Aerodynamic Road Test Techniques To Measure Lift and Drag Forces Hill Rolling Method Hill rolling method comprises of allowing vehicle to roll down on a hill of uniform slope up to a fixed terminal. The terminal velocity of a vehicle is a function of all forces acting on the vehicle. The forces other than aerodynamic…
Aerodynamic Forces and Moments acting on the Vehicle Body In order to analyse the various aerodynamic forces and moments acting on the vehicle body, consider the vehicle as a mass having six degrees of freedom. Now the various aerodynamic forces acting on the vehicle body can be summarized as follows: Px – Force of air…
What makes a vehicle aerodynamics? Vehicle Aerodynamics is a potential area to minimize the fuel consumption. Because the air drag acting on the vehicle is directly proportional to the square of the vehicle speed. So by thoroughly studying and by providing necessary modification the drag force is reduced and there by the following advantages can…
SolidWorks COSMOS Applications in Aerospace and Automotive Industries SolidWorks COSMOS has been used in the aerospace industry for wide ranging applications involving kinematic analysis, Finite element analysis and Fluid flow computation. Some of the Solidworks COSMOS Applications capabilities include: Shock and vibration calculations Durability and Fatigue Life Estimation Modal Analysis and Frequency response calculations Weight…
Advanced Battery Storage Technology For decades, Advanced battery storage technology has been a heavy weight on the back of scientific innovation. From cell phones to electric vehicles, our technological capabilities always seem to be several steps ahead of our ability to power them. Several promising new technologies are currently under development to help power the…
New Battery Technology Fast Recharge Batteries Of all the criticisms of electric vehicles, probably the most commonly-heard is that their batteries take too long to recharge – after all, limited range wouldn’t be such a big deal if the cars could be juiced up while out and about, in just a few minutes. Well, while…
Kinetic Energy Recovery System (KERS) The introduction of Kinetic Energy Recovery Systems (KERS) is one of the most significant technical introductions for the Formula One Race. Formula One have always lived with an environmentally unfriendly image and have lost its relevance to road vehicle technology. This eventually led to the introduction of KERS. KERS is…
How Fuel Cells Work An electrochemical reaction occurs between hydrogen and oxygen that converts chemical energy into electrical energy. Think of them as big batteries, but ones that only operate when fuel—in this case, pure hydrogen—is supplied to them. When it is, an electrochemical reaction takes place between the hydrogen and oxygen that directly converts…
Fuel Cell Car Fuel Cell Stacks This is the heart of the hydrogen fuel cell car—the fuel cell stacks. Their maximum output is 86 kilowatts, or about 107 HP. Because hydrogen fuel cell stacks produce power without combustion, they can be up to twice as efficient as internal combustion engines. They also produce zero carbon…
Super Charger Engines combust (burn) fuel and use the energy of that combustion to do work. The more fuel that is combusted in any given time then the more energy is available to carry out the engines task. Fuel requires air (or the oxygen contained within air) to burn so if there isn’t enough air…
Turbo-Charger A turbocharger is actually a type of supercharger. Originally, the turbocharger was called a “turbo super charger.” Obviously, the name was shortened out of convenience. A turbocharger’s purpose is to compress the oxygen entering a car’s engine, increasing the amount of oxygen that enters and thereby increasing the power output. Unlike the belt-driven supercharger…
Variable Turbo Chargers Variable geometry turbochargers (VGTs) are a family of turbochargers, usually designed to allow the effective aspect ratio (sometimes called A/R Ratio) of the turbo to be altered as conditions change. This is done because optimum aspect ratio at low engine speeds is very different from that at high engine speeds. If the…
The Air Car caused a huge stir when we reported last year that Tata Motors would begin producing it in India. Now the little gas-free ride that could is headed Stateside in a big-time way. Zero Pollution Motors (ZPM) confirmed on Thursday that it expects to produce the world’s first air-powered car for the United…
Air Car Is Heading For Mass Production The Air Car is the brainchild of Guy Negre, a French inventor and former Formula One engineer. In February, Negre’s company, Motor Development International (MDI), announced a deal to manufacture the technology with Tata Motors, India’s largest commercial automaker and a major player worldwide. “It’s an innovative technology,…
