I remember a few years ago in the journal “modelist-Konstruktor” there is the material possibility of measuring electrical capacitance using a PC “Specialist”. Then published the program in machine code that allows with reasonable accuracy to determine the values of capacitors in the range of 0.1—1000 UF, and later version of it written in forth language, for which the wording, of course, a huge thank you!
We are not talking about armored planes-fighter planes or combat helicopters, and about real tanks on the tracks. But with wings. It came up in the early 1930s, American designer Walter Christie’s tanks. He proposed to attach to the tank wings and tail, and his powerful motor to make spin the propeller.
The first and most important work on the rotating propeller to generate lift forces were made in the period between the world wars. Thus, it was found that the spinning rotor can generate lift force, maintaining its rotation from the incoming flow. Any drive to the rotor in this case was not needed. This mode is called “autorotation”. Its use allowed the Spanish designer Juan de La Cierva to invent the autogyro.
Specialists, no doubt, will note the advantages of a new car company Renault — RENAULT MEGANE COUPE. Memorable appearance, underlined “big-eyed” slanted headlights and back symmetrical they grilles air intakes at the front of the hood — that’s not all.
The entire model except for the axles and the engine is made of paper and cardboard. It can make students 3rd-5th grade. The model is like a real machine of the separately mounted parts, so building it is best to deal with just a few people. Before proceeding to the construction of the model, it is necessary to review the plans, collect all materials and tools. It is necessary to increase the drawings in the correct scale and make sure they are correct.
(Continued. Beginning in № 9’01). To making a universal charging apparatus, it is recommended to proceed only after at hand will be all you need, including tools and supplies. Case size mm 300x200x200 taken or prepared, as the front panel (300×200 mm), handmade. Transformer power 250 VA, is wound on the magnetic core SHL 50×32 mm (for calculations it is more convenient to use the units of measurement universally accepted Amateur practice, when the cross section of the magnetic circuit is expressed in cm2; in relation to the SHL package recommended core 17.5 cm2). If the core is W-shaped, the sectional area needs to be 1.4 times more, that is, 24.5 cm2.
In 1995, at the presentation of the family Mercedes-Benz SPRINTER representatives of the company announced that it starts an active attack on the European market with their trucks. According to the plans, within three years have been fully updated types of vehicles designed to operate on European roads. So, after “polutoratonny” SPRINTER van appeared “odnotonnymi” VITO.
By the middle of 1950-ies the main front-line reconnaissance aircraft was considered to be Il-28R. But the car, excellent in all respects, by the time against the backdrop of recent supersonic fighters became morally obsolete. Created at the same time, the Yak-25P, although outnumbered, “Il”, but the requirements of the military on the prospective scout is also not satisfied. In this situation, OKB A. S. Yakovlev proposed to develop a supersonic fighter-scout with engines AM-9F (RD-9F). The government and the military supported the proposal and in March 1956 was signed the corresponding decree.
At the initial stage of the Second world war, tasks of intelligence in the interest of armored and motorized units of the Wehrmacht did pretty well armored. Their use in this role was promoted as an extensive road network of Western Europe, and the absence of the enemy’s massive anti-tank defense (PTI).
For the rational use of weeds and grass-tops in gardens or allotments of their composted in pits or small towers. I’m doing this: throwing a wooden greenhouse in a box without a bottom size 2000X1000X400 mm.
