 Potential energy question ( aeroplane vs escalator ) ! Posted on: Thu Jan 11, 2018 10:33 amI have notissed that 450 kg weighing AQUILA glider ( FACEBOOK DRONE )cruises at 20-25 km altitude using only 5 kW of power on its engine....which power comes from the sun.
Power ratio is 0.011 kw/kg. If I lift 450 kg to 25 km..how much energy do I have to consume using an escalator ? Do I somehow avoid it using an solar powered aircraft..or is it still using same amount of ( free ) energy ??? _________________ http://mesoslaunch.blogspot.fi/ http://max3fan.blogspot.com/ |

Re: Potential energy question ( aeroplane vs escalator ) ! Posted on: Fri Jan 12, 2018 4:07 pm I have a question !
If I manage to haul a 80 metric ton spaceplane to 42 km altitude...and dive like Baumgartner and lit the rocket at 27 km..will it exceeed M3 if the starting speed is 980 km/h at 42 km in propeller configuration ???? If I then use the max rocket power ( Merlin D1 ) to escape from the earths gravity to LEO ( first ) ...how much Oberth Effect gives me as increased delta-V ???  _________________ http://mesoslaunch.blogspot.fi/ http://max3fan.blogspot.com/ |
