Light and Small Helicopter Competitors

CoaX will have unique advantages in the light and small helicopter market.

No Tail Rotor

Optional Diesel and Gas Turbine power plants

But what is CoaX competing against? Here is a list of some of the small, light and ultralight helicopter competitor aircraft.

Robinson R22 Small Helicopter
The R-22 is a single-engined helicopter with a semi-rigid two-bladed main rotor and a two-bladed tail rotor. The main rotor provides a teetering hinge and two coning hinges. The tail rotor provides only a teetering hinge.
dis_r22_yellow
The normal production variant has skid landing gear. The Mariner version provided floats. Wheeled gear is not available.

The basic structure is welded chromoly steel tubing. The forward fuselage is made of fiberglass and aluminum with a Plexiglas canopy. The tailcone, vertical and horizontal stabilizers are aluminum. It has an enclosed cabin with side-by-side seating for a pilot and passenger. The doors may be removed for flight, and are often done so for photographic flights, interior cooling in high temperatures, or a 10.4 lb weight saving.

The first version was produced as the R22, followed by the R22 HP, R22 Alpha, R22 Beta and R22 Beta II. Superficially, the aircraft appear similar. The R22 HP was fitted with a 160 bhp Lycoming 0-320-B2C engine, an increase of 10 bhp (7.5 kW) over the original R22. The landing skid assembly on the R22 Alpha was modified by extending the rear struts, giving it a slightly nose-down attitude on the ground and better matching its attitude in a low altitude hover with two people onboard. The R22 Beta added an engine speed governor (optional), rotor brake and auxiliary fuel tank (optional). The battery was moved from below the instrument cluster to the engine compartment for better balance. It has been offered as an instrument trainer version, with optional fixed floats as the R22 Mariner, and other special configurations for police work, electronic news gathering, and so on. The R22 Beta II added a Lycoming 0-360 engine, remade of lightweight materials and derated for sealevel operation. It allows greater altitudes for hovering in and out of ground effect (HIGE/HOGE). The R22 Beta II also made the engine speed governor standard and included a “carb heat assist” which correlates adding carb heat with decrease in collective control. Only the basic skid style is currently being sold. The R44 is available as the Clipper with floats, and as police and electronics news configurations.

Sikorsky S-300 Hughes/Schweizer 300 series S-300C Small Helicopter
dis_800px-Schweizer269C-G-BWAV
In 1955, Hughes Tool Company’s Aircraft Division (later Hughes Helicopters) carried out a market survey which showed that there was a demand for a low-cost, lightweight two-seat helicopter.[1] The division began building the Model 269 in September 1955. The prototype flew on 2 October 1956,[3] but it wasn’t until 1960 that the decision was made to develop the helicopter for production.[1]

On 9 April 1959, the 269 received certification from the Federal Aviation Administration (FAA) and Hughes continued to concentrate on civil production. With some design changes, deliveries of the Model 269A version began in 1961. By mid-1963 about 20 aircraft were being produced a month and by the spring of 1964, 314 had been built.[1] Hughes had successfully captured a large portion of the civilian helicopter market[3] with an aircraft that would prove itself popular in agriculture, police work and other duties.
Model 300
Schweizer 300C
Schweizer 300CB

In 1964, Hughes introduced the slightly-larger three-seat Model 269B which it marketed as the Hughes 300. That same year, the Hughes 269 set an endurance record of 101 hours. To set the record, two pilots took turns piloting the aircraft and hovered in ground-effect for fueling. To ensure no cheating, eggs were affixed to the bottom of the skid gear to register any record-ending landing.[3]

The Hughes 300 was followed in 1969 by the improved Hughes 300C (sometimes 269C), which first flew on 6 March 1969 and received FAA certification in May 1970.[1] This new model introduced a more powerful 190 hp (140 kW) Lycoming HIO-360-D1A engine and increased diameter rotor, giving a payload increase of 45%, plus overall performance improvements.[4] It was this model that Schweizer began building under license from Hughes in 1983.[5]

In 1986, Schweizer acquired all rights to the helicopter from McDonnell Douglas, which had purchased Hughes Helicopters in 1984. After Schweizer acquired the FAA Type Certificate, the helicopter was known for a short time as the Schweizer-Hughes 300C and then simply, the Schweizer 300C. The basic design remained unchanged over the years, despite Schweizer making over 250 minor improvements.
Derivatives

Between Hughes and Schweizer, and including foreign-licensed production civil and military training aircraft, nearly 3,000 units of the Model 269/300 have been built and flown over the last 50 years. Schweizer continued to develop the Model 300 by adding a turbine and redesigning the body to create the Schweizer 330. Further developing the dynamic components to take greater advantage of the power of the turbine engine led to the development of the Schweizer S-333.

Schweizer was purchased on August 26, 2004, by Sikorsky Aircraft. The Schweizer 300 models fill a gap in the Sikorsky helicopter line, which is known for its medium and heavy utility and cargo helicopters.[6]

Heli-Sport CH-7 Ultralight, Kit Built, Helicopter
dis_800px-CH7-Kompress
In 1989 EliSport, who became Heli-Sport in 1997, bought the rights to the Cicare CH-6, a small single seat open cockpit helicopter designed in Argentina by Augusto Cicaré. It was developed by Josi and Claudio Barbero and, with the help of the sports car designer, Marcello Gandini who produced a new, enclosed, cabin, marketed from 1992 as the CH-7 Angel.[1] Its commercial success led to a tandem two seat version with a stretched cabin and bigger engine named the CH-7 Kompress and, in 2005, a further refinement designated the CH-7 Kompress Charlie.[1]

The piston engined CH-7 ultralight series use the traditional “penny-farthing” layout with two bladed main and tail rotors. The main rotor is formed from composites and is a teetering, semi-rigid design with 6° of twist. The tail rotor is aluminium. The pod and boom fuselage has a glass fibre cabin built on a steel tube frame, with a long transparent forward opening canopy. The steel frame also carries the engine, semi-exposed behind the accommodation and connected to the main rotor shaft by a belt drive. A slender aluminium boom, strengthened by a pair of long struts to the lower fuselage frame, carries both the tail rotor and swept fins. The upper fin is topped with a short horizontal tailplane, with small endplate fins, and the lower one ends with a tailskid. The CH-7 uses a simple aluminium skid undercarriage, which may be fitted with small wheels for ground handling or multi-tube inflatable floats for flying off water. In this last form the CH-7 is called the Mariner. The Kompress Charlie has faired, wide chord carbon fibre skid legs.[1]

The Kompress and Kompress Charlie are sold in kit form for home assembly, the manufacturers quoting a 200-hour building time. A fast build kit, with more components pre-assembled, is claimed to need 85 hours.[1]

The Kompress series may be fitted with a hook for lifting loads of up to 100 kg (220 lb), or fitted with spray bars for agricultural work.

Mosquito Ultralight Kit Helicopter
dis_IMG_3425
dis_Mosquito
The Mosquito is one of the worlds lightest manned Helicopters that has been designed and developed over the past 10 years to deliver performance, reliability and easy of flight. Ken Armstrong of Kit Planes Magazine said that the “Mosquito is convincing – it’s as close as you can come to real flying with almost no means of support, and the view is at least as good as a bird”. He also said that “Flying the refined Mosquito Ultralight was the most fun I’ve ever had with a Helicopter!”.

Frame:
The Mosquito frame is made up of Aircraft Grade 6061-T6 aluminum and utilities a simple triangulated structure with straight tubing throughout to maximize strength, reduce weight and simplify construction. The additional use of a Carbon Fiber tail boom and support struts adds to the Mosquito’s structural rigidity and further improved its power to weight ratio.The Mosquito’s tripod legs are equipped with small skid pads to help reduce lateral movement during engine run-up to lift off stage. Ground handling wheels are also available to easy ground transport.

Engine:
The Mosquito is powered by Compact Radial Engine’s – MZ202, 60-hp, a two cycle, two cylinder engine with the highest power to weight ratio on the market today. This engine employes Reed Induction which yields a very flat torque curve ensuring power is delivered constantly over the required operating range. The MZ202 also has a lower operating speed of 6000 rpm when compared to other engines with similar power range that typically operate at 6500 to 7000 rpm resulting in less stress on the engine and improving reliability.The complete engine package only weighs 69 pounds and comes with a 180-watt alternator that provides power to run the electrical system which also features and an electric start system.

Power Train:
The primary reduction is bolted directly to the engine. A centrifugal clutch on the engine crankshaft permits start up of the engine without the load of the rotor. Power is transmitted from the clutch to the driven pulley of the reduction through an HTD cog belt, one of the highest power to weight ratio power transmission methods available. The driven pulley houses the sprage clutch which permits the rotor to over speed the engine during auto-rotation.

Rotorway Light Kit Helicopter
dis_talon2
“The A600 Talon is the first of a new generation of RotorWay machines, built on a tradition of delivering on our promises,” said CEO Grant Norwitz, as the machine went through its paces for the cameras early in the Arizona morning of the fifth of July. “With our new facilities, our new programs, and our commitment to establishing an atmosphere in which certification of future designs will be fulfilled, the Talon exemplifies the spirit of RotorWay: strong traditions and fresh thinking.”

The A600 Talon is a top-to-bottom redesign, incorporating many customer-initiated requests, advanced electronics, engineering, and convenience items. The cockpit is now all-glass, using the MGL Avionics system. The completely redesigned and tuned FADEC system now has a secondary FADEC as a clone of the primary. Any failure of the primary unit will be imperceptible to the engine informing the pilot on the MGL display. The 162’s primary drive chain is replaced by a heavy-duty cog belt for ease of maintenance and longevity.

The useful load is 535 pounds, including a 100-pound luggage compartment. Economy cruise is a practical 90mph and fast long-distance cruise has already been demonstrated at 100 plus, with the doors off! The landing gear is 10 inches wider, 10 inches longer, and 7” higher than its smaller predecessor the Exec 162. This enables improvements in strength and stability, while offering greater accessibility underneath for the optional accessory luggage pod.

Process controls and designs with the new Talon’s manufacture at Rotorway’s new factory, are specifically aimed at the company’s plan to develop and deliver a certified helicopter. The A600 Talon is to be built in the new facility, on the new line, under the new processes that are being set up and proven to enable the certified machine to follow as early as 2011 in the United States. These new processes, materials, and documentation on the experimental, owner-built A600 Talon are designed to mesh into the processes and controls to be used on the future certified machine. The result is that the Talon will be built to type certified standards, of certified materials and with all the processes and controls expected of a manufacturer with the pedigree of RotorWay – and yet will be sold at kit prices.

The RotorWay success story is the culmination of over 4 decades of perseverance, progress in design and engineering development. Today RotorWay continues to be driven by individuals that believe in the company’s mission — To provide the rotorcraft customer worldwide with a safe, affordable way to experience their dream of rotary wing flight.
