Every action has an equal and opposite reaction.
To decelerate the aircraft, the forward thrust of the aircraft which propels the aircraft forward is reversed by a Thrust Reverser. This is accomplished by redirecting all the air ( in small engines ) or partially ( in larger engines ) to the front.
Due to the flow of air to the front end of the aircraft, a reaction force acts in the opposite direction to the motion of the aircraft. This aids in the deceleration of the aircraft.
Engines with no Pistons- Wankel Engines.
Behold the Wankel Engine - An engine which operates without any piston strokes.
Revolutionary Duke Engine.
The Duke engine is a four stroke "axial" reciprocating engine. "Axial" because the axis of each cylinder is aligned with the axis of the output/crank shaft.
The most immediately obvious advantages of the Duke Engine are its size and weight when compared to late model conventional internal combustion engine.The current prototype Duke 3-liter engine is up to 19% lighter than those two engines, despite being far from optimized for minimum weight.

This fantastic music video by Kim Pimmel is a beautiful merger of art and fluid dynamics. Using household goods (and some slightly more exotic ferrofluid), the video shows how mesmerizing diffusion, buoyancy, Marangoni flow, and other fluid effects can be up close. It may also be the first time I’ve ever seen fluid dynamics—specifically bubbles—used as characters! Also be sure to check out some of his previous videos, many of which also feature cool fluid dynamics. (Video credit and submission: K. Pimmel)
A brief history of F-1 (Part-1).
Okay, let’s get revved up. In this post, i will try to establish what Formula-1 actually is by answering some basic but yet integral questions.
Why is it called “Formula” -one ?
The term “Formula” in Formula 1 essentially refers to a set of regulations that govern any of several forms of single-seater open wheeled motor sports. Typical regulations that are specified include:-
Restrictions on the type of chassis to be made
Restrictions on the type of engine to be used, essentially limits on the maximum engine displacement
Restrictions on the gearbox to be used
Other competition specific regulations, specifically conduct rules such as refueling rules, pit stop rules etc.
Restrictions are generally not put on suspension, braking, steering and aerodynamics and the teams are generally free to do whatever they want in these fields. All of these regulations make up the “FORMULA”
Is there a formula- two ?
Yup, not only formula two, but formula three as well ( These are most popular ones,but many more do exist). The distinction of these is based on the ‘Formula’ that govern it. Formula 1 consists of the best performing cars (in terms of power and max. velocity) and followed by Formula 2 and 3. And hence the chronological placement of numbers 1,2 and 3.
What is a Grand Prix?
Grand Prix is any of a series of motor-racing or motorcycling contests forming part of a world championship series, held in various countries under international rules.
The first race to be given the title "Grand Prix" was held at Le Mans in 1906. It was restricted to "big cars", which could be described as the "Formula One" cars of the period. From then on, the term Grand Prix became associated with major circuit races for cars. Top events, which were the equivalent of today's Grands Prix, were called "Grandes Epreuves" (Great Events). However, the FIA was opposed to the popular usage of the "Grand Prix" title, which it wished to reserve for events counting towards its Formula One World Championship. Henceforth, it was prohibited to use the Grand Prix title for an event which did not count towards this Championship, except for very rare cases with historic justification, such as the Grand Prix de Pau, which is currently a Formula 3 event.
A list of the formula one Grands Prix can be found here.
Can any driver compete in a Grand Prix?
No. In order to be able to take part in a Grand Prix, a driver must hold a "Super Licence", which is awarded on the basis of his past record in junior formula and of his having a valid contract with a Formula One team which has entered the World Championship.
How are the laps are timed in F-1?
Each car has a transponder unit fitted to it (they are fitted beside the cockpit and in the front of the chassis ), the transponder has a ID unique to each car and it will transmit this ID when the unit is energized by passing over a timing loop buried in the track surface. These transponders allow the timekeepers to record every lap time of every car throughout the weekend. ( The use of a transponder unit for lap timing is also used in other motor sports )
Facts and Trivia Section:
Do you know the logo?
The Formula 1 logo has a hidden number 1 between the letter F and the speed lines. Surely most of you out there think “F” signifies ‘Formula’ and the red-coloured design signifies “1″. But in reality it is not the red-coloured design, it is in fact the white space between the black coloured “F” and the red-coloured design that signifies “1″. Meaning of the colors :The red color represents passion and energy, while the black color represents power and determination.
Unveiling the F1 enigma series.
Formula one or F-1 is one of the most prestigious and technologically advanced sports in the world.The never-ending battle for supremacy makes F-1 one of the most competitive, expensive and demanding sports in the world.
It is a game of chess played at 300 Kmph.The real war though is fought behind closed doors in the secrecy of the team's headquarters.
As March 13 marks the start of a new season of this motor sport, we decided that it was high time we unveil the technology that underlies the stardom of the automobile industry - The formula one car.
From questions like what enables a formula one car to go upside down a tunnel? to awfully simple questions like does the F-1 car have an ignition key and why not? we will try to cover it all. Most importantly, we will try to weave what you already know to explain new concepts.
The rough list of contents for this series are:
A brief history of Formula one.
Aerodynamics- The art of glueing the car to the ground.
The nucleus of the car- F-1 engine and the gearbox.
One has to stop!! -Brakes and steering wheel.
Tyre and fuel technology- This rarely is given the importance that it needs.
Fun facts and trivia with every post.
If you have any questions that you have in mind to be answered and topics that we have missed, please post it in the comments section below. We would be delighted to address them.
Hang onto your hats, it's going to be a wild and crazy ride ahead!
Deep Draw Technology
Deep draw metal forming is a process where flat sheet metal is formed into more complex components, such as battery cell cans. A disc of sheet metal is blanked from a coil of sheet metal in the first station of a series of dies. The flat blank is then cupped by the "nose" of a punch and pressed into a die to form a cup.
During the drawing process the metal is formed under significant pressure. The material wall sees tension forces and the blank flange sees forces of compression. These forces are manipulated by the design of the tooling as the material is stretched by the “nose” of the punch into each die. These forces tend to thin the shell wall and thicken the shell flange. Depending on the material, the ratio of starting wall stock to finished wall stock, and the length to diameter ratio, a varying number of draws are required to create the basic shape of the part.
The drawing process can create stepped diameters or other unique features in the part. The drawing action also work hardens the material, making the finished seamless part stronger than the base material. Tooling is added to the basic dies to create other features such as: coining, bottom piercing, multiple side piercing, extruding, embossing, marking, burnishing, ironing, chamfering, flange forming, shaped flange trimming, beading, reverse drawing, and rib forming. The deep draw process produces a strong, thin wall container in aluminum, steel, stainless steel, or other metals.
