[Ask] How to change Me163_599 / Me163B cockpit?

Yep, she is fast, and is still fairly maneuverable at high speeds. I've had a great time working on the flight dynamics for this aircraft. I seriously question any source that claims it broke the sound barrier though. I watched an interview with Rudy Opitz, one of the chief test pilots, and also the pilot of the aircraft involved in the incident you described, and he denied speculation that his aircraft or any other Me 163 ever broke the sound barrier. It was, however, one of the first aircraft to enter the transonic flight regime, which it would reach at about Mach .84 and exhibit the nasty characteristic of a strong nose down pitch simultaneous with the controls becoming totally ineffective. The only way out was to throttle back or shut down (if the engine didn't quit on its own due to the negative g forces) before you became the world's fastest lawn dart.

The CFS3 Komet replicates this behavior, minus the negative g engine cutout. At higher altitudes you are more susceptible to this as the speed of sound is lower. You'll have to fly like the real pilots did and use all that excess thrust to climb and then dive back down at idle or once your fuel is exhausted.

I will be including a document that summarizes what I've learned about the Me 163 to give players a better idea of what an amazing and unique machine they are flying.

Andy, just had a closer look at that tail wheel picture and got a new clue for ground handling. I knew the Komet had a castoring tail wheel, but couldn't find out if there was a tail wheel lock. From the stencil painted above it, it seems there was, and it was set by the ground crew before takeoff. So for our purposes, the tail wheel will always be non castoring with no option to unlock it. Thanks!
 
You are right,Sir. I stand corrected on the account. My memory of the Military Channel show was scrambled.I have a book on WW2 jet and rocket aircraft,guess i need to reread it. Thanks for the information .
 
Oh no worries, I didn't know any of that stuff before I started doing the research for this project in the first place. Also, it's amazing how much bad information is out there, even from seemingly reputable sources. (I will resist the urge to go on a history channel rant here, military channel usually seems a bit better) I've gotten to where I don't believe much of what I read unless I can find a primary source, or at least see that one was referenced.
 
This is a beautiful model.As you stated the flight modeling will be accurate , which i play a sim in the first place for.Can't wait for it to be released. Thanks to all who is involved in this aircraft project and the mission project too.:very_drunk:
 
oh, yes, Mr. MajorMagee! Ive used your wheel disc (rim) photo as a new base paint for the Komet wheel skins.
is it ok for you? a four wheel skins are made now from this source, including the red and redwhite disc color version. I will post some shots later.

another nice news: I got permissions from Erwin Wiedmer (www.deutscheluftwaffe.de) to use his Me 163B instrument / panel photo for our Komet textures - so I will enhance the front panel texture a bit yet :)
 
ok, the "phantastic four" wheel skin set... see bottom :)

Thanks

Haven't been this excited since Sky Unlimited's P-51 Mustang was released! Unlike CFS3's GO-229 this aircraft saw action.I always thought the Me-163 should have been included in CFS3 originally. Excellent work O GREAT ONE!!! Keep us posted please and much thanks!!
 
oh, thanks for such kind of nice words :)

well, I still remember the Secret Weapons of the Luftwaffe gameplay euphory of and to be honest since this I always wanted to see Me 163B in any "real" flightsim.
there was a lot of Me 262 jets made for example, but up to Il-2 Sturmovik there was no flyable Komet made - meant at commercial scene, if I good remember. a bit later we got a flyable Komet with Wings Of Pray, and latestly we can fly this rocket birdy at World Of Airplanes. god thanks for that :)
aside this I am very happy of the Flight Replicas FSX Komet release - this small team took it bit more seriously, it seems and it looks like a good Komet stuff, I would say. no wonder it is a payware - it just looks perfect, I suppose :) here needs to say I dont have FSX sofar, so I cant test it.

our CFS3 Komet solution should be a simple alternative for all Komet fans and combat pilots, given public as freeware... :)


ok, here is latest cpit screenshot, presenting the bit enhanced front panel texture.

Nice! I think this model will rival any of those. The FSX one I think is the best, but I think we may be the first to have a properly working rocket motor in an MS sim and of course we can actually shoot things with it!:redfire:
 
June 10, 1945 Interrogation of Alexander Lippisch.

Lippisch indicated that the later stages of his development of flying wings were mostly related to the Me163 series. This airplane exists in three arrangements. The 163A had zero moment coefficient sections and obtained stability by washout. The 163B superseded this with a wing of nearly identical planform but with an airfoil with positive moment coefficient at the center. The tips were symmetrical and had 5.7 degree of aerodynamic washout. The leading edge was sweptback 29 degrees and a 40% span fixed slot was used. The wing of the 163C differed from that of the 163B primarily in that the twist was removed.

A fixed slot was used to prevent tip stalling with attendant bad rolling characteristics as well as longitudinal instability. Lippisch use fixed slots because he felt that the drag of a properly designed fixed slot was no greater than the actual drag of a moveable slot when manufacturing tolerances and flight deflections were considered. His fixed slots were designed to have low drag by connecting points of equal pressure. He estimated the local section drag was increased by 30% by the slot.

Lippisch said that the most serious stall problems were encountered upon recovery from turns. This was due to the use of down elevons at high lifts in this condition. This is not a steady state condition but a maneuvering condition.

The 163B airplane was rocket powered. It had 1500Kg thrust as weighed 4100Kg initially, 2100Kg of fuel were carried and all but 500Kg were consumed in the climb which took 3 minutes to reach 10000 meters. The remaining fuel was used for cruising and combat. Due to the inertia of rotating parts the engine required one minute to reach full power.

At high mach numbers a diving moment was obtained. The airplanes were placarded against exceeding M 0.75 by a Mach meter. Recovering from excessive speed could be made by cutting power. Wind tunnel experiments indicated critical stability Mach numbers of M 0.85 for 163B and M 0.92 for 163C.

A CG location of about 21% MAC was used. CG limits of 17 to 22% are normal. The elevons are specially designed. They have 26.3% of their area ahead of the hinge line and have a rounded nose. There is a large gap between the elevons and the wing and the wing ahead of the elevon is terminated in a radius. The elevons do not cause much instability due to upfloating. The leading edge slot which has an exit gap of 1.2% chord prevents serious upfloating near the stall.

Lippisch has done much work on lateral stability. Very little dihedral is used and roll due to yaw is kept as small as possible but still positive. Sufficient vertical tail is added to keep a conventional ratio of rolling moment due to yawing movement due to yaw. Lippisch desires to have a lateral center of pressure about 40% MAC aft of the CG. HE considers it necessary to use a vertical tail on tail-less airplanes. HE does not believe that these tails should be located on wing tips because of flutter problems and effects on the tip vortex on the rudders.

Lippisch has obtained a maximum value of lift of 1 – 1.25. The lift drag ratios of his airplanes are 163A 1:18, 163B 1:16, 163C not measured. These airplanes have an aspect ratio of 4.4.

Great find! If you come across anything else like that please let me know. I am strongly considering purchasing air wrench and rebuild the air with it and add in the pieces that are already set. But first there are a few other aspects of the project I need to focus on. But I am trying to gather useful aerodynamic info, which that article was chock full of, thanks!
 
WOW!!!! A lot of info. there ,MajorMagee ! Wish i had a book with that much detail. Have only one decent book that covers only jet and rocket fighters of WW2. What is the title of the book you have? It is my hope that the Me-163 project's flight model is as close as possible to the real thing. It's better to take your time and get it right,than rush on it. Amazing work on the Me-163!!!Looks very professional .So thankful for the time and research that has gone into the Me-163 project!!

well, I personally am owner of few books (translated into my mother tongue), written by real Komet pilots:

Rocket Fighter by Mano Ziegler
Top Secret Bird by Wolfgang Spate


there exists also a lot of monography books, which I have, like those:

Bojové legendy - Messerschmitt Me 163 Komet
Me 163 Komet (Monografie Lotnicze 35)


A great source of info is a Robs site about Komet, this is a References page


There is a nice documentary movie about Komet, the Me-163 Komet - Wings of the Luftwaffe
and few anothers like this one: Dr Reinhard Opitz - Me163 pilot
 
Thanks for the links,very useful. I loved the whole Wing series on the discovery/military channel too . The series is what sparked my interest in the Me-163 in the first place. Let's hope this project on the Me-163 will fly as great and accurately as it physically looks also.
