Ascent stage initial acceleration

[Allan F]

I have been conversing with a person, who claims the initial acceleration of the A17 ascent stage was about 3 times higher than expected from the numbers for mass, thrust and gravity.

I plugged the numbers for the ascent stage in, found an acceleration of

16kN, 2445 kg spacecraft plus 2376 kg ascent fuel, plus two astronauts, and a bag of samples about 250 kg.

This gives a= f/m -> a = 16.000 N / 5071 kg -> a = 3.155 m/s^2 minus lunar gravity of 1.62 m/s^2 ->1,535 m/^2

He claims his calculations, based on the TV-transmission from the LRV, gives an initial acceleration of 3.74 m/s^2. I have pointed out what I think is a flaw in his idea, namely the ascent engine firing into the descent stage, and some pressure between the two parts would give the ascent stage a significant push for the first fraction of a second.

Now he even claims A16's ascent stage DEcelerated after it launched.

I'd love if he could get his account approved, I think BK would benefit from some of the people's knowledge and experience here, rather than Rasa's FB group.

I have written LO to approve him.

That is exactly the information I was looking for. Had totally forgotten I was in that thread too.

I am here now, thank you for approving me.

I am going to start a new thread on this, so that it starts out on the right foot, without chatter about approving me, etc.  I'll present my proof/case, and the invite the waves of scrutiny.
