What does GRS stand for in F1?
I think you mean DRS, Drag reduction system. Please see the related link.
Why paper width reduces with zero rush drag ratio?
Because the fibers are aligned in the MD direction and consequently the sheet shrinks in the CD direction, resulting in a reduction in sheet width.
What does the term drag mean in flight?
Drag is one of the four forces applicable to a flying aircraft: thrust, drag, lift and weight. Drag is the amount of resistance to forward motion caused by a solid body moving through a fluid (air is considered a fluid for the purpose of aerodynamics). The easiest way to feel the effect of drag is to stick one's arm out a car window while it's moving. First do it palm-down (horizontal), and then palm-forward (vertical). The force, known as "drag", pushing the arm backward increases substantially when the palm is vertical. That force is the same effect that an aircraft in flight experiences due to the frontal area of its airframe forcing its way through the air. The science of aerodynamics seeks to minimize the drag through streamlining and other design factors, since drag wastes fuel, but it is physically impossible to elimnate it.
How can we make website using HTML on Punjabi culture?
You should have knowledge of HTMLOr, you can use software where you'll need to drag and drop--you won't have to write HTML in this case.You need to have data on the Punjabi culture.For more information see the "Related Links"
How do you make a block movable using javascript?
search google for 'drag and drop script' OR go and download script.aculo.us, and implement the great drag and drop scripts they have.
How does the length of the wingspan of a rubber engine airplane affect the airborne time of the rubber engine airplane?
There is a component of the total drag of an aircraft called induced drag that depends inversely on the aspect ratio. The length of the wingspan is a key element in calculating aspect ratio. Aspect ratio is defined as the square of the wingspan divided by the wing area. The higher the aspect ratio of the wing, the less induced drag it creates and a slightly higher lift is generated than a shorter aspect ratio wing. In other words, long narrow wings fly easier than short stubby wings, and they stay aloft longer, all other elements being equal. That's one reason commercial jetliners (and the albatross) have such long wings compared to jet fighters (and hawks). That's also how the wingspan of the theoretical rubber engine airplane affects the airborne time of the plane. For an article on aspect ratio from NASA, and a neat little JAVA toy that lets you play with wing parameters, click the link below.
Why is induced drag aslo called lift drag?
Induced drag is the name given to the force of drag 'induced' by the act of increasing lift. Induced drag is directly related to how much lift the wing is producing, and usually angle of attack induced drag is usually caused by flow separations at high angles of attack and wing tip vortices, which is the main form of induced drag. Delta wings have massive induced drag because of their high chord which presents a high frontal area at high angles and leading edge vortices used to produce lift at low speed which generate lots of drag. At high speed and low angle however, the leading edge vortex no longer occurs and the wing has a very low frontal area which decreases the induced drag to almost nothing. Unlike other forms of drag, induced drag actually decreases with higher speed.
What is the aspect ratio of a high speed airplane?
Low! To minimize the drag which grow with the square of the speed.
Induced drag in airplane is reduced by?
winglet
What is zero lift coefficient of drag?
For no lift, The induced drag will be zero. However, there will still be drag due to viscous forces and pressure forces.
How can you maximize the lift to drag ratio of an aircraft?
Fly the airplane at L/Dmax speed. This is also know as best glide. This speed is found in the POH and represents where induced and parasite drags are at there minimal values for the airplane.
Why are aeroplanes shaped the way they are?
To produce lift with the least amount of induced drag.
Why drag increases as lift increase - for helis?
The production of lift creates induced drag. To create more lift, more airspeed is needed, and with airspeed, comes drag.
Why is maximizing the ratio of lift to drag forces desirable?
engineers generally want a Lift to Drag ratio to maximize the distance which an aircraft can fly.
What does drag mean?
Drag coefficient can be defined as the ratio of the drag on a body moving through air to the prioduct of the velocity and the surface area of the body.
What is the purpose of winglets?
Winglets increase an aircraft's operating efficiency by reducing induced drag at the tips of the wings
What is the importance of lift to drag ratio?
In aircraft aerodynamics, the lift-to-drag ratio, or L/D ratio, is the amount of lift generated by an aerofoil, divided by the drag it creates by moving through the air. A higher or more favourable L/D ratio is typically one of the major goals in aircraft design; since a particular aircraft's required lift is set by its weight, delivering that lift with lower drag leads directly to better fuel economy, climb performance, and glide ratio.
