Airbus Helicopters is developing a smoke screen to be deployed from its H145M helicopter when inserting troops in the hover, a senior company representative said on 4 November.

Speaking on the opening day of the Airbus Defence and Space (DS) Trade Media Briefing 2019 at the company’s Donauworth facility near Munich, Mark Henning, Senior Programme Manager H145M Governmental Business, said that the system, which is a first for helicopters, has shown positive results in early ground-based tests.
“We are developing an in-flight rapid obscuration system to make the H145M invisible during the most dangerous phase of its mission – when hovering at about 20 m when dropping troops. This has been done for vehicles, but never before for helicopters. We have proven it conceptually, and the results have been very good,” Henning said.
As Henning noted, the system works by equipping the helicopter with side- and under-fuselage mounted smoke dispensers that when fire create “a fence” of obscuring smoke around the aircraft. This smoke obscures both the helicopter’s visual and infrared signatures.
Ground-based tests had shown that the smoke screen is not dissipated too quickly by the helicopter’s rotor downwash, and that it stays stable long enough to protect the helicopter during this critical phase of the mission profile.
Henning stated that, with the smoke screen obscuring the helicopter from the ground, the pilots must be equipped with a helmet-mounted display system so as not to cause a loss of reference with the ground that could lead the aircraft to crash; a condition more commonly referred to as ‘brownout’.
