Various Henschel projects

Hi! Excellent drawings.
I 'm not sure the meanig of these drawings but I imagine that Justo-san or Ed-san already know. Each radiator shape are different.

At least the color drawings that you posted are What-If material. When Logan was making these, I was sort of hoping that he would do a Heinkel He 100 with a DB 605 engine....

Something really puzzling/interesting is the linked Jumo 213. Junkers Motoren wasn`t very keen on these "gruppenmotoren" given Daimler-Benz`s bad experience. Nevertheless they toyed with this idea in the Jumo 212 (2xJumo 213) or the Jumo 215 (2xJumo 214), according Reinhard Müller`s "Junkers Flugtriebwerke".

I suppose the glittering prize for a successful linked engine was a lot of power for a relatively modest increase in drag. Calum would know better than I why they persisted with the idea so long. I actually asked Calum whether the British ever considered linking two Merlins - he said he would be surprised if it had never been suggested but there was no known evidence of it.

It was one of those ideas whose advantages were obvious and whose disadvantages less obvious. Once the He 177 was in production, there was no real alternative that didn' involve major modifications (and unacceptable delays). Not enough time to do it right, but plently of time to make never ending series of minor changes that, while overcoming some of the problems, never provided a fully satisfactory result. Then the DB "Power System" engines were even adopted for the Ju 288.

I will eventually. See below. The 28th and last one is my personal favourite - evidently Henschel designed the pressure cabin for the DFS 228 but regarded the rest of the 228 as "aerodynamically unrefined". It was therefore proposed to create a tailless altitude/speed record attempt aircraft by putting together a DFS 228 pressure cabin, P 135 wings and an all-new fuselage.
There are a handful of sketches (not original drawings) with the report but also a selection of photos, including one of a P 75 model that looks quite a lot different from the design depicted elsewhere.
I've attached the frontispiece, p2 (to give you an idea of the layout) and p40 which has the weird DFS 228/P 135 hybrid description on it.

The 28 break down as:
Single-seat fighter - four projects
1938 fighter with rotating wing
1941 P 75
1944-45 P 130
1944-45 P 135 (in parallel with P 130)

Heavy fighter - three projects
1936 similar to Bf 110
1944 heavy weapons mod Ju 188
1944 flying wing

Ground-attack aircraft - five projects (no individual dates, just '1939-43' to encompass them all)
similar to Hs 123
similar to Fw 190
similar to Hs 129
2 x jet single-seater with limited calibre weapons
similar to V-1

Bomber - three projects
1936 4 x Jumo 210
1938 4 x Jumo 210 but canard configuration
1944 4 x BMW 018 tailless

Battlefield reconnaissance - one project
1940 heavily modified two-seater Hs 129

Long-range reconnaissance - three projects
1942 2 engine high-altitude
1943 3 x jet canard
1944 as 1943 but tailless

Commercial/military transport - four projects
1941 2 engine high-speed airliner for DLH
1942 4 engine transatlantic airliner for DLH
1942 as above but diesel-fuelled for DLH
1942 tactical transport for Luftwaffe

Special aircraft - five projects
1941 2 x pulsejet light bomber
1944 unguided missile with glider attached
1944 P 136
1944 P 136 with additional ramjet
(no date) DFS 228/P 135 hybrid

Designs that did not reach even prototype stage did not get B and C ver

While looking into the Hs P.90 (also sometimes referred to as P.600/67 & P.136) as per the drawing for the windtunnel model of it, which you can find in @newsdeskdan Secret Luftwaffe Jetfighters, I noticed the measures of it, stating it to have a wingspan of 1600mm and length of 2340mm, but the important detail is, that the scale as noted on that design sheet was supposed to be 1:10, making it, if correct, a quit large plane at 23,4m length and 16m span and more than double of what is usually given as 11m length and 8m span!

Further a plane this seize would rather qualify for some kind of bomber than a fighter or ground attack craft, which would indeed correlate to the 1941 2x pulsejet light bomber in this list.
Furthermore it would also be fitting to the low project number P.90 since it is much closer to the P.75 and 87 of 1941 than the P.130+s in 1944 (and also seems a logical progression from those canards designs with a pulsejet).

Another intriguing question would be, what kind of big pulsejet engines were envisioned to propell this biggy?
