Anti Lock Braking System

It's a fact. Everyone loves driving these days. That feeling of holding the wheel where we are in charge of our own destiny is rare in our lives. Trust me, it is very welcoming and exciting.
Many of us are speedsters, especially on a highway when you hit 100 km/hr. It is very fun and thrill inducing. However, during monsoons or ice cold weather the situation gets tricky. Sometimes your wheel might lose traction and start to skid on the slippery road. For that very reason, we have something called the Anti-Brake system in our cars.



Without anti lock braking system, there are chances where the wheel might stop rotating and the result would be deadly. ABS prevents your wheels from locking and ensures that you have stability. 
It consists of four major parts.

1. Speed Sensor: The major function of this is to monitor the speed of all the wheels and to provide the necessary acceleration and deceleration. It consists of a magnet assembly which generates electric pulses.
2. Valves: They are used to regulate the pressure in the brakes. There are valves present at every brake in the brake line. The first position is when the valves are open where the pressure from master cylinder is transferred to the brakes. The second position is when the valves are close where it restrains the force. The third position is when it allows some pressure to the brakes. The third position is used for the car to come to a halt.
There are two hydraulic valves in a typical ABS system. The resistance you feel while braking at high speeds are the valves controlling the pressure.

3. Electronic Control Unit: This part basically receives signals, amplifies them to determine the speed                        
and acceleration. It also receives signals to control the brake pressure. All the relevant data is analyzed in this unit.

4. Hydraulic Control Unit: This unit receives signal from the electronic control unit to control the brakes. This is done by either reducing the pressure on the brakes or increasing the hydraulic pressure at the brakes when necessary.
Any ABS unit should consists of four wheel sensors, 2 valves at the brakes, an electronic control unit and a hydraulic control unit. It is very important to keep in mind that ABS just supports the driver however it depends on the driver to maintain a safe speed and certain gap from the vehicle in front.

Materials used in Turbine blades

Image
There has been a wide range of materials used for the manufacturing of gas turbine blades. It is one of the most important parts in a gas turbine and any deterioration of it will affect the performance and efficiency of the turbine and most importantly will damage the turbine.  Many materials have been tested and used but the most preferred materials include steel, titanium, Nickel based super alloys and ceramics. The first stage of the compressor is very delicate as it is subjected to a very high temperature of approx. 1400-1500 degree celsius.  This part of the turbine should tolerate high temperatures, high pressures, high thermal stresses including creep and fatigue, vibrations which can influence it's performance. The first stage uses Udimet 500, Nickel based super alloy Inconel 738 or GTD 111.  The relatively cold stages of the turbine employ titanium as there are chances of it igniting when used above 500 degree celsius.      ...

Self Energizing Brakes

Image
The usual drum brakes in our car are provided with a remarkable feature called 'servo' or 'self energizing' feature. It is this feature that is responsible for the smooth and flat application of brakes in automobiles. When the vehicle is moving left, in the forward direction, then the drum will rotate in the anticlockwise direction. When the brake pedal is suddenly pressed, the two brake shoes at the drum will have full contact with the drum. However, one of the brake shoes, the primary brake shoe tends to slip for a certain distance in the drum's direction. Due to this, the primary brake shoe will tend to apply a rearwards force on the secondary brake shoe at the bottom. The wheel cylinder at the top forces the piston against the top of both the brake shoes. Due to this, the secondary brake shoe experiences force on both the sides i.e the top and bottom side.  This ensures that the brakes are applied uniformly and much less effort is applied.

3 spool vs 2 spool

Image
In the Trent 1000, there is 3 spool arrangement of compressors and turbines. This means that there are three sets of compressors and turbines which are connected by three separate shafts. They are the low pressure compressor (LPC) which is the fan and turbine (LPT), Intermediate pressure compressor (IPC) and turbine (IPT) and high pressure compressor (HPC) and turbine (HPT). This is on contrast to the two spool arrangement currently used in many aircrafts where a LPC/LPT and HPC/HPT are used only. All the three shafts are located within each other. The fan positioned at the front of the engine is run by the LPT via a gearbox so that it can operate at optimum speeds. Since the large diameter fan requires a large torque to start rotating, it limits the high speed attained by the LPT due to which its efficiency decreases. Additions of an additional set of compressor and turbine eliminates the influence of this problem but does not eliminate the problem itself! The problem is elim...
