Klimov VK-106

The Klimov M-106 was an experimental liquid-cooled V12 piston aircraft engine intended for Soviet aircraft during World War II.

With the VK-105PF exhausting the potential of the M-105, Klimov prolonged its development into new VK-106 engine from 1941. Since air combat on the Eastern Front took place primarily at low altitudes (under 4,000 m {13,000 ft}), the new engine was built specifically for peak performance at those altitudes with a reduced compression ratio and a single-speed supercharger. Static testing was carried out from 27 October till 9 November 1942. Although reliable and easily installed in M-105-powered aircraft, VK-106 did not enter production because its cooling problems were not solved. Like M-105P, VK-106P could house an autocannon in the “vee” between the cylinder banks. Over 300 engines were built.

Klimov M-103

Klimov M-103 engine recovered from Tupolev SB wreck

The Klimov M-103 is a V12 liquid-cooled piston aircraft engine used by Soviet aircraft during World War II.

The M-103 was a further development of the Klimov M-100 engine that was itself a licensed copy of the French Hispano-Suiza 12Ybrs. It differed from both engines in a number of aspects such as increased compression ratio, increased supercharger ratio, increased rpm’s, strengthened cylinder blocks, a new crankshaft, and flat bottomed cylinders. Developed in 1936 it was ready for testing in October 1936. The first two models failed testing due to cracked cylinder blocks and the engine was resubmitted for testing in 1937. After passing its trials it was cleared for production in 1938 and 11,681 were produced until 1942 at its factory in Rybinsk. The M-103 was followed by the M-105.

Variants:
M-103A – 148mm rather than 150mm bore cylinders.

Klimov, Vladimir Yakovlevich

Vladimir Yakovlevich Klimov was born on 23 July 1892 in Moscow and studied at the Technical School Komissarovskom.

In 1918 he graduated from the Faculty of Mechanical Engineering of the Technical State University of Moscow NE Bauman and began his career in October of 1919 in Kolomna factory, an engineering company based in Moscow.

From July 1918 to 1931 he worked interchangeably as chief laboratory engineer, department head, assistant director of the automotive research laboratory of this factory which later became the Soviet Scientific Institute of Engines (NAMI).

After 1931 he became Head of the Department of Technical Control of gasoline engines of the Central Institute of Aviation Engines and at the same time, he worked as a professor at the Moscow Higher Technical School, the Lomonosov Institute and the Military Academy of the Force, Zhukovsky Aerial.

He was also head of the Engine Design Department at the Moscow Aviation Institute.

Vladimir Yakovlevich Klimov participated in the development of the first Soviet air-cooled star-shaped aircraft engines, the M-12, M-23, and others. In 1927 he created the first and most powerful engine of the time (approx. 650 kW (880 horsepower) the M-13 with liquid cooling for cylinders.

In the mid-1930s, it organizes the production of 12-cylinder M-100 engines, whose capacity was 30% more than that of similar foreign engines of the same size, at that time the M-103 series engine for bombers. “SB” designed by AA Tupolev and Arkhangelsk.

In 1935, Vladimir Klimov was appointed Chief Designer of the Rybinsk Engine Plant No. 26.

In August 1941, he worked designing high-power engines for Soviet aircraft destined to defend the USSR during World War II in a factory evacuated to Ufa.

The engines that Klimov had designed in the late 1930s and early 1940s (M-105, VC-105PF, EC-107, EC-108), were installed in Pe-2 dive bombers designed by VM Petlyakov and fighter jets designed by Yakovlev.

In the postwar period Klimov led the design and production of a wide series of jet engines.

During his work and research, Klimov developed and implemented a series of inventions and innovations in aircraft piston engines such as the closed liquid cooling system, the closed system with a special pressure air pump with two speed traction, advanced timing, mixed fuel feed systems in powerful and high-speed engines, and proposed a number of innovative solutions in the construction of the turbojet.

Klimov made a significant contribution to the development of lubrication theory, to the solution of balance piston engine problems, and other aircraft engine problems.

In 1947-1949 he created the first engines with internal centrifugal compressors for jet aircraft.

In 1951, on the basis of the English Nene engine, Klimov created the VK-1F – one of the world’s first turbojet engines equipped with an afterburner.

Vladimir Yakovlevich Klimov was a Deputy of the Supreme Soviet of the USSR from 1946 to 1950.

He reached the degrees of Major General in the USSR Air Engineering Service.

He was also an outstanding academic twice awarded as Hero of Socialist Labor (1940, 1957). Winner of four Stalin Awards (1941, 1943, 1946, 1949).

He died on September 9, 1962. He was buried in the Novodevichy Cemetery in Moscow.

In 2002, the name Klimov was given to a street in the Shevchenko district of Zaporozhye and a park called Academician Klimov already existed there.

Kitty Hawk Heaviside

Kitty Hawk revealed on 3 October 2019 that they had been secretly developing a single seat electric aircraft known as the Heaviside. The Heaviside features a front wing with two propellers, six propellers on the main forward swept wing, and a fairly conventional empennage. The propellers are all behind the wings and tilt downward for vertical flight. Later in October 2019, a software timing error lead to a crash of the Heaviside during flight testing.

Kitty Hawk Flyer

The Kitty Hawk Flyer flying car startup Google’s Larry Page is backing was first publicly demonstrated in April 2017. An aerospace engineer working for Silicon Valley company called Kitty Hawk piloted the Flyer above a lake about 100 miles north of San Francisco. It is an open-seated, 220-pound Flier with room for one person, powered by eight battery-powered propellers that howled as loudly as a speedboat.

The Flyer one-seat, propeller-driven vehicle is meant for a short flight across lake when you’re at the cottage, not commuting to work. During his test flight, Cameron Robertson, the aerospace engineer, used two joystick-like controls to swing the vehicle back and forth above Clear Lake. The flight, 15 feet above the water, circled over the lake about 20 or 30 yards from shore, and after about five minutes Mr. Robertson steered back to a floating landing pad at the end of a dock. The flyer is controlled by two handlebars and what looks like a giant touchscreen. It travels at up to 25 miles per hour at a max of 15 feet above water.

The vehicle is designed to fly above fresh water with two pontoons at its bottom. The prototype Kitty Hawk is showing off “looks and feels a lot like a flying motorcycle,” according to Cimeron Morrissey, who tested it.

They are flying under a special Federal Aviation Administration category for ultralight aircraft that does not require a pilot’s license and is intended for recreational flying in uncongested areas. To add an extra margin of safety, the Kitty Hawk engineers are sticking to flying over open water.

Kitty Hawk

The Kitty Hawk Flyer is just one flying vehicle being worked on by the Larry Page-backed startup. Page has reportedly invested more than $US100 million into Kitty Hawk and its other division, Zee Aero. Both organisations have registered to test a number of different aircraft, from gliders to sailplanes.

The goal of Kitty Hawk and Zee Aero is to one day reinvent personal transportation. Both divisions have roughly 100 employees combined. The CEO of Kitty Hawk is Sebastian Thrun, cofounder of Udacity and the father of Google’s self-driving car project.

The Kitty Hawk focus on over-water flights is intentional – it’s meant to reassure Federal Aviation Administration officials worried that unlicensed pilots will be flying over populated areas. The company wants to work with the FAA to enable more ambitious vehicles, but it would rather play it safe in the early stages.

Kinney Hot Rod Helicopter / HRH

This helicopter was designed, completed, and flown in one year, one month, one week and one day.
It’s named the Kinney HRH (Hot Rod Helicopter) because of the lack of doors and hood and an air cleaner from a dual quad setup. The helicopter is small enough to fit in a home garage, and the counter-clockwise rotation of the Waitman blades is the same as standard America helicopters.
The HRH uses a 165 hp 4-cycle, 4 cylinder Subaru. It employs a computer-controlled fuel-air mixture, redundant fuel pumps, and multi-port fuel injection. It uses regular gasoline. The rotor head provides full cyclic and collective pitch, with an electronic system for maintaining rotor speed. The main blades are constructed of composite materials and the tail rotor is shaft driven.
The fully enclosed composite cabin features a fully equipped panel with both digital and analog instrumentation; a vinyl-covered seat with a “crumple-zone” support; a 4-point aircraft seat belt; and a tinted polycarbonate windshield. Addition of doors and a catalytic heater provide year-round comfort.
The powder-coated airframe is formed of aircraft-grade 4130 chromemoly steel, the primary structure both welded and bolted together with aircraft hardware. Most of the aluminum parts are black anodized.

Kinney

Bob Kinney, designer/builder of the HRH, considers himself a practical “electro-mechanical applicationist.” Bob was born in a small town in Connecticut where, as a young boy, he and some friends would visit a nearby factory that was manufacturing curious rotary-wing machines. Looking back, Bob is convinced that the man with the distinctive Russian accent that continually chased him and his friends away from that factory was Igor Sikorsky—father of the modern helicopter—and only later understood that those curious machines were helicopters.
