GLIDER OR GLIDER? Unpowered gliding flight has long attracted man. It would seem that what is easier is attached to the back wings, jumped down the mountain and … flew. Alas, many attempts to rise into the air, described in historical Chronicles, has led to success only in the late nineteenth century. The first glider was a German engineer, Otto Lilienthal, glider balance created is very dangerous to fly the aircraft. In the end, the glider of Lilienthal killed its Creator and brought a lot of trouble enthusiasts gliding flight.
SCHOOL OF AIRCRAFT (PART 5)
In two decades of Windsurfing technical equipment of the sport has undergone many changes. Through the efforts of enthusiasts Board sailing from clumsy boats, is a conventional surf surfer with a sail attached, turned into a projectile, embodying the latest achievements of Aero – and hydrodynamics and constructed of materials that previously were used only in aerospace engineering, for example, carbon fiber and Kevlar.
Only four minutes, the athletes rakatomalala to prepare for the start. How much do you need to keep up with the time flying at the competition as if one moment: to install the model on the guide pin. To connect Elektrostal, to determine the atmospheric conditions at this point and calculate the direction of flight, accurately to execute the command “start!”.
Continuously growing speed racing car, top athletes, designers are finding new technical solutions that increase the speed of avtopoligon, new methods of forcing-engines, better ways of suspension. And as a natural result — new records. So, last year, the master of sports of the USSR, Leningrad A. Medvedev at the all-Union competition “Match the fittest” broke the record of the Soviet Union — his polutorametrovy was racing the distance at a speed of 223,880 km/h!
Today, we first introduce you to the most massive representatives of the ship-class F1-V. This high-speed RC ships with engines working volume of 10 to 15 cm3. One of the most successful developments in this subclass is the model A. Baidebekova.
The editors have received many letters on the publication of “Biogas: and warms, and cooks” (see “M-K” № 1, 1987), based on the materials of the Romanian journal “Technium”. Of readers was attracted by the subject and documented in the design. Many are interested in the details of the devices bostanova, asking how to make the individual nodes. Further clarification and recommendations for possible solutions to the structural elements gives our consultant engineer P. Zach.
The design sports a model rocket with a streamer class Б6А traditional. Athletes rocketmodeler repeatedly noted that models in this class closer to a kind of optimum. Now much depends on the quality of manufacture and Assembly of their components. The proposed model is performed based on these requirements, can show good results in competitions.
For his bike, I chose a folding bike “Desna-2” In model-849 with smaller wheels (20 X 1.75). To install it on the motor, did some fine-tuning.
The laboratory experimental machines Orlowski city Palace of pioneers named after Yuri Gagarin a lot of interesting and original works. At the regional exhibitions NTTM they attract the attention of visitors of all ages. And no wonder! The search range of the young designers wide: training glider and walking robot, a flying car and microtracker. With every new car the guys are in the way of true researchers: outlining the purpose, carefully studying the existing experience, then, given their own capabilities, define the technical requirements to future design and finally design and build it. So was born a twin recumbent LEM-05 (laboratory of experimental machines, 5-I model), the creation of the device, which says the head of the laboratory of engineer V. I. Borodec.
