While serving Mother Russia, Bartini became known for being a master in the art of aircraft engineering, and even created the first widebody aircraft, the Bartini T-117. Over the years, his experiments and knowledge led to a vehicle dubbed the VVA-14. What makes the VVA-14 is the fact that it harnessed the ground effect.
If you’ve never heard of the ground effect, it’s a rather simple physics effect that appears as fixed wing aircraft fly close to ground levels, mainly water surfaces, as they offer better transmission of the effect due to a lack of obstacles on the surface.
natural airflow around the wings is disrupted due to the ground’s surface, and instead of passing around the wing and trailing off, some air is trapped between the vehicle and ground and is compressed, creating a pocket of air underneath the vehicle. The result? Increased lift and decreased drag, and higher efficiency.
One main difference between commercial airplanes and ground effect craft is size and weight. To harness the ground effect even more, a vehicle’s weight helps keep the compressed air under the fuselage, leading to a successful effect.
In order to harness this effect to the fullest potential, Bartini modified every aspect of the VVA-14, down to the tips of the wings, which featured downwards winglets. The first and most important aspect is the body shape. To create a nice pocket of compressed air, the VVA is constructed with an extra-wide body that includes two fuselage compartments that each have their own empennage at the rear. It’s these two fuselages’ that help compress air even more than standard aircraft.
For the eventual tests, two bypass turbo jets granted the VVA-14 a top speed of 760 kph (472 mph) and reach an altitude of 33,000 ft (10,058 m). But it was those lift engines that made the whole machine as versatile as it was meant to be.
Since it was initially meant to seek and destroy submarines, the VVA-14 was to be equipped with magnetic anomaly detection systems, and over two tons of boom boom including torpedoes and depth charges.
Funny enough, construction was slow, and the VVA-14 saw its first test flight in 1972. Any submarines were probably long gone. The final vehicle was to be developed in three subsequent stages with the third stage seeing the equipping of firepower.
abandoned the project for more modern airplanes and fighters.
Nonetheless, the VVA-14 did work and was able to optimize the ground affect at 8 m (26 ft) above the ground surface and stood to sustain Bartini’s out-there ideas and designs, eventually leading to other designs meant to go faster, further and higher, but all were based on the ground affect. One of which was an massive aircraft carrier for the Soviet Navy. I wonder how long it’s going to be until someone makes a modern vehicle that uses the ground effect.
