"Shvabe" scientists have patented optics with increased reflection

-

 


The development relates to the field of instrumentation and can potentially be used as an optical element in laser technology operating at a wavelength of 10.6 microns, and at the same time - in various optoelectronic devices for a wide range of the spectrum. Its authors were specialists of the NGO "State Institute of Applied Optics" (NGO HYPO) from Kazan.

A feature of the invention is that the reflective layer of the mirror is made of a thin aluminium- copper film of alloy with a thickness of 200-400 nm, and the protective layer is made of lutetium oxide with a thickness of 100-250 nm.

"The reflection coefficient of the proposed optical mirror is 0.1–0.4% higher in the visible, medium and far spectral IR ranges than that of the prototype. In addition, gold, which is a precious metal, is used in the reflective layer of the prototype. Aluminium and copper used in the reflective layer of the proposed optical mirror are ten times cheaper," said Villen Baloev, Director General of NPO HYPO.

The Institute has been conducting research and development in this direction for more than 60 years. During this time, vast experience has been accumulated in the development of antireflective, filtering, dichroic, highly reflective, beam-splitting, protective coatings with high optical and operational characteristics for a wide range of spectrum from 0.25 to 25 microns.

BMP-3 with "Karkas-1"/"Karkas-2" ERA packages

-
Image
  Shown at an exhibition in Omsk in 2001. ERA  blocks are located on the side and frontal parts of the hull and turret together with rubber fabric and lattice screens.  Additional protection significantly increases the survivability of the BMP-3. Advertising information of those years stated that the BMP-3 with the "Karkas-1"/"Karkas-2" was capable of withstanding the impact of HEAT grenades (RPG) with armour penetration up to 550 mm.  Also, reactive armour blocks increase the armour's resistance to damage from bullets of 14.5 mm calibre. Only known image of a BMP-3M swimming with the additional armour package. Further topic on BMP-3 ERA package

GTD-1000 - GTD-1000TF - GTD-1250 Gas Turbine Engines

-
Image
The world's first mass-produced tank gas turbine engine GTD-1000T was created at the Klimov Plant in 1968 for the T-80 main battle tank developed By the special tank design Bureau of the Kirov plant (now JSC "Spetsmash"), which was adopted by the Soviet Army in 1976. Since 1980, a modification of the GTD‑1000TF for T-80B/BV tanks was produced, since 1986 a modification of the GTD-1250 for T-80U tanks.  GTD-1250 Engines of the GTD-1250 family as part of the power plants of T-80 tanks are in service with the armies of Russia, Belarus, Cyprus, South Korea, Kazakhstan. Turbine engine GTD-1000T/GTD-1250, which have a large volume-weight  capacity and a more favourable traction characteristic compared to diesel engines, provide T-80 tanks with interesting characteristics: - higher operational readiness - easy start-up at low temperatures (up to -40°C) - better cross-country ability on soils with a low load-bearing capacity - best noise and heat-masking qualities - increased &qu

BMP-3 ERA topic continuation

-
Image
This post expands on a previously covered topic, being the BMP-3 with ERA . Potentially sealing this topic until later when more information comes to light.  ERA package components:  ERA containers filled with 4S24 ERA elements, containers are mounted on the front and both sides of the hull. Slat armour mounted on the rear of the vehicle protects the engine compartment. Overall package performance:  Protection against AT rocket-propelled grenades (RPG) PG-7V, PG-7VS, PG-7VL, PG-7VM, PG-9S and other types of grenades capable of penetrating up to 600mm RHA within a 180 ° fire arc.  In areas covered by ERA containers, the probability of protection is at least 80%.  In areas covered by slat armour, the probability of protection is at least 50%. Protection against small arms:  Areas covered by ERA containers 12.7mm B-32 rounds at 0m within 180 ° fire arc 14.5mm B-32 rounds at 50 m within 180 ° fire arc Areas covered by slat armour and steel plates 12.7mm B-32 rounds at 35 0m within 180 ° fi
