The story of VVA-14 amphibian

Like they called it in Soviet Republics - "The Beriev's Cow"

Terms required to know:

Ekran (Screen) phenomena - change of lift-generating properties
of a wing at extremely low height flights - discovered by aviators.



VVA-14 before test flight

In the early 1950s (correct me if
I'm wrong) R.L. Bartini working for OKB Beriev introduced new idea of using Ekran
phenomena for improving take off/landing properties of an aircraft. According to
N.A. Pogorelov, primary assistant designer of R.L. Bartini, the main aim was to
realize ideas of contactless take-off and landing: an aircraft lifts itself
above the ground or waterbody a little bit and then begins its take-off run leaning
against the "ekran". If this would ever come true, a revolutionary
aircraft technology would've been invented which would require no runways and
gave considerably greater performance advantage over the average VSTOL
jets.

 

Converted 14M1P version featuring two take-off boosters at the
very front


According to the above concept, two technology anti-submarine
testbeds were built under VVA-14 designation. VVA stands for "Vertikal'no
Vzletaushaya Amfibia" or Vertical Take-off Amphibious aircraft. Due to
contactless take-off and landing, a better marine performance was achieved, the dream
of takeoff and landing on sea under any kind of weather conditions became a
reality. Vertical take-off ensured special gas-pillow which magnified itself
within the fuselage using two air compressors (so basically a huge balloon was
formed inside of that plane). In 1976 one of these prototypes was rebuilt into
ekranoplan. It was designated 14M1P (see illustration). Designers placed to
additional D-30M engines on the nose of the aircraft for the purpose of
increasing airflow under wings, rubber landing gear was replaced with more
durable one made out of metal.

(beneath the plane) trials


Some time after R.L. Bartini passed away in 1974, and all works
on the project were cancelled under great pressure of OKB Beriev which was
developing A-40 and A-50 anti-submarine amphibians and wanted no competition.
One of remaining prototypes, VVA-14 #10687, crippled after a fire accident, without a tailplane,
engines and wings was delivered to Monino where it slowly, but surely grows a
thick layer of rust up to present days. The sight is awful I must say.
