The concept was radical: a small, unpowered glider towed to altitude by a Messerschmitt Bf 109G, then released to dive through bomber formations at speeds approaching 900 km\/h. The pilot lay in a prone position to reduce frontal area and withstand the extreme g-forces of the attack dive — up to 14 g during pull-out. Armament consisted of two 30 mm MK 108 cannons mounted in the wing roots, each with 35 rounds.\u003c\/p\u003e\n\u003cp\u003eSeven prototypes (V1 through V7) were constructed and 17 test flights recorded between 1943 and 1944. Testing revealed significant weight overruns — prototypes were found to be heavier than designed, requiring the removal of some armor and one cannon for flight trials. Engineers also noted that at the highest projected dive speeds, aileron flutter would have made the aircraft uncontrollable. Despite these challenges, the concept attracted serious engineering attention, with proposals for rocket-assisted return flights using the HWK 109-509B bi-fuel engine (as fitted to the Me 163 Komet), Argus pulsejets, and alternative weapon loads including R4M rockets and anti-ship torpedo configurations. The program was ultimately cancelled as the strategic situation deteriorated and resources were redirected.\u003c\/p\u003e\n\u003cp\u003eThe BV 40 remains a significant example of late-war German engineering ingenuity under resource constraints — a design that attempted to solve a complex tactical problem with minimum materials and maximum pilot courage.\u003c\/p\u003e\n\n\u003ch2\u003eManuals Included in This Collection\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBV 40 Armament Manual\u003c\/strong\u003e — MK 108 Aircraft Machine Cannon, Flugzeugmaschinenkanone MK 108 (German language)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBV 40 Construction Manual\u003c\/strong\u003e — BV 40 Aircraft Construction Descriptions Manual, Baubeschreibung (German language)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBV 40 Flight Manual\u003c\/strong\u003e — BV 40 Flight Operating Instructions Manual, Bedienungsvorschrift Fl (German language)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBV 40 Technical Publications\u003c\/strong\u003e — Secret Glider Fighter, Allied Technical Intelligence Report (English language)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eTogether these four documents cover the aircraft from the perspective of its designers, its pilots, and its adversaries — providing a uniquely multi-dimensional view of this experimental interceptor.\u003c\/p\u003e\n\n\u003ch2\u003eEngineering Norms and Standards\u003c\/h2\u003e\n\u003cp\u003eThe BV 40 was developed under Luftwaffe procurement standards of the 1943–1944 period, with documentation produced in accordance with German military technical publication conventions (Vorschriften). The MK 108 cannon documentation follows Rheinmetall-Borsig technical manual standards. The Allied intelligence report reflects USAAF\/RAF technical intelligence methodology for captured or recovered enemy aircraft assessment. Prototype testing adhered to Erprobungsstelle (test establishment) procedures, with flight data recorded across 17 documented test sorties.\u003c\/p\u003e\n\n\u003ch2\u003eTechnical Specifications\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eWingspan:\u003c\/strong\u003e 7.9 m (25 ft 11 in)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength:\u003c\/strong\u003e 5.7 m (18 ft 8 in)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeight:\u003c\/strong\u003e 1.63 m (5 ft 4 in)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWing Area:\u003c\/strong\u003e 8.7 m² (94 sq ft)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEmpty Weight:\u003c\/strong\u003e 835–838 kg\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLoaded Weight:\u003c\/strong\u003e 950–952 kg\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Dive Speed (design estimate):\u003c\/strong\u003e 900 km\/h (560 mph)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRecorded Maximum Speed:\u003c\/strong\u003e 470 km\/h (292 mph)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTowed Speed:\u003c\/strong\u003e ~554 km\/h (behind Bf 109G)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAttack Speed:\u003c\/strong\u003e 475 km\/h at 20° dive\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLanding Speed:\u003c\/strong\u003e ~118 km\/h with flaps\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eArmament:\u003c\/strong\u003e 2 × 30 mm MK 108 cannon, 35 rpg\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrototypes Built:\u003c\/strong\u003e 7 (V1–V7)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTest Flights Recorded:\u003c\/strong\u003e 17\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eFormat and Delivery\u003c\/h2\u003e\n\u003cp\u003eAll manuals are delivered as high-resolution PDF files, optimized for screen reading and printing.
