Vertical takeoff aircraft Yak-36. In 1960, Yakovlev made a proposal to the government to develop the aircraft vertical takeoff and landing (VTOL) Yak-104. The project involved the use of two lifting and propulsion uprated Р19-300 with a thrust of 1600 kgf with a rotary nozzle and one lifting Р19-300 traction 900 kg. It was expected that at flight weight of 2800 kg and the fuel capacity 600 kg VTOL aircraft can reach the speed of 550 km/h, climb to an altitude of 10 000 m and fly to a distance of 500 km.
STAR ANNIVERSARY PARADE
In the first years after the Civil war, the Soviet civil aviation monopoly reigned all-metal aircraft of the German production. “Ukrvozduhput” preferred products of the company “Dornier” and “Dobrolet” and “Zakavia” purchased the aircraft from company “Junkers”. Single-F13 for a long time was the main “workhorse” on the Soviet civil lines, and military transport. Following this, albeit in significantly smaller quantities, began to acquire W33.
Civil war in USA was suddenly brought to the fore a small improvised cruisers who have achieved outstanding success. However, this does not mean that such ships are immediately received universal recognition. Before, during, and after the exploits of the “Alabama” and “Florida” in all countries legislators naval fashion continued construction of large steam frigates, which was still considered most appropriate for action on ocean communications.
Recall. During the Second world war working on jet engines were in Germany on a broad front. They are ahead in this area all of the country and was able to convey in the production of two types of TRD – Ju-YuMO 004 and BMW 003. Equipped with their first jet aircraft – the Me 262, he 162 and ar 234 was the undoubted success of the German scientists and engineers. These aircraft are widely known, but the design idea was not on, and the command of the Luftwaffe in July 1944, announced a competition for the creation of the fighter that can replace the Me 262 and had the best flight and operational data.
All-wheel drive SUV UAZ PATRIOT. SUVs are in fashion now. The highway was filled with jeeps of all sizes and kinds — from toddlers, in size far ahead of the domestic “Oka”, to giants, created, appears, on the basis of dump trucks. But if in countries with well-developed road network, the acquisition of the Rover —a tribute to the windy fashion in Russia, with its snow and off-road, four-wheel drive all terrain vehicle becomes imperative.
MERCEDES R-class. The modern market cars to the limit filled with cars of various types, which, however, can be grouped into clearly-defined classes that allows the buyer to compare vehicles according to their technical characteristics and prices in order to offer dozens of vehicles to choose only one. Accordingly, firms-producers to create new machines “tied” them to a particular class and, consequently, to the already established consumer group.
Sunset armored forces is inevitable — that is the conclusion reached by many military experts in the late 30-ies. The reason for this was the emergence of numerous anti-tank artillery, able to quickly shift the fire from one target to another and hit 30-40-mm frontal armor of all types these formidable machines. Although the duel armor and the projectile won the last, the designers have continued the search for reserves the survivability of tanks and seemed to have found a way out of the impasse. So, relying on the blitzkrieg, Hitler’s engineers created a high-speed machine guns 37-55 mm caliber and two or three machine guns. But high mobility (up to 55 km/h) was due to the weak armor protection. For example, the main tank of the German army T-W had a speed of 45 km/h, 37-mm gun, three machine guns, 30-mm front and 15-mm side armor. It was believed that the mass of fire and high mobility will be able to paralyze the anti-tank defenses, will allow tank units to penetrate deep into the attacked country, to seize her vital centers before it will be organized serious resistance.
Nickname firmly entrenched behind the “Ford-T” — auto, “copies” which for two decades was 15 007 003 instance. This amazing car deserves to be told separately. Thanks to her Henry Ford became “road king”, and millions of Americans turned from pedestrians to motorists. “Ford-T” was the first in the world began to assemble on the conveyor, it has spawned countless anecdotes and legends, and historians of motoring has got a rich material for research.
Enlisting in the First world war, the warring countries have moved from a flat ground-water surface warfare in three-dimensional space: clumsy aircraft, recently entertained the public at fairs began to turn into a formidable fighting machine. While “under the gun” was supplied all flying equipment — including lighter-than-air: balloons became the eyes of the army and Navy, but better airships turned into bombers.
The command of the Bundeswehr started the revival of its airborne forces in the late 1950s, However, as in the days of the Wehrmacht, look at VDV was still as highly mobile light infantry without any means of “motorization”, not to mention the armor.
