What the f**k dose that got to do with my post ?

Heard a dog barking from across the street one day, never heard a bark like it, f****n hell it was standing about 7 foot tall on hind legs a big Kangal in a tiny little path and there was a pup sitting under it, that looked like some sort of Caucasian Shepherd big lump

New pics apparently from nasa from a satellite orbiting the sun of earth an dark side of the moon lol an the satellite is a million miles away from the earth an moon apparently. No wonder people speculate,can anyone notice what's up with this pic Google Image Result for https://preview.redd.it/the-moon-passed-between-nasas-deep-space-climate-v0-2usvralbfa4e1.jpeg?auto=webp&s=7371577aaeeb30f7daea8d918b1939454222f170 IMAGES.APP.GOO.GL

Worked down there for 6 months, around 18 years back, place called Rhymney, we was lodging in Princetown in the pub.

Read the f***ing post

Mother is small lurcher with a bit of collie, father is bigger lurcher apparently with a bit if saluki. Fairly mixed bag by all accounts

Look at the comparison in size of the earth to the sun,the sun looks a scary place

come on chart you don’t have to be a plane mechanic to know why they wouldnt use diesel lol not weight something called waxing the weight increase is like you say from higher compression hotter running temps needing more substantial materials now do you talking threw 3 stage rocket lol

Interesting about the fuel . My dad worked at Spadeadam in Cumbria where the Blue Streak rocket was being developed. He was just a maintenance man, not actually involved in the rocket. Anyhow, the Blue Streak was intended as a return strike ICBM in case of a Soviet nuclear strike. Problem was it was fueled by a mixture of kerosene and liquid oxygen. The kerosene was onboard but the liquid oxygen could only be added at the last minute to prevent it from freezing . It took about five minutes to add it to the kerosene in the fuel tanks, and in the event of a Soviet nuclear strike the

I’m gonna pick this up another day. I’m already side delving into the escape velocity equations lol Vinfinity2 = V2 - Ve2 and that’s just if you wanna visit Mars not get from Peckham to Paris

Yes basically the more mass you have to push the more energy it needs, hence bigger fuel tanks or air to air refuelling before going to space, the problem with rockets is the fuel, solid once lit has to fully burn out and a liquid can be very unstable for everyday use, i suppose the problems and solutions will be made at design level before anything ever takes off, look at rapulsine engines or liquid mercury which the nazis weee experimenting with during ww2

I would say because a diesel engine is , because of the much higher compression needed for ignition, far heavier than a petrol engine of similar power. Cheers.

I’m 5mins in on looking at this SABRE and it’s doing my brain in lol Mach 5 is around 9-10k km/h you need 11-12k km/h to reach escape velocity (I think the Saturns were hitting 13+k km/h). So that final push when it switches to rocket is what will give it the extra oomf to reach low orbit. It’s still carrying a fuuckton of fuel though. So weight, thrust, parabolic trajectory, distance will still be the same as conventional? Or am I wrong?

Also why has nobody tried using a small turbo diesel engine in home built light air craft that would power drone style propulsion where it dont need wings, surely it would be lighter than batteries with a much bigger range if it only powers electric motors

Same technology, the inlet air control, used on aircraft jet engines. Cheers.

Above i meant a rotating detonating engine not a pulse jet as such like the doodle bug ran on

I haven't even looked at inputs vs outputs tbvh but I should start tracking them.. I have been experimenting with a breeding experiment for colour for a while and it didn't yield the result I aimed for but it did give me some unusual colours.. lilac for instance and I have only just got the size back to something decent after 4 generations

The nose cones used to slide back and forth, yes it slowed down the air to subsonic so that the engine worked efficent, also the fuel it ran on had to be invented too

Would the moveable nose cone be a VIVG , ( Variable Inlet Vane Guide ) used basically to control the speed of the air entering the engine compared to the actual air speed . We overhauled these in house using calibration equipment to simulate flight conditions. Cheers.

Aye I’ve seen these before but not looked into or followed the tech…. That’s me going to sleep in 5 hours then

Where’s location

For the hypersonics to work efficently and reliably we would need to be able to create a protective plasma around the craft which behaves differently to the air around it, meaning keeps the outer skin of the craft cool enough to stay safe, this is a very interesting topic now, the sr71 had a moving nose cone on the fro t of the engines that slowed down the air enough from supersonic to sub sonic sp the engines worked correctly, they have tried pulse detonation engines but they are too unstable and keep going out of rhythm, id say they have the tech but not for civi use, i mean look at the blac

I’ll take a look mate thanks
