If i wnat to lift/hover my self up 30ft off the groud (i am 110 pounds) how much HP would i need and how much would i need to lift/hover 300 pounds. Please answer TYSM
Yeah basicallyruss_watters said:Lift/hover with what? A quadcopter like thing? That's really dangerous.
Much safer to get a ride on one of these personal drone aircraft...sesefdfsd said:Yeah basically
Damn 1mil USD is a lot though if even i where to make this it would cost me 5 grand (which i don't have)anorlunda said:Here is a place that offers a $1 million dollar prize for anyone who can make that work safely.

Will you be electric or jet fuel powered? Frenchman Franky Zapata's Flyboard lifts ~200 lbs with 5 model jet engines. A rough back or the envelope calculation based on a 45 lb thrust engines each consuming 0.55 L/min with an energy density of 44.6 MJ/kg gives about 2500HP but probably 80% of that power is waste heat.sesefdfsd said:If i want to lift/hover myself up 30 ft off the ground (i am 110 pounds) how much HP would i need and how much would i need to lift/hover 300 pounds.

More power is no problem, keeping stability is.sesefdfsd said:I appreciate the help but that definatly can't lift 300 pounds let alone 20lb

i am build a drone i can stand onbob012345 said:Will you be electric or jet fuel powered? Frenchman Franky Zapata's Flyboard lifts ~200 lbs with 5 model jet engines.

The Jetson machine above quotes a max power of only 88kW which is ~100HP.

Please take the time to type out whole words; it will help your cause here a lot. Is "tr" = "tryn" = "trying"?sesefdfsd said:i am tr

Beyond that, what is your background in feedback and control theory? If you want to design a drone to lift you in flight, you will need a strong background in control theory (plus all the other stuff like aerodynamic propulsion)...
sesefdfsd said:ye, so i made this frame out of aluminum and now i need a motor that can lift 50 pounds (i would then buy a few to support my weight of 110lb)
I'm worried. @sesefdfsd this is a project that is dangerous and expensive to do correctly. To do it poorly is just dangerous. In between is extremely dangerous. For liability reasons we can't help you with this project, and I strongly suggest you abandon it.berkeman said:No worries.
Thrust is the force generated by a propulsion system, such as a helicopter's rotor blades, that enables it to move in a specific direction. In order to hover, the thrust generated must be equal to the weight of the object being lifted.
The amount of thrust needed to hover 300 pounds at 30' off the ground is affected by several factors, including the weight of the object, the altitude and air density, and the efficiency of the propulsion system.
The formula for calculating thrust is: thrust = mass x acceleration. In this case, the mass is 300 pounds and the acceleration is the force of gravity, which is 9.8 meters per second squared. Therefore, the thrust needed to hover 300 pounds at 30' off the ground would be approximately 2,940 newtons.
Horsepower is a unit of power that measures the rate at which work is done. In order to hover, a certain amount of thrust is needed, which is directly related to the amount of horsepower generated by the propulsion system. The more horsepower, the more thrust can be generated.
There are several ways to increase the amount of thrust and horsepower for hovering, such as using a more powerful engine, optimizing the design of the propulsion system, and reducing the weight of the object being lifted. However, it is important to consider safety and efficiency when making these modifications.
