Diglykol not diglycol

German solid rocket fuel was not diglycol, which is a a marginally flammable oily liquid. It was diglykol, which is both one of the German names for diglycol, and also a deliberately misleading codename for a solid fuel made mainly from nitrocellulose and diethylene glycol dinitrate (which is manufactured by nitrating diglycol ...). The DEGDN serves as an energetic plasticiser for the NC; that is, it both converts the fibrous NC into a tough colloid that is suitable for use in a rocket, and (unlike some plasticisers, such as acetone) also contributes significant energy to the reaction. Nitroglycerine is also an energetic plasticiser for NC (mainly used in small arms propellants, and the obsolete explosive gelignite), but NG increases sensitivity to accidental functioning, whereas DEGDN reduces it.

Role of Rudolf Nebel?

Article claims:

The weapon was developed by Rheinmetall-Borsig under the leadership of Dipl.-Ing. Rudolf Nebel, who had pioneered German use of wing-mounted offensive rocketry in World War I with the Luftstreitkräfte.

However our biography article on Rudolf Nebel says that although he did pioneer airborne rocket weapons in WWI, he later opposed militarisation of rocketry, and was prevented from rocket work during WW2 because the SS regarded him as politically unsound.

It also says that the association of Rudolf Nebel with the various Nebelwerfers is incorrect, a frequent error based purely on the coincidence of names ("nebelwerfer" means "fog thrower" and is not an eponym.)

So -- is there are reference to say that Nebel had anything to do with this project? -- 202.63.39.58 (talk) 02:54, 22 January 2011 (UTC)

21cm Wurfgranate 42 or Werfer-Granate 21cm?

All the historical German documentation I can find, calls this weapon a Wurfgranate, not Werfer-granate. Also, it seems to be 21cm Wurfgranate 42. It would seem that the launcher is the (Nebel)werfer and the launched projectile is the Wurfgranate.?

21cm Wurfgranate 42 is the term for the projectile (the rocket) while the Fw 190 manuals call the launcher "21 cm BR" (BR = probably "Bordrakete") --Denniss (talk) 16:33, 20 September 2018 (UTC)
