Paint and camouflage

Image
To camouflage AFVs and increase the difficulty of being spotted using day-night observation devices, a variety of different paint schemes paired with specifically designed camouflage patterns can be used. Vehicles are painted using a base coating of enamel, which has chemical durability and specific spectral characteristics. To add camouflage, secondary colour enamel spots are added onto the surface of the vehicle. Camouflaging can be achieved by combining different camouflage methods into one single design: colour differentiation between primary paint coat and secondary colour spots, different values of reflection coefficients in the infrared (IR) spectrum and a special pattern design, deforming the visible silhouette of a vehicle. To create basic camouflage schemes, 2 different enamels were used: HV-518 is used as the base paint and NC-1200 for spots. Enamel HV-518 would protect the vehicle from being detected by passive IR devices only in the spectral range over 0.85 micrometres but...

Pionierbrücke 2000

In the upcoming few days and possibly weeks, I will be uploading images taken during the Austrian national holiday, which is celebrated on the 26th of October.  This being the first showcase held after the pandemic, a large number of people were present and taking images/videos was difficult.  -------------------------------------------------------------------------------------------------------------------------------- Discord --------------------------------------------------------------------------------------------------------------------------------

T-54/T-55 with GTD-3T gas turbine engine

Image
In the early 1960s, an R&D program was launched to create a promising next-generation tank. T-54 and T-55 tanks served as the basis for various running models, designed to test new components and systems. The GTD-3T gas turbine engine and its supporting systems, the hydromechanical transmission, the placement of the driver in the turret, automated control drives, as well as the chassis of new experimental tanks were tested on these models. T-54 with GTD-3T Between 1960-1961 Factory No.174 (Zavod No.174) and VNII-100 created a mobility trial mockup using a T-54 and fitted it with a GTD-3T gas turbine engine which unregulated produced 515kW (700 hp), during the installation process the turbine engine's performance was reduced to 318kW (432 hp).  Compared to the baseline T-54, the new variant mainly had its engine-transmission bay changed. The GTD-3T displaced more inner volume compared to the standard V-54 diesel engine. Larger volume displacement meant that the engine was 140 mm...
