Eve Aerobraking and atmospheric entry

[gilflo]

Hi guys

For those who are interested on how to aerobrake and enter Eve atmosphere, here is my design to save DV on launching a plane to join my 2 Kerbals waiting in Evalander

 

Using now KSP 1.1.3

 

Retrograde mod to brake 50° before target, aiming a -150kms Peri

 

It's done

 

Now ASS on prograde for Entry

Here is the optimum design, ejectable deployable shield ahead, big tank  with speed brakes on back and small spare tank with a lot of Vernors for RCS at center, near the CG (when big tank nearly empty), so that they will be very helpful if we need them

 

The shield begins to heat under 80kms, mach near maximum

 

62 Kms, mach decreasing, temperature rising

 

44 kms, Mach under 7 and temperature decreasing. A flip would be no issue now

 

36 kms, still on prograde

 

25 kms, we begin to get out of prograde, but flip, mach and T° are no more a factor

 

Ejection of rear tank

 

ASS on OFF, spare tank ejected, CG ahead of CL the plane stabilize nose down

 

Playing with pitch I nose up and eject the shield

 

Now a real plane

 

Engine started we fly with FWB on atmospheric autopilot. (very good mod)

heading north to join the lakes that are east of our objective on the Scansat map

 

Take a look at Atmospheric autopilot.  As you cannot guess, great help to pilot without autopilot!!!

Going down fast to admire the lake

 

low altitude flight, fine controls, (blue indicators)

 

Now we are going to turn left to head west towards our objective

 

Beginning turn

 

with atmospheric AP, the altitude is very stable in manual...

 

gaining altitude to fly over land

 

9km from objective, 14 m from ground, 360 kts, no error is allowed!!

 

250m from objective, we can see Evalander and Jedediah, we pass under 50m

 

Nearer

 

Speed 300 kms, we see clearly the lander

 

after a 180 turn, new pass, then we will land

 

outbound, increasing altitude for the final turn

 

90° bank turn

 

Final 1 km

 

Nearly on ground

 

Speedbrake out

 

approaching Jedediah and the lander

 

Here we are
