Russian aerodynamics specialists have undertaken analysis of various ditching scenarios for the Irkut MS-21 twinjet.

The tests have involved launching a model with a catapult at various speeds and with differing pitch angles.

Russia's Central Aerohydrodynamics Institute says the characteristics of a forced landing on water cannot be reliably obtained without experimental data.

The model has been fitted with an embedded recording device, it says, to capture "splashdown" data.

Tests have been carried out at the institute's branch at Dubna, north of Moscow.

"Data from the experiment will be used for further engineering work on the MS-21," it states. Another phase of testing will take place in July.
