Aircraft Maintenance Engineering 3-Spool-Engine Concept

Aircraft Engine Maintenance 3-Spool-Engine Concepts

What is triple spool design on the RB211? what are the advantages/disadvantages?

A 3 spool engine is one that has three sets of compressors before the combustor and three sets of turbines behind it.

A spool is made up of a compressor and a corresponding turbine used to extract the power from the exhaust gasses to turn the compressor.

Each spool is given a name. N1, N2, and N3. N1 is the large fan section in front of the engine. N2 is the low pressure compressor section. And N3 is the high pressure compressor section. Some engines incorporate N2 And N3 into one rotating mass and call it N2. Hence the double spool engine.

Each section of the compressor wants to rotate at it's own speed, and if allowed to do so as in a triple spool engine, it is able to operate more efficiently. It can turn at it's optimum speed, and not have to compromise between the optimum speed for the N2 and N3 sections when attached in the double spool engine.

All modern engine have 2 sets of compressors (HP and LP) and a fan section providing a vast majority of the thrust.

In a 2 spool motor the HP section and the LP section are joined. The number of spools in an engine tells how many sets of compressor blades and corresponding sets of turbine blades the engine has. A single spool engine has one set of each, a double spool engine has two sets of each, and a triple spool engine has three sets of each.

3 Spool Engine advantages and disadvantages:
  • More sets of blades results in a greater engine weight, but the corresponding increase in thrust possible more than offsets the weight increase.
The drawbacks of a 3 spool engine are increased weight, complexity, and cost to purchase and overhaul, but they are the most efficient engine flying.

Aero Engine Triple Spool Design minimize Engine Surges is the majar advantage of 3 Spool Concept

Major advantage of triple spool design is it's ability to minimize engine surges thus they are the most efficient engine flying.

As mentioned by JETPILOT, namely that the more spools you have, the better because then they will be allowed to spin at their own speed given their spool mass.

Let's say you're at takeoff power with for example a double spool engine. The heavy N1 spool is turning at it's own RPM and so is the lighter N2. Now you chop off the power. The lighter N2 will drop in RPM much quicker then the heavy N1 with it's huge fan. So what happens is that the N1 compressors are feeding way too much air to the second (HP) compressor.

Where is all that excess air gonna go ?
Well in extreme cases you can have a very damaging engine surge in which air will flow in the wrong way through the engine. Most of todays engines have very sophisticated computer controlled "bypass doors" that let the air escape from the compressor casing.
But the chance of engine surges always remains. If you have three spools, the weight difference is spread over 3 spools thus drastically reducing the chance of engine surges.

Tips for Proper Aircraft Tire Maintenance - Goodyear Expert

Aircraft tire/wheel assemblies can lose up to 5 percent of their pressure each day.
When it comes to aircraft tire maintenance, few people in the industry have visited more hangars and seen all manner of service work and maintenance procedures than Goodyear Aviation’s Rob Robson.

Robson is a Product Support Manager for The Goodyear Tire & Rubber Company, and for more than 10 years he’s been immersed in aircraft tire product support for everything from piston singles to helicopters and fighter jets.

By his own count, Robson has witnessed numerous aircraft tire maintenance procedures and has inspected hundreds of worn tires. He has seen firsthand the ill effects of improper maintenance. As a result, Robson can offer valuable advice for those who wish to better understand how proper aircraft tire maintenance can help to deliver more landings.

The most important factor of any aircraft tire maintenance program is maintaining proper inflation pressure. 
According to Robson, the problems created by incorrect inflation can be severe. Over inflation often leads to uneven tread wear and reduced traction, makes the tread more susceptible to cutting, and places greater stress on aircraft wheels. Under inflation creates faster tread wear on the shoulders, damages the tire’s innerliner, and greatly increases the stress and flex heating in the tire that can lead to tire failure.
 “Because aircraft tire/wheel assemblies can lose up to 5 percent of their pressure each day, they need to be checked daily, or before each flight, with a calibrated pressure gauge when the tire is at ambient temperature (not heated by taxiing). Any tire that’s been run more than 10 percent underinflated should be removed from service,” Robson said. The industry veteran also recommends filling tubeless assemblies with nitrogen instead of air because it’s dry and non-combustible.

Another key area of aircraft tire maintenance:
  • Lookout for no harmful chemicals are used or spilled on the tires. 
  • Keep hangar floors clean of all debris to avoid foreign object damage to the tires. 
  • It is also important to inspect the tires closely, in addition to checking tire pressure, during pre-flights to check for any damage to the tires from service.

History of Aviation: Leonardo da Vinci made the First Real Studies of Flight in the 1480's - The Ornithopter

1485 Leonardo da Vinci - The Ornithopter

Leonardo da Vinci made the first real studies of flight in the 1480's. He had over 100 drawings that illustrated his theories on flight.
Leonardo da Vinci's Ornithopter
The Ornithopter flying machine was never actually created. It was a design that Leonardo da Vinci created to show how man could fly. The modern day helicopter is based on this concept.

Early Efforts of Flight

Around 400 BC – China
The discovery of the kite that could fly in the air by the Chinese started humans thinking about flying. Kites were used by the Chinese in religious ceremonies. They built many colorful kites for fun, also. More sophisticated kites were used to test weather conditions. Kites have been important to the invention of flight as they were the forerunner to balloons and gliders.

Humans try to fly like birds
For many centuries, humans have tried to fly just like the birds. Wings made of feathers or light weight wood have been attached to arms to test their ability to fly. The results were often disastrous as the muscles of the human arms are not like a birds and can not move with the strength of a bird.

Hero and the Aeolipile
Aeolipile The ancient Greek engineer, Hero of Alexandria, worked with air pressure and steam to create sources of power. One experiment that he developed was the aeolipile which used jets of steam to create rotary motion.
Hero mounted a sphere on top of a water kettle. A fire below the kettle turned the water into steam, and the gas traveled through pipes to the sphere. Two L-shaped tubes on opposite sides of the sphere allowed the gas to escape, which gave a thrust to the sphere that caused it to rotate.

Joseph and Jacques Montgolfier- the First Hot Air Balloon -1783
The brothers, Joseph Michel and Jacques Etienne Montgolfier, were inventors of the first hot air balloon. They used the smoke from a fire to blow hot air into a silk bag. The silk bag was attached to a basket. The hot air then rose and allowed the balloon to be lighter-than-air.

In 1783, the first passengers in the colorful balloon were a sheep, rooster and duck. It climbed to a height of about 6,000 feet and traveled more than 1 mile. After this first success, the brothers began to send men up in balloons. The first manned flight was on November 21, 1783, the passengers were Jean-Francois Pilatre de Rozier and Francois Laurent.

George Cayley - 1799 - 1850's
Over 50 years he made improvements to the gliders. He changed the shape of the wings so that the air would flow over the wings correctly. He designed a tail for the gliders to help with the stability. He tried a biplane design to add strength to the glider. He also recognized that there would be a need for power if the flight was to be in the air for a long time.
George Cayley worked to discover a way that man could fly. He designed many different versions of gliders that used the movements of the body to control. A young boy, whose name is not known, was the first to fly one of his gliders.

19th And 20th Century Efforts
Otto Lilienthal 1891
German engineer, Otto Lilienthal, studied aerodynamics and worked to design a glider that would fly. He was the first person to design a glider that could fly a person and was able to fly long distances.

He was fascinated by the idea of flight. Based on his studies of birds and how they fly, he wrote a book on aerodynamics that was published in 1889 and this text was used by the Wright Brothers as the basis for their designs.After more than 2500 flights, he was killed when he lost control because of a sudden strong wind and crashed into the ground.

Samuel P. Langley 1891
Samuel Langley was an astronomer, who realized that power was needed to help man fly. He built a model of a plane, which he called an aerodrome, that included a steam-powered engine. In 1891, his model flew for 3/4s of a mile before running out of fuel.

Langley received a $50,000 grant to build a full sized aerodrome. It was too heavy to fly and it crashed. He was very disappointed. He gave up trying to fly. His major contributions to flight involved attempts at adding a power plant to a glider. He was also well known as the director of the Smithsonian Institute in Washington, DC

Orville and Wilbur Wright and the First Flight 1903
Orville and Wilbur Wright were very deliberate in their quest for flight. First, they spent many years learning about all the early developments of flight. They completed detailed research of what other early inventors had done. They read all the literature that was published up to that time. Then, they began to test the early theories with balloons and kites. They learned about how the wind would help with the flight and how it could affect the surfaces once up in the air.
The next step was to test the shapes of gliders much like George Cayley did when he was testing the many different shapes that would fly. They spent much time testing and learning about how gliders could be controlled.

They designed and used a wind tunnel to test the shapes of the wings and the tails of the gliders. After they found a glider shape that consistently would fly in the tests in the North Carolina Outer Banks dunes, then they turned their attention to how to create a propulsion system that would create the lift needed to fly.
The early engine that they used generated almost 12 horsepower.

The Wright Brother's Flyer
The "Flyer" lifted from level ground to the north of Big Kill Devil Hill, at 10:35 a.m., on December 17, 1903. Orville piloted the plane which weighed six hundred and five pounds..

Actual Flight of The Flyer at Kitty Hawk
The first heavier-than-air flight traveled one hundred twenty feet in twelve seconds. The two brothers took turns during the test flights. It was Orville's turn to test the plane, so he is the brother that is credited with the first flight.

Humankind was now able to fly! During the next century, many new airplanes and engines were developed to help transport people, luggage, cargo, military personnel and weapons. The 20th century's advances were all based on this first flight at Kitty Hawk by the American Brothers from Ohio.
