BAe Sea Harrier - Technical data and discussion

Before you started this whole argument about vectors, he was arguing that FeetPics clearly didn’t understand the provided materials at all, just randomly picked two parameters, and started comparing apples to oranges. At least that’s how I understood it.

now they are arguing that if a harrier has its nozzle pointed down 60 degrees relative to the 90 degrees

that it will accelerate equally forwards and upwards

anyone would look at that and go no its more up then forwards

This is basic trig. it’s the first thing you learn in trigonometry class.

It’s not linear. if you start with 20k thrust and angle at 45 deg you get about 14,140 for each vector. the total thrust DOES NOT become 28,280. the total is still 20k. you can’t just go a+b on the results because it’s not one dimensional, it’s not linear.

the only one who has been saying that has been you

feet pics said that

that is where it all started

at 60 degrees of nozzle angle you do not get equal parts net thrust both up and backwards

except he didnt

the important part is:

HORIZONTAL COMPONENT

lmao

IE the part pointing backwards he thinks is 50% of the total amount

No one, literally no one has said this. The quotes you have shown has not said this.

Wait, that’s not how it works.

think

nozzle are pointing more down then backwards the plane will go up more then forwards

of the total unvectored thrust

and guess what 10lbs is half of 20k lbs

which is the horizontal comonent at 60°

Im glad you are all not

A. structural engineers or you have strengthened the wrong side of a load baring structure

or

B. Harrier pilots you’d have all crashed

whats the horizontal component here procentual to the ammount of force?

this diagram puts the overall thrust at 33,500 lbs

thats literally more that the total thrust used in feet pics calc buddy (28,000)

bruh

ok you probably failed math

What do you think if the nozzle is pointing more down then backwards

Will half of the entire thrust point backwards?

#feetpics fans math

If you mount to the Harrier a fixed lift engine with 24,200 lbs, perpendicular to it, and a fixed engine with 14,000 lbs, their resultant thrust would be the same 28,000 lbs. That’s analogous to the Pegasus with its nozzles at 60 deg.
