The Kamov Ka-25 (NATO reporting name 'Hormone') was a naval helicopter, developed for the Soviet Navy in the USSR from 1958.
In the late 1950s there was an urgent demand for anti-submarine helicopters for deployment on new ships equipped with helicopter platforms entering service with the Soviet Navy. Kamov's compact design was chosen for production in 1958. To speed the development of the new anti-submarine helicopter Kamov designed and built a prototype to prove the cabin and dynamic components layout; designated Ka-20, this demonstrator was not equipped with mission equipment, corrosion protection or shipboard operational equipment. The Ka-20 was displayed at the 1961 Tushino Aviation Day display.
Definitive prototypes of the Ka-25 incorporated mission equipment and corrosion protection for the structure. The rotor system introduced aluminium alloy blades pressurised with nitrogen for crack detection, lubricated hinges, hydraulic powered controls, alcohol de-icing and automatic blade folding. Power was supplied by two free-turbine engines sat atop the cabin, with electrically de-iced inlets, plain lateral exhausts with no Infra-Red countermeasures, driving the main gearbox directly and a cooling fan for the gearbox and hydraulic oil coolers aft of the main gearbox. Construction was of stressed skin duralumin throughout with flush-riveting, as well as some bonding and honeycomb sandwich panels. The 1.5m × 1,25m × 3.94m cabin had a sliding door to port flight deck forward of the cabin and fuel tanks underfloor filled using a pressure refueling nozzle on the port side. A short boom at the rear of the cabin had a central fin and twin toed in fins at the ends of the tailplane mainly for use during auto-rotation. The undercarriage consisted of two noncastoring mainwheels with sprag brakes attached to the fuselage by parallel 'V' struts with a single angled shock absorber to dissipate landing loads, and two castoring nosewheels on straight shock absorbing legs attached directly to the fuselage either side of the cockpit which folded rearwards to reduce interference with the RADAR, all wheels were fitted with emergency rapid inflation flotation collars. Flying controls all act on the co-axial rotors with pitch, roll and collective similar to a conventional single rotor helicopter. Yaw was through differential collective which has a secondary effect of torque, an automatic mixer box ensured that total lift on the rotors remained constant during yaw maneuvers, to improve handling during deck landings. Optional extras included fold up seats for 12 passengers, rescue hoist, external auxiliary fuel tanks or containers for cameras, flares, smoke floats or beacons.

In summary, the development trend of foreign cold roll forming machine production can be summarized in several aspects:
1. The output of cold roll forming machines continues to increase
Since the 1960s, the output of foreign cold roll forming machines has increased rapidly. This is the general trend. According to the statistics of cold roll forming machines in various countries over the years, the output of cold roll forming machines and the output of steel have been relatively stable at a certain level. The ratio is generally 1.5:100 to 4:100.
For example, in the development plan formulated by the former Soviet Union in 1975, it was stipulated that the output of cold roll forming machines in 1990 would account for 4% of steel output. With the improvement of the production process of cold roll forming machines, product specifications and varieties continued to increase, and product quality also with continuous improvement, the scope of application is expanding. The former Soviet Union was re-regulating the original development plan in 1979, stipulating that it will reach 5% in 1990. Some other countries also plan to increase the output of cold roll forming machines. The output of foreign cold roll forming machines is about 10 million tons per year, accounting for 3% of the world's total steel.
2. The research work of cold roll forming machine is deepening
Research work on roll forming theory, forming process and forming equipment is in-depth abroad, and a series of progress has been made in the research work on the practical application of cold roll forming machines. For example, the former Soviet Union and the United States have used electronic computers to study the force and energy parameters in cold roll forming and discuss deformation methods with low energy consumption.
3. The new technology of cold roll forming machine continues to appear
Since the roll forming process was successfully studied in the United States in 1910, after decades of improvement and perfection, the forming process has become more mature. As the technical and economic effects of cold roll forming machines in practical applications have become increasingly recognized, cold roll forming machines have been widely used in various fields of the national economy. Users have more and more stringent requirements on the quality of cold roll forming machines, and require diversification of varieties and specifications, which promotes the continuous improvement of roll forming processes to adapt to user requirements. Foreign countries have adopted roll forming processes and developed corresponding equipment. A vertical-spoke forming machine with a plug-in type, and a forming unit with centralized adjustment of forming rollers is referred to as CTA unit (Central Tool Adjustment), straight edge forming unit.
4. The product variety of cold roll forming machines is continuously increasing, and the product structure is constantly updated
With the development of the production of cold roll forming machines and the expansion of the scope of application, the variety of cold roll forming machines continues to increase, the product structure is constantly updated, and the product standards are gradually improved. With the continuous emergence of new processes, the range of blank materials and specifications has been expanding. There are more than 10,000 varieties and specifications of cold-formed steel produced abroad. Among them, the specifications of the cold roll forming machine range from: blank unfolding width 10mm-2500mm, thickness 0.1mm~32mm.
From the perspective of the material of the cold roll forming machine, before the 1970s, it was mainly carbon steel, accounting for about 90%; since the 1970s, through the technical and economic comparison of practical applications, the use of high-strength low-alloy steel, alloy steel and stainless steel has been promoted. With the proportion of ordinary carbon steel products has decreased year by year, and the proportion of alloy steel, high-strength low-alloy steel and stainless steel products has increased year by year.
