It is the control planes on the submarine that are the primary method of normally controlling the rate of ascent or descent of the craft. Note that submarines have a few different configurations as regards planes. The stern planes are used alone, or in conjunction with the bow planes, if the boat is equiped with the latter ones, to change what is called "the bubble" or the angle of attack. On some boats, there are planes on what is called the fairwater or sail ("conning tower"), and these, the so-called fairwater planes, can be used to change depth slowly while maneuvering. It is these planes that are instrumental in maintaining depth on a properly trimmed boat as they are centrally mounted, and act to push the "whole boat" down or up without changing the bubble. Ballast tanks are flooded completely to dive and to conduct subsurface operations. The bouyancy of the boat (along with the trim) is controlled by the partially flooding the trim tanks.

What is the parachute valve at the top of a hot air balloon is used for?
The parachute valve at the top of a hot air balloon is used to release hot air from the envelope to control the descent rate. By opening the parachute valve, the pilot can allow hot air to escape, which cools the air inside the balloon and causes it to descend. This helps in maneuvering and landing the balloon safely.
What factors affect the rate at which a rotocopter falls?
The rate at which a rotocopter falls is influenced by several factors, including its weight, the design and efficiency of its rotor blades, and the angle of descent. Environmental conditions, such as wind speed and direction, also play a crucial role, as they can either hinder or aid the rotocopter's descent. Additionally, the pilot's control inputs, such as adjusting the rotor pitch, can significantly affect the descent rate. Lastly, the overall aerodynamic stability and drag characteristics of the rotocopter impact its falling rate.
What is an ascent rate for scuba diving?
no more than 18 meters per minute
What is the best shape for a parachute to ensure optimal performance and safety during descent?
The best shape for a parachute to ensure optimal performance and safety during descent is typically a round or elliptical shape. These shapes provide stability, control, and a slower descent rate, which helps to reduce the impact force when landing.
A hot air ballon begins its descent at a rate of 22 1 2 feet per minute how long will it take for the ballons elevation to change by -901 feet what is its rate of descent?
It is approx 40 minutes and 3 seconds. The rate of descent is 22.5 feet per minute!
Do things sink at the same rate in H2O?
No, their rate of descent depends on their "negative bouyancy"...
A hot air balloon descended 99.6 meters in 12 seconds what was the balloons average rate of descent in meters per second?
"Rate of descent" is a speed; so the idea is to divide the distance by the time.
How a parashute work?
A parachute works by creating drag as it opens and catches air. When a person or object is falling, the parachute slows down the descent by increasing air resistance, allowing for a safer and slower landing. The canopy shape and size help control the rate of descent and steer the parachute in a specific direction.
What is the variometer?
A variometer is a device that is used for indicating the rate of the aircraft's descent or climb.
What is the rate of climb and rate of descent of a passenger airplane?
Depending on the aircraft but most jets and passenger aircraft have a safe climb speed of anywhere between 1800 and 3000 feet per minute. A safe and sensible descent rate for the same aircraft may be between 800 and 2000 feet per minute.
Why does a person loss speed if he opens parachute?
When a person opens a parachute, it creates drag or air resistance which slows down the descent rate. The larger the parachute, the more drag is created, and the slower the person falls. This helps to reduce the speed and control the descent for a safe landing.
How do balloonists make the balloon descend gradually?
Balloonists can control the descent of a hot air balloon by releasing some hot air to cool the temperature inside the balloon. This decreases the buoyancy and allows the balloon to descend slowly. Additionally, the pilot can use different wind currents at different altitudes to control the descent rate.
