00X/004 future nuclear CATOBAR carrier thread

[JimmyMcFoob]

After doing some calculations, I can say most of you are wrong and I am correct. If you think adding more than 5 kts of speed from rest, or adding 0.3 kts of speed from 30kts max speed (30.3 kts total) is "insignificant", then idk what else to say. Those are relatively significant numbers.

Assumptions:
- 2 x F35 engine at balcony with afterburners: ~43,000 lbf x2 = 86,000 lbf (382 kN). (Could have easily add more Jet engines given the huge space of the balcony)
- Ford class carrier, mass: ~100,000 long tons ≈ 1 x 10^8 kg
- carrier drag force at 30kts, with 190 MW carrier propulsion: ~12.3 million N
- F35 engines are mounted and thrusting in line with the ship's longitudinal axis

Senario	Initial Accerelation	Long term speed gain/ Terminal speed
Starting from rest (Ideal, no drag)	~0.00382 m/s²	~13.7 m/s (~27 knots) after 1 hr
Starting from rest (realistic, with drag)	~0.00382 m/s², Non-linear, last ~6 minutes	~2.7 m/s (~ 5.3 knots), Terminal speed
Already at 30 Knots (Ideal, no drag)	~0.00382 m/s²	~ +13.7 m/s (~+ 27 knots)
Already at 30 knots (realistic, with drag)	~0.00382 m/s², Non-linear, last ~40 seconds	Added ~ 5.9 MW of power, translating to ~ + 0.3 kts (30 → 30.3 kts), Terminal speed

Bro here thinks he knows more than a man who has actually served on a carrier.

Bp Popeye is a retired ex-US navy serviceman served on US Navy aircraft carrier, he knows better. He posted a lot on aircraft carrier thread for the last 2 decades on this forum.

Well with all due respect, what role he served as on the boat is a huge factor on his boating knowledge.




BTW, what the hell is that umbrella doing there covering the engine intake?

thats appeal to authority fallacy buddy


p.s. why am I still a "new member" after so long, IMO I should be a LCDR by now. Waiting 5 minutes to post a comment is exhausting.

This is absolutely ridiculous and has absolutely no bearing in reality. The engine testing balcony is for engine testing and nothing else. Tomboy is absolutely correct.

Well, this was just a theory that it would work, of course no one takes such a drive seriously. Even though 100 years ago such experiments were done with rocket engines, in Germany and even in my country, a certain Mr. Otčenášek, an employee of the BATA company. Then in the fifties with jet engines, in the USSR and elsewhere, but I don't remember the details anymore.
So take it as not a suggestion, just a pun. You know, I'm not that ..ehmmm.. yet. Even though I'm 77 years old

Connecting one WS 10 engine means about 10 tons of thrust or the equivalent of about 30 to 40 thousand horsepower. Which is not exactly a small amount.
This power estimate is only a very rough one, it is based on the power of turbines that are created on the basis of aircraft engines.

You know, Top Gear The Grand Tour actually tested this, mounting a jet engine on a boat.

It did not work very well.

You know, guys, the "ignore" button on any user makes this forum a lot more productive and bullshit-free. It takes two seconds to banish someone from your feed and not have to see their "opinions" anymore.

Yes, those are definitely two blobs of white-ish color.

Enhance! I joke, but seriously, do you see something in particular?

You can observe a noticeable difference in width between the port and starboard sides. While this doesn't necessarily mean anything at this point, it's a detail worth noting.
