Bellanca 31-42 Senior Skyrocket / 31-55A Senior Skyrocket

31-55A Skyrocket

The 31-55A Senior Skyrocket is generally similar to the Pacemaker but carries a crew of two and six passengers. The Skyrocket was first produced in 1930, and was built with a variety of radial engines in the 450-500 hp range prior to World War 2.

They were built post-war under licence in 1946-7 by North-West Industries Ltd in Canada. Powered by a 500 hp Pratt & Whitney Wasp S3H1, it is otherwise identical to the Model 31-42 Skyrocket of 1935.

Bellanca 19-25 Skyrocket II

Skyrocket II

The Bellanca 19-25 Skyrocket II is a prototype light plane built in 1975 by Payne Engineering Company. The aircraft design was the result of Giuseppe Bellanca’s son, August attempting to revive the original Bellanca company with an all-new design to prove that proper composite design could take advantage of a 1940’s NACA laminar flow airfoil. Designed over a sixteen year period and design and constructed over two and a half years, the project was begun on Long Island, New York and later transferred to Huntington, West Virginia.

The Skyrocket II is a six-seat, low-wing cantilever monoplane of conventional configuration with retractable tricycle undercarriage. The SkyRocket has an aluminum honeycomb, molded into a half inch thick skin. The Bellanca uses pre impregnated glass cloth kept frozen in a freezer until ready for use and then laid in the mold, where it softens. When sandwiched in honeycomb, it is cured in an oven for an hour and a half at 250 deg F. There are left and right molds for the fuselage and for the vertical tail, and top and bottom molds for the wings and horizontal tail. The wing is buttressed by a pair of glass spars fastened in the fuselage floor by metal bolts.

Skyrocket III

The inside of the fuselage shell discloses three bulkheads of plastic, and an inte¬gral part of the monocoque structure, once the fuselage halves are joined.

Wet wings hold 180 US gallons of 100 octane for a planned max fuel range of 1,485 nm at a 75¬% cruise. The expected stall speed, with gear and flaps down, is 56 knots.

$340,000 was raised from 20 friends of the Payne’s to construct this plane from August Bellanca’s design drawings in the 1974-1976 time span.

August Bellanca was the designer. John P Harris was the construction engineer and the test pilot for all flights through 1978, including the 5 FIA world record runs. Henry E Payne was the chief director and facility provider for the project. These three were the key group that produced this prototype. They are all deceased within five years before 2007.

The test pilot for this new prototype was John P. Harris. Within months of its first flight, the prototype claimed five FAI world airspeed records for an aircraft in its class, all of which still stand in 2007. The aircraft attracted the attention of NASA, which conducted an aerodynamic analysis of the design, in order to investigate natural laminar flow as a factor of its high performance.

The six place SkyRocket II is envisioned by its builders as the fastest piston single in commercial general aviation. They attempted to raise three to five million dollars to get the plane certificated. There were plans also for a twin-engine version of the Skyrocket. The plan was to build 100 units per year and sell each for $200,000 including the estimated $100,000 product liability insurance premium. The time frame for raising money, 1976-1979, included 15% to 20% interest rates. The money could not be raised so the project was discontinued. August Bellanca took the plane to Delaware and tried the kit plane concept and other attempts to manufacture the plane. Despite its advanced design and exceptionally good performance, it never achieved certification or entered production.

AviaBellanca Aircraft Corp announced in 1998 an advanced derivative of the SkyRocket, the AviaBellanca 19-25 Skyrocket III. Incorporating carbon fibre/Nomex foam structure and a 435 hp Continental GTSIO-520, the Skyrocket III has a 0.0155 drag coefficient.They claim a kit could be assembled in 3500 hours and take from 325 to 500 hp.

Bellanca Aries T-250 / Anderson & Greenwood AG-51

Ben Anderson, Marvin Greenwood and their associates conceived a sophisticated airplane, and in 1971, the preliminary design of the four place AG 51 was completed.

One AG-51 prototype was built in 1973, N51AG c/n 0001, later redesignated as the first Bellanca T-250 Aries It received Approved Type Certificate A11SW. That aircraft (which the FAA claims was built in 1976) was apparently re-registered as N251AG. The design won full FAA certification on July 8, 1976.

Two more examples built as Bellanca T-250 Aries types, under the same Approved Type Certificate. C/n 0003-80 is N250DJ and c/n 0004-80 is N77CT.

C/n 0002 has never been mentioned and c/ns 0005 to 0007 were reserved but not built.

Anderson, Greenwood’s AG 51 may be transformed into the Bellanca Aries T 250 at the stroke of a pen. The two companies had reached an agreement in principle, subject to negotiations as well as other conditions including outside financing. Under the agreement, Bellanca would manufacture the airplane at its Alexandria, Minnesota facility and would handle marketing as well. Bellanca would have a new mod¬el and the Aries T 250 a home in which to be built and someone to market it.

The Aries T¬250 is a metal airplane, powered by a 250 horsepower carbureted Lycoming, designed for the best combination of production efficiency, performance and good handling qualities.

The main landing gear tread is narrow. With a T tail, the wings are constant chord with a low aspect ratio. A T 250s can lift a gross of 3,150 pounds, and the prototype would fly with full tanks (76 gallons), four 170 pound people and 99 pounds of luggage.

An agreement giving Bellanca Aircraft exclusive production rights to the Aries T-250 single engine retractable expired at the end of 1977. According to Bellanca President James Callier, Anderson, Green-wood Aviation Corporation which controls the rights to the airplane and has pumped $2.4 million into Bellanca since 1976 – found it unwise to continue an agreement when there were no immediate prospects that would allow Bellanca to begin production.

Bellance 14-19 / 17-30A Viking / 17-31 / 17-31 Super Viking

Viking

A development of the Cruisemaster, the Viking wing is made of Sitka spruce and mahogany, crafted in a separate wing plant. The fuselage is welded steel tubing covered with Dacron. It is all as durable as aluminum, and Bellanca feels that this unique method of construction is one of their major assets.

Bellanca 260

The Bellanca 260 was introduced in 1964 and produced through 1967. Built of wood and fabric, only 105 were built before production switched entirely to the Viking 300.

In 1967, a 300 hp Continental IO 520 D installation transformed the Bellanca Model 14 design into a Viking. Somewhere along the way, Vikings become Models 17 30A, but the overall aerodynamic design is true to the genius of Giuseppe Bellanca.

Viking 300

There are three 300 hp engine options for the Viking: a Continental IO 520 K, a Lycoming IO 540 K1E5 and the Ra¬jay turbocharged version of the Lycoming. The Viking is 3,325 pounds at gross, with an empty weight of 2,225 pounds. When a Viking is topped with 450 pounds of fuel, 75 pounds of options and 340 pounds of people, it’s easy to see how most of the 1,100 pound useful load can quickly disappear. The baggage compartment capacity is billed as 186 pounds, although it looks too small for what that weight of luggage would amount to. There is also a tube-like container running back from the baggage area toward the tail that is designed to hold 20 pounds of long equipment, such as skis or fishing poles.

Bellanca 14-9 Cruisair

Cruisair 14-13

The original Model 14 9 Bellanca Junior, later renamed the Cruisair, started life with a 90 hp LeBlond radial engine and 140 square feet of wing area. Later versions, such as the Models 14 13 and 14 14 developed in the early ’40s, had Franklin powerplants and a healthy 161 square feet of the famous Bel-lanca B airfoil. In 1952, a 190 hp Lycoming was mated to the Cruisair’s tubular steel fuselage and the Model 14 19 Cruisemaster was born. Seven years and a new manufacturer later, the design was resurrected, modified to accommodate the 260 hp Continental IO 470 and designated the Model 14 19 3. Although a tri gear and a swept vertical stabilizer characterized subsequent Bellanca evolutions, the wing, with its Sitka spruce spar, mahogany skin and 161 square feet, remained basically unchanged except for some strengthening to accommodate the higher gross weights of the updated aircraft. In 1967, a 300 hp Continental IO 520 D installation transformed the Bellanca design into a Viking.

14-19-3 Cruisair

14 Cruisemaster
A low-wing, retractable four-seat monoplane with a good reputation for speed and lifting ability. The wooden wing tended to keep sales down and only 700 or so were built before the Cruisemaster design was updated with tricycle gear, swept fin, and a new name the Bellanca Viking.
Northern Aircraft Inc purchased from Bellanca all rights, jigs and tooling for the Bellanca 14-19 Cruisemaster four-seat lightplane. The Bellanca Model 14 was one of the classic lightplane designs, since built by several manufacturers. First production of the Northern Cruisemaster started in October 1956. Northern also supplied spares, support and modification kits for Republic Seabee amphibians after a merger with the American Aviation Corporation.

Bellanca 28-70 Irish Sweep

Col James Fitzmaurice, a colonel in the Irish Air Force entered a Bellanca 28-70 “one off’ named Irish Sweep, in the London Mebourne Centenary Air race in 1934. The aircraft was built to his order and designed by Al Mooney of Mooney aircraft fame, who worked for Guiseppe Bellanca in the Delaware factory at the time. This was M8 in Mooney’s personal model numbering and a P&W Wasp radial of 825 hp was fitted, giving the Bellanca the best power/weight factor of all entries. The com¬mittee refused to allow Col Fitzmaurice to compete with the aircraft’s ‘all-up’ weight of 8,000 lbs.” The full weight had a restricted certificate issued by the US Government which, at the time, did not belong to the ICAN, the interna¬tional controlling body. The Irish entry was withdrawn at the last minute.

Engine: P&W Wasp, 825 hp.

Bellanca Aircruiser 66 / P-100 / C-27

Bellanca C-27C Airbus

The Bellanca Aircruiser and Airbus were high-wing, single-engine aircraft built by Bellanca Aircraft Corporation of New Castle, Delaware. The aircraft was built as a “workhorse” intended for use as a passenger or cargo aircraft. It was available with wheels, floats or skis. The aircraft was powered by either a Wright Cyclone or Pratt and Whitney Hornet engine.

Bellanca P-100 Airbus

The first Bellanca Airbus was built in 1930 as the P-100. An efficient design, it was capable of carrying 12 to 14 passengers depending on the cabin interior configuration, with later versions carrying up to 15. In 1931, test pilot George Haldeman flew the P-100 a distance of 4,400 miles in a time aloft of 35 hours. Although efficient, with a cost per mile figure of eight cents per mile calculated for that flight, the first Airbus did not sell due to its water-cooled engine.

The next model, the P-200 Airbus, was powered by a larger, more reliable air-cooled engine. One version (P-200-A) came with floats and operated as a ferry service in New York City, flying between Wall Street and the East River. Other versions included a P-200 Deluxe model, with custom interiors and seating for nine. The P-300 was designed to carry 15 passengers.

The final model, the “Aircruiser,” was the most efficient aircraft of its day, and would rank high amongst all aircraft designs. With a Wright Cyclone air-cooled supercharged radial engine rated at 715 hp, the Aircruiser could carry a useful load greater than its empty weight. In the mid-1930s, the Aircruiser could carry 4,000 lb payloads at a speed of between 145 and 155 mph, a performance that multi-engine Fokkers and Ford Trimotors could not come close to matching.

C-27A C/N 721

The Airbus and Aircruiser served as both commercial and military transports and in total 23 were built.

In 1934, United States federal regulations prohibited single-engine transports on United States airlines, virtually eliminating future markets for the Aircruiser. Where the workhorse capabilities of the Aircruiser stood out was in Canada. Several of “The Flying Ws”, as it was commonly dubbed in Canada, were used in northern mining operations, ferrying ore, supplies and the occasional passenger, into the 1970s.
