Only nine days after the specification was issued by the RLM (July 24, 1944), the first Me P.1101 had taken shape on paper.

Don't confuse the date Mtt got the contract from the RLM to start the prototype with the date the design was started.

The concept was completed long before the RLM issued their specification and awarded the money to Mtt to build it.

Dr Voigt tested the patent in a wind tunnel and in July 1942, Voigt and his team started designing such an aircraft,known as Project P 1101, backed by Messerschmitt.

the work on the P 1101 proceeded very slowly, until 1944, when the Oberkommando der Luftwaffe issued a requirement for a single-seat, single engine, turbojet fighter with a higher speed than the Me 262. Messerschmitt entered the P 1101 design and got the contract.

Really?

I would have to see the documents they refer too.

J. Richard Smith is undisputedly one of the world's foremost authorities on the history of the Luftwaffe. His works include the landmark publication Jet Planes of the Third Reich as well as Arado 234 Blitz, Luftwaffe Camouflage & Markings 1935-45, Me262, and numerous other leading aviation titles.

A qualified architect, Eddie J. Creek has for many years worked in partnership with Richard Smith producing a wealth of the most historically accurate line drawings and color artwork so far published on aviation in the Third Reich. As a historian and enthusiast, he has been actively collecting documents and photographs relative to the history of the Luftwaffe for over 30 years.

Niether one are engineers and most of the Luftwaffe was not either. Many times I have come across Luftwaffe documents with an erroneous explaination for engineering decisions.

The use of MW-50 in the BMW801 is filled with this to include memo's being issued to use a system the RLM technical office has to retract and clarify.

The fact remains that Mtt was heavilly involved by July 1942 in swept wing research and had gained experience flying swept wing designs.

It is a fact that in order to increase longitudinal control when mach tuck is encounted, you can move the forward CG to regain control power.

Swept wing research had been going on 8 years in Germany by the time July 1942 rolled around. In 1940, the LFA was sharing their research with industry leaders, including Mtt.

Since 1936 Busemann continued his scientific work at LFA on high speed aerodynamics and gasdynamics, and the beneficial effects of wingsweep on stability and control, and since 1937 he was in close contact about this subject with A. Betz of the AVA in Goettingen yielding a common
patent on the idea of sweepback for reducing drag and improving flight control issues at high subsonic speeds. In 1938 he again advocated the potential of wing sweep in order to maintain at least partially the favorable aerodynamic and flight mechanic properties of wings at lower speeds [16]. Since 1940 Busemann was visited by leading industrial aerodynamicists at LFA who picked up the idea of sweepback and initialized more wind tunnel data
bases at AVA, LFA and DVL.

In fact, Mtt developed the concept, applied for, and recieved the patent for a variable geometry swept wing in 1941.

Lippisch’s conception of both the variable sweep wing (Fig. 13, 14) for which Messerschmitt was granted a (then secret) patent in 1941. This led to the design of the Messerschmitt P.1101

Germans did not fully understand swept wing theory..

Mtt certainly understood the benefits enough during the design testing of the Me-262 to both modify the existing aircraft to add 18 degrees of sweep to increase the transonic flight envelope and to complete redesign the aircraft for later variants by adding 45 degrees of sweep.

Fact is they changed the wing from a straight wing to swept. I suspect they initially kept the center section straight to avoid the stability and control issues of a swept wing with nacelles.

It is simply not factual to argue that Mtt was unaware of the benefits of a swept wing and only "accidentaly" added wing sweep.
