Guimbal Cabri G2

The Guimbal Cabri G2 is a two-seat single-reciprocating-engine-powered light helicopter. The two-seat Cabri G2 light helicopter was designed by Bruno Guimbal, a Eurocopter engineer, and the prototype (F-PILA) made its first flight at Marseille-Marignane in April 1992.

Guimbal Cabri G2 Article

Powered by a 150hp Lycoming, the main structure is carbon composite construction, and it uses a three bladed soft-inplane main rotor with carbon composite blades. The tail rotor is a fenestron design using seven injection moulded blades. Energy attenuating carbon composite seats of Guimbal’s own design are installed. The helicopter has conventional unassisted flight controls and largely conventional analogue instrumentation but uses its own design of electronic monitor for all engine functions.

An STC embodied on the engine is held by Guimbal and comprises a Plasma electronic ignition with variable timing to replace the RH retard-capable magneto, and also a compact oil filter housing.

Development continued at Aix-en-Provence with restricted DGAC certification being issued on 18 April 1994.The helicopter is the first light helicopter to be type certificated (Type Certificate R.145) by EASA against CS27.

Type Acceptance Certificate No. 11/21B/20 was granted on 22 June 2011 by New Zealand CAA.

Goodyear GA-400R Gizmo

In 1954 Goodyear Aircraft Corporation produced a single-seater helicopter intended for the tactical requirements of transporting one man only. This single-seater open-frame ultra-light helicopter, designed by Paul Ziegler, is powered by a water-cooled, two-cycle engine driving the rotors through a belt and pulley arrangement. The main rotor consists of two laminated blades balanced about the feather axes and mounted in a steel hub underslung from a teetering hinge. The airframe is constructed from welded tubing, and the landing gear is formed of parallel aluminium skids.

The first flight took place on 9 May 1954 (N62N).

Designed by Paul Ziegler, this prototype was designated GA-400R Gizmo, with the pilot seat on the forward frame, a narrow tailboom with a tail rotor and the 32hp Mercury 55 engine mounted amidships and driving a two-blade main rotor. It was followed by the GA-400R-2 and GA-400R-3 (N69N and N53A) which were powered by a 38hp Johnson two-stroke engine. The GA-400R did not progress beyond prototype stage.

Gluhareff EMG-300

Mr. Gluhareff pioneered the use of liquid propane as a fuel for jet engines and a series of ultra-light portable one-man-helicopters, MEG-1X, MEG-2X and MEG-3X which were designed and built by his own company, Gluhareff Helicopters Corporation. All of which were powered by the G8-2 Pressure Jet Engine on the blade tip and test flown by Eugene M. Gluhareff.
In 1972 Mr. Gluhareff returned to research and design under his own company name of EMG Engineering in Gardena, California. There he continued his work on the G8-2 Pressure Jet Engines which ranged from five pounds of thrust to 700 pounds of thrust.
Mr. Gluhareff designed, built and tested his own one-man tip jet helicopter, the EMG-300 in the early 90’s. Its successful test flight marked the realization of Mr. Gluhareff’s lifelong dream to design what he called a “Flying Motorcycle”.
The EMG-300 was his last design before his death in 1994, it had completed an initial series of test flights, but was not completely tested at the time of his death.

Gluhareff

Eugene M. Gluhareff was born in St. Petersburg, Russia in 1916 immigrating to the United States with his family via Finland in the early 1920’s.
An Aeronautical Engineer graduate of Rensselaer Polytechnic Institute in Troy, New York, he is a jet engine and helicopter designer and inventor. His extensive experience was acquired over many years of association with leading companies in the fields of design, research and development.
He has been a part of helicopter development since its beginning in 1940 with Sikorsky Aircraft Corporation in Bridgeport, Connecticut as a primary design engineer and project engineer. He worked directly under Mr. Igor I. Sikorsky and Mr. Igor A. Sikorsky, Chief of Aerodynamics. It was there he invented and developed the Pulse Jet Engine, a one-man single bladed jet helicopter which he test flew himself and also a Delta Wing Convertiplane for the United States Airforce.
In 1950 he moved to California and joined the American Helicopter Company in Manhattan Beach as a project engineer on a pulse jet powered helicopter (Top Sergeant). He was promoted to Chief of Preliminary Design and there designed the XH-26 One-Man-Jet Helicopter for the U.S.A.F.. Following this term with American Helicopter, he worked with Rotorcraft Corporation in Glendale, California as Design Engineer and was engaged in the redesign of a rocket powered one-man-helicopter for the U.S. Navy.
Eugene Gluhareff established a development company in 1952 to carry out research into pressure-jet powered light helicopters.
It was during this time that Mr. Gluhareff pioneered the use of liquid propane as a fuel for jet engines and a series of ultra-light portable one-man-helicopters, MEG-1X, MEG-2X and MEG-3X which were designed and built by his own company, Gluhareff Helicopters Corporation. All of which were powered by the G8-2 Pressure Jet Engine on the blade tip and test flown by himself.
In the early sixties, he was employed by the U.S. Navy at the Naval Ordinance Test Station in China Lake, California as an Aerospace Engineer FS-14 and Project Engineer on Rotary Drones. In 1964 he joined the Douglas Aricraft Company, Missile and Space Division as Design Engineer Scientist on the S-4 stage of the Saturn Rocket used on NASA’s Apollo Project. During this time he participated in the launching of four Saturns. Later he worked at McDonnel Douglas Aircraft in Long Beach, California as a Senior Design Engineer in Advanced System for Special Projects researching and testing rocket engines. There he became a specialist in the design of rocket stabilization systems for ejection seats and capsules.
In 1972 Mr. Gluhareff returned to research and design under his own company name of EMG Engineering in Gardena, California. There he continued his work on the G8-2 Pressure Jet Engines which ranged from five pounds of thrust to 700 pounds of thrust. To further promote the study of aerodynamics and jet propulsion, Mr. Gluhareff designed and placed in universities throughout the country the Gluhareff GTS-15 Teaching Stand. He also had the G8-2 Pressure Jet Engine displayed as a working exhibit in the California Museum of Science and Industry in Los Angeles. The G8-2 Jet Engine had the honor of gracing the cover of Mechanics Illustrated in May of 1973 and again in January 1975 in the Jet Powered Go-Kart.
Mr. Gluhareff designed, built and tested his own one-man tip jet helicopter, the EMG-300 in the early 90’s. Its successful test flight marked the realization of Mr. Gluhareff’s lifelong dream to design what he called a “Flying Motorcycle”. He had several patents issued and applied for, for his inventions. Some of which are the G8-2 Jet, Valveless Pulse Jet, Portable and One-Man Helicopters, Flying Platform, Rotorcar, Convertiplane, Rocket Stabilization Unit and others.
