EAS number indicates what speed the aircraft has to fly REALLY to stay airborne..TAS tells how fast you really are going.

IAS is indicated airspeed and it has to be always above EAS number at high.

Business jets have to have an IAS 165 KTS and this craft above only 35 KTS.

That is a huge advantage in going high..as is the rocket power.

For instance Space Ship 1 IAS was just 30 kts ( at the end of the rocket flight )....it longer flew...the rocket just pushed it higher.

That has nothing to do with what I asked.

Here is neatly summarized what Semmelewis Reflex means;

In Wilson's book The Game of Life, Timothy Leary provided the following polemical definition of the Semmelweis reflex: "Mob behavior found among primates and larval hominids on undeveloped planets, in which a discovery of important scientific fact is punished".

That doesn't have anything to do with what he asked either.

I will not present any calculations on a public site. These are all strict trade sectrets.


What you need to know is that the ( dynamic ) pressure is same as in low speed at 50 km/h speed so the heating does not occur...in any stage of the ascent or decent to space.


https://en.wikipedia.org/wiki/Stokes%27s_law


Some change occur but nothing that is cause for an alarm.


I will not talk no longer here....have a good life !

Sorry for interrupting again !

What is the fan design here ?

Here is the present system....7 billion USD to get the 6 astronauts to Mars with 3 ships.

Needs 3 x lift with Falcon Heavy to get all the reloadable fuel to orbit and other stuff like food.

Planes is a tad bigger than Solar Impulse but both developed 14 x as much solar power as SI I uses at high to obtain level flight.

In addition the bigger has 20 000 kg of batteries ...li-ion.

Mach 3 is gained by a dive from 42 kg...and using Oberth Effect some M 3.2 is gained eventually.

This maneuvre will save 10-15 % in rocket fuel when all this is done in very thin air.

Heavier ship can thus be lifted to LEO for the reload by Falcon Heavies before Mars trip.



Getting above the heating layer at sub sonic speed is the key for cheap space travel. In both directions...shuttle heated in 50-80 km in re-entry...and this pushes the slow down in to region 80-120 km where shuttle started to interact with atmosphere...aerodynamically...naturally as it is 25 x lighter...plane than any other system....the hypersonic speeds at relatively high speed in "extremely loose" air becomes sorta normal flying at very low wing loading before the heating starts.

The Baumgartner experience shows that a "craft" slow enough...no longer faces the feared compression in the thinner and thinner air above us. When nearing space.

Only F=ma and drag and lift equation prevail....with known supersonic aerodynamics of course....with "Baumgartner experience" in mind. How can I put it better...no compression but still not quite like at subsonic speeds...new thing to ponder I guess.

Navier Stokes and other "low level" aerodynamics sorta loose the touch in this..possibly..as it flies more or less in a mush ( deep stall )...but controlled still...above 120 km that is. Also the fact that heating starts in 80 km at M25 tells us a lot about the phenomena..of flying in thin air. In space nothing heats up...until at relativistic speeds. 80-300 km is something in between...space and known aerodynamics. This needs sorta brain capacity to model it out.

Any comments on above mentioned space flying concept..that will save us billions in space travel in the near future...which was introduced by von Braun as early 1948...just after Yaeger punched a hole in the sky !
