Blohm & Voss BV P.215
« on: January 23, 2011, 11:57:45 AM »

Hello everyone, I have always find this aircraft to be very interesting and I have spend alot of time researching about this interesting aircraft.  This aircraft is one of these aircraft that I would love to see in IL-2 1946 one day.  I have great information on this aircraft, I hope this community will enjoy this and discuss about this aircraft.

Blohm & Voss BV P.215

Information:

Jet Planes of the third Reich, The Secret Projects Volume One by Manfred Griehl

Quote
The BV P 215.02 was a h ighly unorthodox design.  It had sharply sweptbackwings, the tips having anhedral and carrying control surfaces which acted as elevators and also partly as ailerons and rudders.  Inboard of each of the anhedral tips was small vertical rudder.  Slotted flaps occupied the entire length of the trailing edge of the main wing.  The large fuel tanks were installed in the wings, which were of constant chord.  The BV 215 was powered by two HeS 011 A-1s mounted in the extreme tail of the fuselage.  A large single intake in the nose fed air via a bullet-shaped fuselage carried the armament and radar equipment.  The crew of three, seated in a pressurized cabin, consisted of pilot, radio operator, and rear gunner.  The defensive armament normaly comprised one FLH 151 remotely controlled barbette, located on top of the rear fuselage.  Installation of two oblique upward-firing MK 108 guns with 100 rpg was also possible.  The main forward armament was the heaviest ever proposed for a German night fighter, the standard offensive armament comprised up to five MK 108s with 200 rpg.  Later, four X-4 or R 100BS missiles on underwing racks in conjunction with advanced Oberon weapons release system were also proposed.

All three wheels of the tricycle undercarriage retracted into the fuselage, the nosewheel of 30.3 x 1.1 in (700 x 270 mm) was taken from He 219 night fighter.  The mainwheel size was 48 x 1.75 in (1220 x 445 mm).  The BV was also to be employed as an effective fighter bomber in emergencies, able to carry up to two SC 500 bombs semi-recessed in the fuselage in order to reduce air drag.  The description of thei design was finished in March 1945, and submitted to the Chef TRL by mid-month.  Further development was stopped, because construction was considered too expensive under the prevailing conditions.

Other proposals sent to the Chef TLR in March 1945, included an advanced version of the P 215 possessing an endurance of three hours at full throttle and a service ceiling of nearly 42,650 ft (13,000 m).  however, the design finally submitted to the authorities had the much inferior endurance fo 1 hr 39 min at the combat altitude of 36,090 ft (11,000 m) at full throttle.  At a flying weight of 22,046 lbs (10,000 kg) and one-hundred percent thrust, a speed of about 535 mph (860 km/h) was predicted.  Despite this perfomance, there was no chance for the construction of prototype due to preoccupation of the Blohm & Voss development department with their BV 155 high-altitude piston-engine fighter, the first prototype of which flew in early 1945.

  A specification was issued by the Technische Luftrüstung (Technical Air Armaments Board) in late January 1944 for the definitive night fighter. Preliminary requirements were to be a top speed of 900 km/h (559 mph), an endurance of four hours, armament consisting of four cannon and internally mounted radar (FuG 240 or 244).  Dr. Richard Vogt, who designed the BV P.212, immediately began work on an aircraft  to meet the specifications issued for the new night fighter. Vogt used the BV P.212 as the overall basis for the new BV P.215 night fighter. The fuselage was short, with an air intake in the nose leading directly to the two Heinkel He S 011 mounted in the rear fuselage. As with other Blohm & Voss Vogt designs, the fuselage structure was built up out of the intake tube, and all components attached to this structure (see the BV P.211.02). The wings featured a 30 degree sweepback and 6 degrees of dihedral; internally the support came from a wide wing box, constructed from
welded steel. The outer wing tips angled down at 23 degrees, and assisted stability and control. Warm air diverted from the engine compartment was circulated through the wings for de-icing purposes.

There were two small vertical fins and rudders located on the trailing edge of the wing, where the outer wing tips angled downwards. Total fuel capacity was 7800 liters (2061 gallons), stored mainly in wing tanks. An ingenious system to pre-heat the fuel was designed; a pump would circulate the fuel of the fuselage feeder tank through a spiral line around the engine compartment and into the wing tanks. The nose landing gear was taken from the Heinkel He 219 and retracted to the rear, and the two main wheels (angled forward by 16 degrees) also retracted forwards into the fuselage. The
pressurized cockpit held a three man crew; a pilot, radar operator and navigator/radio man, and all three were provided with ejection seats. A wide variety of offensive armament could be carried in the aircraft's nose, and defensive armament consisted of a FHL 151 remote controlled, rear-facing turret armed with either one or two MG 151/20 20 mm cannon. A provision was made for possibly mounting two MK 108 30 mm cannon firing upwards, located behind the cockpit. Two SC 250 250 kg (551 lbs) or SC 500 (1102 lbs) could be carried in a belly recess. The BV P.215's constuction was mainly of metal througout, except for wooden control surfaces and the aircraft's nose. The nose was made of wood because of the installed electrical equipment. The installed electrical radio/radar equipment
is listed below.

In the original Blohm & Voss proposal, it was pointed out that the P.215 was easily transportable. After removing the wings, the fuselage would be easily transportable with no need for specialized lifting equipment. On February 27, 1945, the specifications were upgraded for the future nightfighters, which none of the competitors' aircraft were able to achieve.Although the P.215 would have had good performance figures, it too did not reach the new specifications either. Nevertheless, it was chosen for further development on March 20, 1945. The end of the war ended any further development of this novel aircraft.

Mmmm, I'd love to 'see' one of this family of BV 2.00 series designs ingame.... Apparently they were fairly well in to the windtunnel testing stages by te time the area/factory(/ies) was captured.

Found a newer vid of an BV.215 in Dutch I believe, possible easier to hear/translate than the earlier one...

and another with bad landing wing tip damage reference, and no audio.

As with Soviet 'Tsagi' shared basic design features/concepts like those within/between the MiG-21, Su-17 & MiG-29 Su-27 for example, so was the German aero industry & RLM starting to formulate similar, before they were defeated.
Also similar features in another viewpoint, the Arado E.555

if germany made all of these aircraft they would have raped all of the allies and would have won the war.

I don't think so, but it would have happened differently; longer, more deaths, possible ceasfire on Western Front - increased losses to the 'Mighty Eight' makes greater possiblity of the suspension of daylight raids; assuming the Polesti Raids were intercepted.

But thats hyperthetical, and going off-topic. Edited, at oh so early O' clock (0713-ish GMT)

Sorry for my crap German; I only ever learned it on holiday, I hope this won't offend enough/to much.
 :P thumbs up to Radoye & Solo :)

Lets leave the little napoleon complexed farting vegetarian out of this, there is little time for him, neither has the thread if his moustach twitches, this is about the aircraft, not how it would be his ego-stoking version of 'My moustach over all others'

If Germany made all these planes they'd lose the war even sooner!

Instead of wasting resources on impractical "White Elephant" projects (the V-1 and V-2 rockets that could hardly hit a target the size of Greater London, the V-3 uber-cannon, the Me-163 that shot down less Allied bombers than own planes lost to landing accidents, the Maus superheavy tank that was unable to cross bridges...) the Germans should've concentrated their limited resources into producing more conventional types in greater numbers and deploying them where it counts.

The Sherman and T-34 tanks aren't half as spectacular as the Tiger but the Allies were capable of having them everywhere and in greater numbers than German tanks they would occasionally encounter. The P-51 was nice but nowhere as advanced as Me 262, however the sky was full of P-51's and there rarely was a 262 to be seen.

That's why the Allies won.

@Radoye: Well, the difference is, P-51 were built in great numbers in factories out of reach for any enemy bomber. The German had to produce their weapons in factories which got some bombs on their roof every day. They would have had to use fighters like the Me-262 because the other things would have been not good enough. And they hat enough fuel for Jets.

But I would like to see some of the crazy machines in the game ^^
I have to look for more info about a Bf-109 with Jumo engine (about 50 to 70kmh faster than a G-6)

I like the way the Blohm & Voss BV P.215 looks in flight like a bat it would have been one bad ass night fighter

True. Germany had no hope to out-produce the Allies who had the advantage of US industrial base being well out of harms way.

They would have had to use fighters like the Me-262 because the other things would have been not good enough. And they hat enough fuel for Jets.
There's no question Me 262 was better than the piston engine designs available for Germany.

There's no question Tiger II tanks were better than Pz IV's.

But, with the limited resources they had, maybe it would be better to have 3 Fw 190D-9's and 3 Pz IV's on the battlefield than one Me 262 and one Tiger II.

It took an average of 5 Shermans to destroy one German "Big Cat" tank - but, the Allies had the luxury to sacrifice 5 tanks and have plenty left EVERYWHERE to give support to their infantry, while German infantry had to fight unsupported because their tanks were nowhere to be seen.

And that's what made the difference.
