How to convert thrust to horsepower? more
Measure the total thrust in pounds of force. here
Calculate the horsepower using the equation above.
Re: Pounds thrust to HP conversion here
My advice would be to go with no less than a 3.3 hp. It will give you considerably more power than your 55# electric AND alow you to get into a motor that has at least F& N gears if not F_N_R. This is a biggie IMHO. [links]
OK, thank you, that is really what I needed to know! here
The trolling motor has been very dependable over the past 2 years getting the 400' up the channel to my island cottage. Last weekend, 25MPH winds made it impossible for me to get back up wind and I was forced to spend an extra night out there and that got me to thinking that maybe I should use a small outboard instead. After playing with some of the old smaller ones I somehow accumulated while getting my 18HP for the pontoon running, I think they are as light to carry around as the trolling motor and battery are. more

7. Do engines lose horsepower over time?
1. Do electric cars have engine CC? more
4. Can you increase engine horsepower? [links]
5. How is engine horsepower measured? [links]
While CC and HP are related, they are not the same.
Increasing an engine horsepower, without changing the design of the engine itself, can be done through small improvements like changing the fuel type or exhaust outlet. [links]
Thrust and power ratings are probably done at a standard altitude and
velocity. The two are not constant and depend on many variable. But the
instantaneous power of an engine is basically the thrust it produces
multiplied by the planes air speed.
Dimensional analysis. In what units (M,L,T etc) are the
two quantities expressed? more
It doesn't. Apples aren't oranges. Horsepower is "power" - energy times
time. Thrust is force - energy per unit distance. Given a good hydraulic
jack I could generate 17000 pounds of thrust with my personal 1/4 horsepower
body. Just don't expect it *fast*. [links]
I think what he is talking about is this constant force from each
of 8 engines, sustained at some constant velocity and altitude
(cruising conditions). This would be force X distance/time, and
would equate to power. The choice of units could give an answer
in hp. 33,000 foot pounds per minute is one hp. [links]
Now, increase the speed to 36,900 feet per minute (450 mph) and
you get 147,600 hp equivalent. unless I miss keyed my
calculator.
The revelation that Germany *was* working on a long-range heavy bomber that
*could* have reached NYC from Berlin caused a lot of sweaty American palms,
however:
