Mach and Altitude Sims

Apogee also sells software called "Splash"

best fun would be if it did, and could get the real-time NOAA data and use it!

RockSim 6x allows for 2d flight with wind. There is at least one layer of wind shear specified by the user. The altitude is most certainly affected by the wind.

Rocksim 7x allows for variable wind and thermals (still 2d). I am not sure about multiple shear layers, though.

remove Bart's phrase to reply

No, I don't think it does... not to disparage them. Pretty decent software.

Yup! couldn't agree more!

Just imagine being able to actually catch your rocket after a 30K plus ride because you were able to properly plan your flight! ;)

I would be interested... I've estimated the high-end temperature could reach

But where would you fly one of "my" motors?

The highest altitude flight I have ever seen caught was 8000 feet AGL.

Jerry

I doubt it. Dual deployment is a miracle.

Impressive... but I think you can fly them just about anywhere there is a decent patch of 'public' or 'government' land.

I think the FAA waiver ceiling for amatuer rockets is about 100,000 feet... above that, you enter the realm of the 'professional'... then it's a whole new tangle of red tape and massive fees. ;)

Good advice... I'll give it a shot... it's time I spent the money and upgraded anyway.

Do you know how it handles rockets once they reach +Mach speed?

There seems to be a problem there in version 6...

Truly... and it's a miracle that one can actually believe in! ;)

All the more reason to DIY instead of using a canned program. While it is not hard, it will take some time, especialy if this your rocket simulation program. Rocsim is good for the masses, but writing your own has merit as well.

just out of curiosity, what are the current records for HPR altitude and mach speed? or what with current engines what is possible? shockie B)

Hmmm... the more I think about this, the more I agree with you. In fact, most of it could be done quite easily in Excel.
