- In the Popular Rotorcraft Association, “rotorcraft” includes anything that uses rotor blades to produce the lift needed to fly, such as helicopters and gyroplanes. A “rotorcraft” is a specific US FAA “category” of aircraft. “Helicopters” and “Gyroplanes” are specific U.S. FAA “classes” of rotorcraft.

Seaplane A seaplane is a powered fixed-wing aircraft capable of taking off and landing on water. Seaplanes that can also take off and land on airfields are in a subclass called amphibious aircraft. Seaplanes and amphibians are usually divided into two categories based on their technological characteristics: floatplanes and flying boats; the latter are generally far larger and can carry far more. These aircraft were sometimes called hydroplanes, but currently this term applies instead to motor-powered wat

Scramjet A scramjet (supersonic combusting ramjet) is a variant of a ramjet airbreathing jet engine in which combustion takes place in supersonic airflow.pace launch vehicles may or may not benefit from having a scramjet stage. A scramjet stage of a launch vehicle theoretically provides a specific impulse of 1000 to 4000 s whereas a rocket provides less than 450 s while in the atmosphere.

Helicopter parent A helicopter parent (also called a cosseting parent or simply a cosseter) is a parent who pays extremely close attention to a child's or children's experiences and problems, particularly at educational institutions.atie Roiphe, commenting on Levine's work in Slate elaborates on myths about helicopter parenting: [I]t is about too much presence, but it's also about the wrong kind of presence. In fact, it can be reasonably read by children as absence, as not caring about what is really going on with them ...

Helicopter A helicopter is a type of rotorcraft in which lift and thrust are supplied by rotors. This allows the helicopter to take off and land vertically, to hover, and to fly forward, backward, and laterally.

Helicopters Helicopters also make air move over airfoils to generate lift, but instead of having their airfoils in a single fixed wing, they have them built into their rotor blades, which spin around at high speed (roughly 500 RPM, revolutions per minute).

Roll, pitch and yaw Roll, pitch and yaw. Roll, pitch and yaw are rotations along the natural axes of the helicopter (or any aircraft). A rolling movement is where the helicopter rotates along a line along its length using lateral cyclic inputs (aileron), eventually turning from right way up to inverted while maintaining the helicopter's heading.

Hydroplane (boat) Hydroplane (boat) A hydroplane (or hydro, or thunderboat) is a fast motorboat, where the hull shape is such that at speed, the weight of the boat is supported by planing forces, rather than simple buoyancy. A key aspect of hydroplanes is that they use the water they are on for lift rather than buoyancy, as well as for propulsion and steering: when travelling at high speed water is forced downwards by the bottom of the boat's hull.

Brake Rotors/Discs Replacement Service & Cost A brake rotor is a smooth metal disc attached to the wheel hub. Most new cars (1999 and above) come with rotors at each wheel. Older cars may have drums instead of rotors at the rear wheels. Brake rotors play an important part in the braking system. It is the friction between brake pads and rotors that cause your car to slow down and stop.

Fan (machine) A household electric floor fan. A fan is a machine used to create flow within a fluid, typically a gas such as air. The fan consists of a rotating arrangement of vanes or blades which act on the fluid. The rotating assembly of blades and hub is known as an impeller, a rotor, or a runner. Usually, it is contained within some form of housing or case.

- From the time your chicks hatch until 6 weeks of age you will need to feed them chick starter mash with a protein level of 20 percent. It is important that you feed your baby chicks different food to your laying hens as the extra calcium that the older birds need for laying eggs is actually detrimental to baby chicks.rom the time your chicks hatch until 6 weeks of age you will need to feed them chick starter mash with a protein level of 20 percent.

IRS to Delay Tax Refunds Involving EITC and ACTC Next Year Under the new law, the IRS cannot release the part of the refund that is not associated with the EITC and ACTC. Taxpayers should file as they normally do, and tax return preparers should also submit returns as they normally do. The IRS will begin accepting and processing tax returns once the filing season begins, as we do every year.

Helicopter Rig A helicopter rig is a rig that comes in especially handy when fishing to open water marks and when fishing to far banks, islands and lily pads, especially over lake bottoms of sand and gravel. When using a helicopter rig, the weight of the lead is able to be rapidly transferred to the point of the hook.Typically a 12 lb fluorocarbon mainline is used with 30 lb low profile leaders and semi tight clutches and not bait runners.hen using a helicopter rig, the weight of the lead is able to be rapidly transferred to the point of the hook.

- A hovercraft is one of the children of the air cushion vehicle (ACV) family that flies above the earth's surface on a cushion of air. It is powered by an engine that provides both the lift cushion and the thrust for forward or reverse movement.
