How does a Ljungstrom steam turbine work and look like?
Ljungstrom Turbine is a Radial Outflow Steam Turbine with two counter rotating discs. Blades are mounted in circles one bigger than the other. Blades of one rotor work as nozzles for the other rotor blades. This turbine design is very forgiving on wet steam. It is said that the turbine design had limitations on scaling up above 30 MW and hence could not compete with Axial Flow Turbines.
What do the blades of a wind turbine look like?
They look like propellers, or fans.
What does a wind turbine look like?
a wind turbine looks like a giant fan
What exactly does turbomachinery do?
The best way for one to understand what turbomachinery does is to look at a turbine. Turbomachinery is when machines transfer energy from a rotor to a fluid.
What do iris blades look like?
Iris blades close in a circle.
What does a wind look like?
a wind turbine looks like a giant fan
How does a helicopter fly?
A helicopter is able to fly because of the lifting effect of its main rotor. The rotor blades of a helicopter act in the same manner as the wings of a plane, creating lift by forcing air above and below a curved airfoil. The air moves faster over the top of the blade, reducing the pressure there. The air below pushes upward with greater pressure, lifting the rotor and the attached frame and cabin. At the same time, the blades can be angled in any direction, allowing it to move in any direction by using the blades like the propellers on an airplane. Jet helicopters also generate some forward speed from their turbine exhaust. The main rotor is the set of blades on the top of the craft, driven by the engine (piston, jet turbine, etc.). By turning the blades, which are airfoils and like a narrow "wing" in shape, we move them through the air. And by "tipping" the leading edge of the blade up (increasing the pitch) as it moves, the blade will have a positive angle of attack. It will bite into the air and force that air down. This forces the blades up, and the rotor will provide lift. Lift causes the craft to defy gravity. The torque (rotational motion) of a single rotor blade will have to be offset, and the tail rotor does this. Additionally, the tail rotor (or air turbine in the NOTAR helicopter) will also allow the craft to be turned and "pointed" in another direction. The pedals control the tail rotor or air turbine. By pushing the stick to the side (and adding a bit more pitch with the cyclic), the blades can be controlled to allow a bit more lift on one side to tip or bank the chopper and turn it. (A bit more pitch is added to offset the slight loss of lift.) The pedals will also be used in conjunction with the stick. By pushing the stick left, the blades will have a bit more pitch as they come around on the right side and a bit less as they come around on the left side. This will bank and turn the helicopter. Pushing the stick forward causes more pitch to the blades as they come around the back of the circle they make around the craft. This lifts the back of the craft. And it will make for a bit less pitch in the front for a bit less lift in front. This tips the craft forward. Often when we see a helicopter take off, it rises a bit, tips forward (now that the rotors will clear the ground), and accelerates forward as it continues to rise. The pilot has pulled up on the collective (to increase the pitch of the main rotor blades). That provided lift. He also has to push forward on the cyclic to tip the helicopter forward to begin to gather forward airspeed. (for more information see the related links below) A helicopter can take off and land vertically (straight up and down). It can fly in any direction, even sideways and backwards. It can also hover or hang in the air above a given place. A helicopter gets its power from rotors or blades. When its rotors are spinning, a helicopter doesn't look much like an airplane. But the rotor blades have an airfoil shape like the wings of an airplane. So as the rotors turn, air flows more quickly over the tops of the blades than it does below. This creates enough lift for flight. Additionally, helicopters avoid areas close to storms. The reason is that the helicopter requires a careful balance of the air supporting it. Downdrafts or turbulent winds can drastically affect control of the helicopter.
What is a gallade look like?
gallade looks like gardevour but it has this blades on its arm.
What does a bad rotor look like?
what do brakes look like when they go bad, how far can rotors go?
How do you make a one seat helicoptor?
look into a gyrocopter because a helecopter is to complicated. A helecopter needs a gearbox and cyclical controls which are complicated and difficult to produce. Also rotor blades and a tail rotor and shafts and bearings. Difficult to fly and dangerous
Why are the wind turbines today three bladed?
The number of blades involves design considerations of:-aerodynamic efficiencycomponent costssystem reliabilityand finally aestheticsOver the last 50 years wind turbines have almost universally used either two or three blades because while aerodynamic efficiency increases with number of blades, it does so with diminishing returns.Thus increasing the number of blades from one to two yields a six percent increase in aerodynamic efficiency, and increasing the blade count from two to three yields only an additional three percent in efficiency.This means that increasing above three yields minimal only improvements and put up the component costs of the turbine (the fewer the number of blades, the lower the material and manufacturing costs will be).In addition, the fewer the number of blades, the higher the rotational speed can be because blade stiffness requirements to avoid the blades bending to hit the tower limit how thin the blades can be. Higher rotational speeds reduce peak torques in the drive train, resulting in lower gearbox and generator costs.Also three blades give system reliability because cyclic loads, when combined together at the drive train shaft, are symmetrically balanced for three blades, yielding smoother operation during turbine yaw.Finally, aesthetics can be considered a factor, most people find that the three-bladed rotor is more pleasing to look at than a one- or two-bladed rotor.
What is a warped brake rotor?
A warped brake rotor is a rotor that's no longer flat. When viewed from the front or the rear, it'll no longer look like a straight line, but be a Little bit wavy.
