Fenestron

A Fenestron (or fantail, sometimes called "fan-in-fin") is a shrouded tail rotor of a helicopter that is essentially a ducted fan. The housing is integral with the tail skin and like the conventional tail rotor it replaces, it is intended to counteract the torque of the main rotor.

Interesting picture - Mi-24A with the fenestron:

Autorotation

Using autorotation helicopter can be landed safely in the event of complete engine failure. Consequently all single-engine helicopters must demonstrate this capability in order to obtain a type certificate.

The height–velocity diagram (for a specific helicopter) shows the flight profiles, where autorotation can be safely performed.

Articles on Wikipedia about autorotation and H/V diagram:

 

If main engine or both engine fail, but helicopter was operated in the safe H/V profile, then it is possible to land safely. It is a safety feature of hely, so don't be afraid to fly! ;)

Another scale model of Ekranoplan Lun

Anigrand 1/144 Ekranoplan Lun by (sky_devil)

This model is better then the one from the previous post, but it is still missing some parts, which I would like to see:

• copper protection on one of the engines
• the ailerons on the wings should be down

Kamov Ka-26 rotorhead looks very complicated. Would be nice to find a model of it to see how it works...
