At what speed does a drag car need a parachute?
The Requirements NHRA and IHRA require any race car that goes over 150mph in the quarter-mile to have and use a parachute. If your car hits the 200mph mark in the quarter-mile, then you are required to run dual-chutes.
Do drag racers use parachutes?
Cars fitted with parachutes are commonly seen during legally-sanctioned drag races abroad; sometimes even locally. Often, these are used by cars capable of doing 8-second passes or reach a high top speed within the quarter mile. The cars need the parachute in order to slow it down after crossing the line.

What makes drag cars so fast?
The engine distributes power to the wheels in just 15/100ths of a second. Literally the blink of an eye. When they are accelerating, the drivers of Top Fuel dragsters feel G-forces that are comparable to an astronaut launching into space. These cars are so fast, traditional braking systems do little to slow them down.

If it fails, the skydiver can cut it away and deploy the reserve. There is the container, which is a backpack that holds the main chute and the reserve chute. There are the lines, which run from the parachute to the container through a pair of thick straps called the risers.
How much HP do drag cars have?

How much HP do funny cars have?
Horsepower claims vary widely—from 6,978 to 8,897—but are probably around 8,000 HP. Supercharged, nitromethane-fueled motors of this type also have a very high torque, which is estimated at 7,000 ft⋅lbf (9,500 N⋅m).

What type of parachute gives the most drag?
The circle parachute should demonstrate the slowest average descent rate because its natural symmetrical shape would be the most efficient design to maximize wind resistance and create drag.
How is drag calculated?
The drag equation states that drag D is equal to the drag coefficient Cd times the density r times half of the velocity V squared times the reference area A. For given air conditions, shape, and inclination of the object, we must determine a value for Cd to determine drag.
Are military parachutes steerable?
Designed, developed and manufactured by Airborne Systems, the T-11 is the next generation non-steerable troop parachute system. Airborne Systems is the only qualified source to provide the T-11 system internationally. The T-11 system includes the main canopy and harness and the T-11R reserve parachute.
