the Conversation today will focus on the sailboat of a new type — light weight, affordable and versatile vessel-trimaran, which portable travel paddle with a soft shell. The merits of such a lot of trimarans, and one of the most important is the low cost of the kayaks and additional sailing arms. In addition, such a vessel do not require hospital car Park on the shore — enough and the mezzanine in the apartment; to deliver the same trimaran to the water is possible even on public transport, not to mention the train.YOUNGER BROTHER
A mini-tractor, which is presented to the readers of the journal “modelist-Konstruktor”, is the third built by me. His frame is “broken”, consists of two articulated half-frames, as in the heavy tractor T-150. A node of articulation serves as a node (or mechanism) of rotation. A used engine from a motorcycle “Ural”, equipped with a Read more…
Kayak in the open sea… Not even if is”? Well, it depends on what kind of kayak. “Petrel were” — the lightest boat, the description of which is offered to your attention, is not afraid of windswept expanse or sea waves. The survivability of the ship is ensured by its design. Add to this the accuracy on the course and the safety for crew and cargo in extreme weather conditions. In spite of the elongated body, the boat easily, as sailors say, “clears” from the wave, and has a good “viable” even in cool water shafts. All control systems work quickly and reliably, and steering is effective in any maneuver.
With all its advantages of an inflatable boat of any design has the same General disadvantages: Shorty wislica, turtle speed and bad handling. From all of them at once we managed to get rid of, adapting your boat “Dive-4” under sail: with him she became and the faster and more manageable. And actually upgrading was quite simple and compact, that is blended with the amenities characteristic of inflatable boats.
Wheeled Buer, beach sailing, sand yacht, metromobile… All these terms refer to the same Tina of vehicles using the movement force of the wind. Designs of such “petroholod” — a great many, from year to year are added up — three wheels and four, with Latin sail and with the Bermuda arms, hard planes, reminiscent of an aircraft wing, and even with a horizontally positioned fan-like impeller anemometer.
No matter how much we have seen this picture every time it will amaze and fascinate with their uniqueness: easy flick of a switch — and just as silently as it stood, the car started and ran, picking up speed. The heart of this design — the electric motor. To it again drawn the attention of automakers and even in connection with energy problems. Do not stand aside from these searches, and Amateur designers, some of their works have been highlighted on the pages of our magazine. Today we introduce the electric car of formula D — baby, built by our reader A. Logvina from the city for his daughter called “Alyonushka”.
I’m a physics teacher and a faithful subscriber of the journal “modelist-Konstruktor”. Write and assemble a binder began while still a student in 1980. Thanks to him I became one of those whom the people called “avid homebrew”. One of my first designs was a mini-tractor “Gerez”, built together with the guys from the circle of technical creativity, which was led by part-time. Mini tractor took first place in the Republican review of technical creativity of pupils. Engine — motorized С3Д installed across; the gearbox from the car GAZ — 51, rear axle — from “UAZ”, shortened. At the mini-tractor 20 gears: 16 forward and 4 backward speed from 1 to 52 km/h. Its own mass of 500 kg can pull the truck with load up to 1200 kg.
Practice Amateur autocostruzione, including my personal, shows that wagon layout with the use of wheels with tyre size 5X10 (motorized С3А) provides a very convenient and rational design of little micro-car. That is my “Mikrus”. It is stable, holds the road well, speeds up to 90 km/h the engine under the driver seat and the passenger increases the useful volume, makes the body more succinct. The interior is spacious, seats are arranged, which is convenient for overnight stay and rest. One cannot underestimate the capacious trunk: there is, for example, you can install a baby carriage, not looking. In the right corner of the trunk easy to install the battery, and in the bottom of the fuel tank from the car ZAZ-966. Made for the base, they both increase the load on the rear axle, which improves traction of the drive wheels. And convenient access to the engine: the hood folds with the seat, driver and passenger; repairing and explore without leaving the salon. For transportation of bulky goods — TV, washing machine, fridge — enough to move the back seat forward and fold the seatback or delete it. Get a small truck.
It is no exaggeration to say that the main airframe-the autogyro is the rotor. From the correctness of the profile, from weight, precision, alignment and strength depend on the performance of the gyro. However, non-motorized vehicle on tow behind the car rises only 20 – 30 m. But the flight at this altitude requires mandatory compliance with all previously stated conditions.
