Aerophysics VZ-7 / Curtiss-Wright VZ-7

Soon after the U.S. Army ordered two VZ 7 aerial jeep research prototypes from the Aero¬physics Development Corporation, the company was absorbed by Curtiss Wright Corporation and became its Santa Barbara Division.
The VZ 7 was originally designed as a ducted ¬fan type, like the VZ 6 and VZ 8, but it flew only with unshrouded rotors, of which it had four. This arrangement simplified the control system, since differential pitch on the rotors gave both pitch and roll control. For yaw control, a small rudder operated in the exhaust of the Turbomeca Artouste IIB shaft drive turbine.
The VZ-7 was essentially consisting a rectangular central airframe to which four vertically-mounted propellers were attached in a square pattern. The central fuselage carried the pilot’s seat, flight controls, fuel and lubricant tanks, and a single 425shp Turbomeca Artouste IIB shaft turbine engine.

Curtiss-Wright’s Santa Barbara Division (formerly the Aerophysics Development Corporation) was awarded an Army contract in 1957 for the development and initial flight testing of two prototype aircraft. Two VZ 7s (58 5508 and 58 5509) were ordered by the Army but only the first was completed and delivered to the Army in mid-1958. It flew successfully during 1959 and 1960 and served its purpose of providing general information on this type of vehicle.
The craft was capable of hovering and forward flight and proved relatively stable and easy to operate but was consistently incapable of meeting the altitude and speed requirements specified by the Army. The VZ-7 was withdrawn from service and returned to the manufacturer in mid-1960.

One of them still exists in storage at the United States Army Aviation Museum collection.

Aero Design & Engineering 840 / 980

In 1980, an increase in turboprop sales led by the Jetprop 980 and Jetprop 840. The former carries up to eight persons and is powered by Garrett TPE-3331-10-501K turboprops. It is characterized by a 309 knot cruise, a 3,176-pound useful load, 5.2 psi pressurization, and enough fuel for a mission-efficient range of 2,040 run with reserves. The 840, powered by twin Garrett TPE-331-5-254K turboprops, boasts speeds up to 290 knots and a maximum range of 1,780 nm with reserves. Rockwell-developed high-technology sound control permits an easy conversation level in the cabins of both aircraft. Standard and custom cabin appointments permit the owner to outfit the interiors with hideaway tables, beverage servers, reclining chairs, telephones, and stereo systems.
The numerical designations of the 840/980 denote maximum potential horsepower per side before derating to a common 700 shaft horsepower each. Both airplanes have Garrett TPE 331s: 10 on the 980 and 5 on the 840. The 980’s greater potential power translates into better climb above 10,000 feet, extra speed and a superior single engine ceiling.
Fuel on the 690B was housed in 22 bladders holding 380 gallons, but the 840/980’s Garretts are fed by a more uniform system. Capacity has gone up to 420 USG, and the wings are wet outboard of the nacelles. Bladders (10 of them) remain in the inboard sections. The new layout cuts refuelling time by two thirds, but at the cost of numerous inspection panels for access to the wet bays. The void left by removal of the fuselage tank on the 840/980 has allowed the baggage volume to be almost doubled to 75 cubic feet.
Absolute ceiling of the 980 is 39,900. The Commander 840 cruises at 267 knots at 31,000 ft. Maximum takeoff weight for the 290B, 840 and 980 is 10,325 pounds, but empty equipped weights for the new ones are down, by 295 pounds on the 840 (6,545 lb) and 255 on the 980 (6,585 lb). Rate of climb has changed little. On both engines, both new airplanes produce 2,840 fpm at sea level; with one dead at 5,000 feet, 900 fpm. Single engine ceiling, however, has risen on the 980 to 26,000 feet compared with 19,600 for the 690B and 20,400 for the 840.

Aero Design & Engineering 695A / 1000

Design changes within the 1000 enabled greater interior space without changing the exterior fuselage dimensions. Cabin length was increased 2.9 feet and the cabin floor lowered nearly four inches to give a cabin height of 4.8 feet. A heavier structure was required all round to take the higher differential and the bottom exterior fuselage skins, replacing the floor of the former pressure vessel, were strengthened. Two aspects highlighted by the changes are the requirement to keep the rails extending the passenger steps clean and the now curved rear pressure bulkhead. The cleanliness of the rails prevents any damage to the seals and resultant loss of cabin pressure. In the 1000 the rear pressure bulkhead is curved, with the rearmost point being almost 3 feet further aft; the additional area accommodating the flushing toilet, small (100 lb maximum) baggage area and refreshment centre.

Aero Design & Engineering Turbo Hawk / 681 Turbo Commander / 690 / Grand Commander / Esquire

690B

The Turbo Commander first appeared in 1965 as a pressurized version of the Grand Commander. Power was supplied by twin 605-shp AiResearch turboprop engines, each driving a three-blade constant-speed reversible-pitch propeller. This model became known as the Turbo Hawk and was built until 1971 when it was replaced by the Turbo Commander 681B, another pressurized version similar to the Shrike Commander, with 717-shp powerplants. The 690 Turbo Commander first flew on 3 March 1969. The North American Rock¬well Turbo Commander 690 was certificated at a gross weight of 10,250lb/4,650kg, in 1972, a payload improvement of 340lb, 155kg. Announcing the increase, the manufacturer stated that the 690, fully equipped, can carry seven people and full fuel tanks giving a range of 1,790 statute miles.

Turbo Commander 681B

In 1964 Aero Commander offered to fit oversize panoramic cabin windows to their Grand Commander at an extra cost of $6000.

The Turbo Commander cabin can be pressurized to 5.2 psi and the operational ceiling is 31,000 feet. Interior temperature is controlled by a high-volume climate system, and heated windshields provide maximum visibility in all weather conditions. The Turbo Commander is also certified for flight into known-icing conditions, and all deicing equipment is standard. While the 690A is just minutes slower that most business jets on a 900- to 1,000-mile business trip, fuel consumption is about 50% less.

The combination of reversible props, tough landing gear, high-wing, and 14-inch prop clearance are custom-tailored for short, rough landing strips. Engines that are flat-rated from 840 shp, to a nominal 700 shp help the 690A climb directly to the best cruise altitude without lengthy step climbing.

Aero Commander 681B N9004N

The 690B was offered in the Executive I and Executive II models. Many features that are usually considered optional are standard equipment in the Executive I, including avionics and cabin accommodations. The Executive II was for owners who wanted to select their own avionics and interior appointments.

After hit¬ting a high of 50 airplanes in 1974, produc¬tion waned, and production was reduced by 1978. Rockwell offered the Shrike in an Esquire version. It was a deluxe model that fea¬tured opulent interiors. The only options in an Esquire II are Rajay turbocharging and air conditioning. Complete deicing, a super plush interior, prop synchro¬nizer, everything from the radar in the nose to the DeVore Tel Tail lighting of the vertical fin is standard equipment. Price, 1978: $329,500.

The aircraft is a kit set, amphibious floatplane constructed from composite materials and powered by a Walter tur¬bine. Aerocomp claim that the aircraft can take off in only 250 feet (in 3-4 sec¬onds) with a full fuel load and five peo¬ple on board, climb at 2,000 ft/min and cruise at 160 knots (TAS). One of the air-craft’s more distinguishing features is its twin vertical stabilisers.
This aircraft can seat 8 adults, with room left over for baggage with inside cabin dimensions of 13 feet x 5 feet (9 feet available aft of the front seats). Powered by the 657 shp Walter M601D turboprop, it cruises between 175 and 200 mph TAS (depending on loading, altitude, power setting, etc).
The Comp Air 10 features modern all-composite construction, and is available in tricycle, tailwheel, or float configuration. Numerous options are available to custom-tailor this airplane to your own specifications.
