IndiGo Airlines' record deal with Airbus

Indian budget airline IndiGo has signed an agreement to buy 180 Airbus A320 aircraft, the European plane maker said, in a record sale worth USD 16.4 billion.
      
"It is the largest single firm order number for large jets in commercial aviation history," Airbus said in a statement, although the company has signed contracts worth more financially.
      
The low-cost airline has signed a memorandum of understanding to acquire 150 single-aisle A320neo jets. The neo versions -- "new engine option" -- are equipped with more efficient engines and fuel-saving wing tips.
      
IndiGo is the first client for this new version of the aircraft, which Airbus only unveiled last month and plans to start delivering in early 2016. The other 30 planes are to be standard versions of the A320.

Aircraft Hydraulic System

aircraft hydraulics


Aircraft Hydraulics is a means of transmitting energy or power from one place to another efficiently.
 What is hydraulic technology?
In the hydraulic technology we transmit and control forces and velocities by transmitting and controlling pressure and flow. In nearly every kind of technology we use hydraulic drive and control techniques. A few examples are:

 mechanical engineering 
 car technology 
 agriculture technology 
 earthmoving and mining technology 
 ship building technology 
 offshore-technology 
 aircraft and spacecraft technology

Aircraft Electrical System

electrical system

Most small aircraft are equipped with a 28 volt direct current electrical system. The system is powered by an Alternator which drives the electrical devices and stores energy in the battery.

The Master Switch (labelled MS) causes the electrical system to connect the electrical buses and devices to the battery. The battery provides the power to crank the starter. Once the engine is running, power is supplied by the alternator and the battery is recharged.

Numerous circuit breakers feed off the Primary Electrical Bus, and provide individual circuits to power the electrical devices. Although the arrangement will vary from one make and model aircraft to another, the basic principles are the same. By providing numerous circuit breakers and dividing the electrical load into several different circuits, a malfunction in one system can be turned off without adversely affecting the other circuits. The breakers will be labelled as to their general use, and the amperage will be marked on the face of the breaker push button. On older model aircraft, fuses are used instead of circuit breakers.

RECIPROCATING-ENGINE OPERATING PRINCIPLES

RECIPROCATING-ENGINE OPERATING PRINCIPLES
The reciprocating engine is also known as an internal-combustion engine. This name is used because the fuel mixture is burned within the engine. To understand how a reciprocating engine works, we must first study its parts and the functions they perform.

The seven major parts are:

(1) The cylinders
(2) The pistons
(3) The connecting rods
(4) The crankshaft
(5) The valves
(6) The spark plugs
(7) A valve operating mechanism (cam).
Refer to the relative location of these parts in Figure 6-2 .

Engine Operation.

   The cylinder is closed on one end (the cylinder head), and the piston fits snugly in the cylinder. The piston wall is grooved to accommodate rings which fit tightly against the cylinder wall and help seal the cylinder's open end so that gases cannot escape from the combustion chamber. The combustion chamber is the area between the top of the piston and the head of the cylinder when the piston is at its uppermost point of travel.

Automatic Direction Finder (ADF)

ADF (Automatic Direction Finder) is the radio signals in the low to medium frequency band of 190 Khz. to 1750 Khz. It was widely used today. It has the major advantage over VOR navigation in the reception is not limited to line of sight distance. The ADF signals follow the curvature of the earth. The maximum of distance is depend on the power of the beacon. The ADF can receives on both AM radio station and NDB (Non-Directional Beacon). Commercial AM radio stations broadcast on 540 to 1620 Khz. Non-Directional Beacon operate in the frequency band of 190 to 535 Khz.

ADF COMPONENTS ADF Receiver : pilot can tune the station desired and to select the mode of operation. The signal is received, amplified, and converted to audible voice or morse code transmission and powers the bearing indicator.
