most large Metropolitan cities.

7.The Very Light Jet (VLJ) — It’s been a tough road for the VLJ, with manufacturers suffering production problems and customers going out of business, but that doesn’t diminish the allure of a 37 foot, 3,500 pound plane designed to carry four to six passengers on short hops that would otherwise require a car ride.

8. Winglets — Here’s another one that most of us don’t think about. The small upward-pointing extensions at the tips of aircraft wings reduce drag, improve climb performance, increase range, and make flight more fuel efficient. With oil at over $100 a barrel, no wonder most airlines have added winglets across their fleets.

9. The flying wing — Yves Rossy keeps breaking records and defying expectations with his 8-foot-diameter, carbon composite flying wing. Sometime back he made a successful 13 minute, 125 mph trip across the English Channel.

10. Stealth aircraft — What’s cooler than a plane that can outsmart radar? Because the surfaces of a stealth are designed to absorb radio waves or reflect them away from the receiver, stealth planes can sneak in and sneak out undetected. Too bad they’re so expensive: The 21 plane B-2
program cost over $45 billion.

11. Jetway — Another one most of us don’t think about is the long covered walkway the connects our departure gate with our plane. It means we don’t have to wait outside on the tarmac in sleet and rain, or contend with the shriek of jet engines. The A380 is served by three jet bridges, one of them leading directly to the first class lounge.

12. Deicing — Ice buildup is the cause of many fatal aircraft accidents, which is why applying monopropylene de-icing fluid to wings pre-flight has become standard operating procedure. Without it, air traffic would ground to a halt every time things got a little stormy.
Hope you found my collection interesting

Planes can use 75% less fuel with design improvements....................am i kidding??

And yes the true potential of changing or modifying the design of an airplane are coming to light!! Researchers at MIT claim they have come up with a design which could use as much as 70-75 % less fuel, and that is huge savings for airlines and the defence forces and the savings will run into billions of dollars.The proposed design has advanced airframe configurations and propulsion systems which will seriously help in fuel reduction ....even i dont know how as the idea is too early to realized !! but anyhow we should hope that such exceptional designs materialize and do the good for future generations.Take a look at this link to get a clear idea about this whole concept.............................I ll be up with such interesting topics shortly.............keep reading and dont forget to fasten ur seatbelts(even though the air hostess reminds u to)!!!!!!!!!!!!!!!!!!!!!

The Gee Bee revolution..........

The Gee Bees , yes the airplane u see in the background of this blog, is one of the most influential planes in history especially in design.It was one of the first marked evidence of designers and engineers shifting from traditional aircraft design that is why i chose it as my background.It was an airplane used for racing and acrobatic events.If  u notice, the tail portion and the cockpit is merged into one and the tail does not have a predominant airprint! The reason: many of u would laugh but its to reduce the stability of the plane so that manoeuvreing the plane during stunts is easy and simultaneously provide " just enough control " using the rudder. Many critics believed the plane would just not take off even if it did it would totally be in the mercy of the nature.And the fuselage.....where is it? there s nothing as such as a fuselage in this craft! Its all merged into one...the engine compartment along with the cockpit and the tail.Its basically a compressed version of a traditional airplane but nevertheless it was a revolution in aircraft designing .Coming back to fuselage it has a tear drop design which predominantly has less drag than the tapered design and the main reason for the cockpit situated at the rear is that it gives better visibility to the pilot while performing pylon turns while racing.It also had the reputation of being one of the dangerous machines to fly as it had small control surfaces and as i mentioned earlier , quite unstable in flight.Due to this many accidents occured and the production of this airplane stopped.Whatever be the case it serves our purpose of inspiration for attempting new design in the aviation world.Hope u liked today's post watch out for more........................................!!

My First ever post...

Let me introduce you to this unexplored world of aviation designing,its the backbone of the aviation industry(defence as well as commercial) Its redefined the way we look at airplanes.For the time being just consider yourself designing an airplane.It would be somewhat like two wings stuck to an almost cylinder with some added extras.If u picturized that, thats the way 98% of the population (approximate figures)designed one.If u take a look at the airplanes such as  B-2 Spirit and F 22 Raptor they have totally redifined the airplane design.They are better than never before with unmatched fuel efficiency and speed.They are the new generation crafts.From an engineer's point of view " a piece of master art" . Imagine for a while if all the new aircrafts that were designed have the same shape as mentioned earlier what will happen to the aviation sector.It would be stagnant with no new oppotunities .Its like flying in the same plane after 25 years and still it will be considered the latest design.I hope u got a clear idea whats it all about and watch out for my interesting posts.
