Hear this out loudPauseThe drag area of the parachute is calculated as Pi * D / 4, where D is the reference diameter. For flat sheet chutes like Top Flight, the reference diameter is the flattened diameter of the chute – again the diameter quoted by the manufacturer.
How many parachutes do I need for Duna?
Hear this out loudPauseOn Kerbin you need 1 regular chute for ~1.7t. If you have 8.. 12m/s engines on your bottom, you might be just fine with 1 chute for 2t. On Duna you need just the same.
What is the best size for a parachute?
Hear this out loudPauseExpert skydivers use parachutes that range in size from 80 square feet to 200 square feet. Newbies and expert divers use parachute sizes that are based on weight. However, some experts use parachutes that are small for their weight to gain a faster descent.
What is the best shape for a parachute?
Hear this out loudPauseThe 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.
Can I use parachutes on Duna?
Hear this out loudPauseParachutes work very well on Duna, though of not quite as well as Kerbin, so don’t rely on purely Kerbin testing – over design your Duna lander.
Can you use parachutes to land on Duna?
Hear this out loudPauseIn my experience (and mostly by feeling) 1 drogue and 1 regular parachutes is enough for a small lander (orbit->land->orbit) . The final burn seems to use less fuel weight than the weight of extra parachutes.
Does the size of the parachute matter?
Hear this out loudPauseWell, yes and no: what matters is the size, shape, and weight of the parachute. So if you have two parachutes with the same size and shape but made of different materials, one heavier than the other, the heavier parachute will fall faster. So a bigger parachute definitely falls slower than a smaller one.
How to calculate the size of a parachute?
For a given rocket mass give the required parachute size needed to achieve a specifed ground impact speed Rocket mass: kggOuncesPounds Type of Parachute: Parasheet (Cd = 0.75)Parachute (Cd = 1.5) Speed at which rocket to impact ground (in m/s): 3.02.52.01.51.00.5
How many XL class parachutes per 4 tonnes?
Total # XL class Parachutes = 1/4 Landing Mass; 1 parachute per 4 tonnes. The drogue parachute counts as an XL class for 4 tonnes but you should not use more than 2 of them for any size ship and never for more than 20% of tonnage of ship. You do not need drogue parachute on ships less than 50 tonnes.
How many parachutes do you need for a test landing?
It usually takes a few test landings to find the right amount of parachutes, but after that you should have a good feel for how many are needed. Just remember that more is better than less with parachutes, so don’t be afraid to stick four radials on your return craft.
What is the descent rate of a spherachute parachute?
For example, a Spherachute 120″ parachute has an equivalent diameter if 76.4 inches. However, the Cd of the Spherachute parachute is set to 1.5 so the resulting descent rate matches the manufacturers data. For these chutes the Cd is adjusted so the resulting descent rate matches the manufacturer’s published rates for that model.
