Mutazione del Westland Lysander?
Ho trovato la foto (che allego) di uno strano velivolo: sembra mezzo Lysander + Mezzo Lancaster.
Dalla livrea sembra risalire alla WWII: qualcuno sa se è mai stato utilizzato e per quale scopo è stato realizzato?

Qui ho trovato alcune informazioni.....
dovrebbe essere il prototipo di un caccia notturno....con quella seconda ala che a tutti gli effetti, se non ho capito male, serviva da un punto di vista aerodinamico per consentire al Lysander modificato di volare con quell'arnese con 4 mitragliatrici installato in coda
E dire che inizialmente pensavo si trattasse di un fotomontaggio....
Comunque, in conclusione...è affascinante come tutto ciò che vola....ma allo stesso tempo proprio bislacco!

Warnehmung / Constatazione
Als ich wiederkeherte / War mein Haar noch nicht grau / Da war ich froh. Die Muhen der Gebirge liegen hinter uns / Vor uns liegen die Muhen der Ebenen
Quando ritornai / i miei capelli non erano ancora grigi / ed ero contento. Le fatiche delle montagne sono alle nostre spalle / davanti a noi le fatiche delle pianure
Bertolt Brecht
Saltate pure e con coraggio di testa nel presente che non ritorna per ritrovarvi in un attimo nel cuore stesso dell'eternità...
Bohumil Hrabal (Brno 1914, Praha 1997)

Interestingly, despite the RAF's warding off a German invasion of Britain in 1940, Britain, like Germany, believed this to be only a temporary postponement, making preparations for the defence of the British Isles still of vital importance. Among schemes put forward for strafing German forces as they hit British beaches or for striking at supporting surface vessels was the Westland P12, a straight modification of the Lysander army co-operation aircraft. Initially planned with two 20 mm cannon attached to the fixed undercarriage legs, a redesign led to the rear fuselage being cut short, a tail gun turret added, and the adoption of a new rear-mounted "tandem wing" with endplate fins and rudders for longintudinal stability. The P12 was first flown on 27 July 1941 and was immediately shown to be highly manoeuvrable. Sent for official trials, it was never put into production as the perceived threat diminished.

e pure queste:
Prototype K6127
After a number of windtunnel tests with models the work on the prototype began. Lysander prototype K6127 lost its original rear cockpit and got a mock-up of a Frazer Nash turret.
Maiden flight: July 27, 1941. Testflights
Testpilot Penrose reports that all was like the original Lysander except that the rudders only became effective at higher speeds. Weird thing was that the airplane proved to be ... more stable. That testflight ended with a loop. Now, if that is not a proof of confidence by its pilot. He sure liked it.
Later tests proved the wide CG range which is common in the Delanne configuration.
During later handling trials they did the tests in three conditions.
1. CG at forward limit (45% of aerodynamic mean chord (AMC))
2. CG at normal limit (52,3% of AMC)
3. CG at aft limit (58,2% of AMC)
Conclusions:
• Rudders were ineffective below 64 km/h (40 mph).
• Little swing to left if loading at aft limit.
• Initial climb was like the original Lysander, only needing a little rudder.
• Aircraft proved easy to fly
• Rudder control became heavy at 450 km/h (280 mph). Below that speed it was rather light.
• The automatic slots in the front wing caused problems when they changed position (close to open).
• Dives were "smooth and remarkably steady".
The end of the Lysander P12
Before full tests were done, the official support was lost. The P12 was official off duty on June 13, 1944.
