Any info on this Ju-88?
Does anyone know anything about this aircraft?

Re: Any info on this Ju-88?
Beautiful photos, Bob.
Here is what I have on W.Nr. 4001: Ju 88A-4, W.Nr. 4001, IV./KG 30, 24-Oct-43, Technical failure, Denmark, NW of Aalborg, Bruch 20%. However, I think your photos show another accident, which happened at another (school?) unit and not in Denmark, but rather somewhere South. What is the complete code on the fuselage (T_+AL)? |

Hey
This wheels-up landing plane was the Ju 88 A-1 / 4001 / TC + AL. This aircraft belonged to Gr.KFS 2 and made a crash-landing because engine-trouble on 27. May 1941 by Puttling. The damage was 25 %. Latre the plane was repaired by Junkers-aeroplane repair-shop in Breslau-Langenau and flown there from 08. March to 07. April 1942. Does anybody knows the time and place of manufacturing. JoMe |
Re: Any info on this Ju-88?
Could it be a A-12?
I have info that this aircraft was with FFS (B) 6 in 1943 as a A-12. Regards, Norbert |
Re: Any info on this Ju-88?
I made a mistake it should be FFS (C) 6
Sorry, Norbert |

Re: Any info on this Ju-88?
I am not at home, so I can't confirm the original assembly date, but it has to be late 39 or early 40, I will check also the assembly location when I get home tonite. At the time of the crash in 1941, the a/c was probably not an A-12 (which were all umbau a/c) as I really don't think any were converted to that subtype until later.

Hi all
W.Nr. 0884001 etc.. Delivered in * March 1940 to January 1942 Serie Ju 88 A-1 / A-5 / A-4 (Dive-Bombers) Lizence made fuselages by Norddeutcher Dornier Werke GmbH (Wismar <Perleberg?>) mounted with HWO wings, but Dornier-Sud (Friedrichshafen) made tails (Block II). * Start of deliveries from NDD is belived around late February or early March 1940 [author]. The following is from BA-MA ´Schulen´ losses: (W.Nr. 088)4001 Ju 88 A-1 / A-5 Gr.Kampffliegerschule 2 (Lw.Befh.Mitte) Non-OPS (S) engine failure and belly landed (25%) at Sauthern near Platting 27.05.1942 (BS Gefr. Willi Krebs and F Uffz. Wilhelm Kolatschek killed <amd in a/04.06.42>) - Ju 88 A-12 FFS B 6 (Luftflotte Reich) Non-OPS (S) technical troble and belly landed (15%) at Kolberg 22.06.1944 (F Uffz. Wilhelm Janßen injured) Note the straight tip of the rudder, caracteristic of early A-1 / A-5 series machines.... also VDM (Metal) propellers... but it has A-5 type rear Beetle-Eyed twin-gun canopy frame... edNorth |
Re: Any info on this Ju-88?
I guess FFS B 6 was correct after all.
Thanks for the clarification, Norbert |

Re: Any info on this Ju-88?
W.Nr. 4001 was assembled at NDW Wismar. There were 3 a/c assembled in Jan. and 4 in Feb. 1940. This was probably one of those, but acceptances did not always (in fact, almost never) follow exact W.Nr. sequence as a result of problems that might require rework and additional flight testing. My records indicate A-12 conversion deliveries began in Mar. 1943. I believe the A-12s would all have had wooden props and the intercooler arrangement as per A-4, C-6, etc.

Re: Any info on this Ju-88?
Hi all
Ok - I guess ´ArtieBob´ has all the numbers lined up ???? Was W.Nr. 0884001 accepted by RLM BAL Perleberg or some other location ????? edNorth |
Re: Any info on this Ju-88?
Since the 1st photo shows a wingtip unit beyond the aileron tip, it would probably be an A-5 rather than an A-1.

Re: Any info on this Ju-88?
Hi all
Yes I saw the wingtip also. The span was increased to lower VMC (Single engine minumum safety speed) and all surviving A-1´s upgraded after autumn 1940... however the basic airframe was still the Serie A-1. edNorth |
Re: Any info on this Ju-88?
Can you clarify this point, please? Improvements to the Vmc will normally come from changes to the directional stability (yaw) - i.e. larger fin/rudder. Extending the wingtips would improve the lateral stability (roll).
Indeed, increasing the wing area will have reduced the take-off speed, thus increasing any interval between Vunstick and Vmc, thus placing the aircraft more at risk? Admittedly the two stabilities tend to be linked - in this case yaw leading to roll as one wing "digs in". I can see how a reduction in the rate of roll due to yaw would be beneficial during this stage, but increasing the span wouldn't have been the change of choice to improve Vmc, surely? |
Re: Any info on this Ju-88?
Hi Graham
Well. Yes you may have a point there. I´m perhaps not the best person to explain this in detail. An qualified engineer likely could do better. But if you extend the wing you get higher ´aspect ratio´ - then ´smaller in velocity wingtip wortices´ and hence less drag flying at an high angle of attack, such as flying near Vmc just after take off - or thus flying at lesser angle of attack creates the same amount of lift - Then yes losing power on the ´critcal engine´ <the left engine> flying at below Vmc will lead to disaster - but solution to that is reducing the power on the good engine, pushing the stick forward to pick up speed and control is <hopefully> regained (but with small or large sink-rate). If too low altitude an controlled crash may result! The quotation on lower Vmc I saw somewhere but may be confusion to lowering the wingloading and or lowering the stall speed. Anyway I would have extended the original Ju 88 A-1 wings on account of ´lesser drag/greater range/more payload and likely better manoverability with more effective inset-ailerons. Having surveyed Ju 88 losses it indeed comes to light ´very high rate of belly-landings due to engine failures´. So If you had lost the critical engine a Ju 88 you might have been trained to land wheels up, rather than to lower the wheels and thus creating greater drag and stalling on final approach. Anyway I have never flown an Ju 88 but I have limited twin-flying experience on light-twins; once actually landing with an ´dead´ engine... ... and yes the fin and rudder was indeed enlarged on the Ju 188 E & Ju 88 G. cheers edNorth |
