Schweizer RU-38B Twin Condor

 

 

 

 

The Schweizer RU-38 Twin Condor is a two or three-seat, fixed gear, low wing, twin boom covert reconnaissance aircraft.

 

RU-38 is the US military designation for the aircraft, indicating Utility, Reconnaissance. The Schweizer company model number is Schweizer SA 2-38A Condor and, in its three-seat configuration, Schweizer SA 3-38A Condor.

 

Based on the Schweizer SGM 2-37 motor glider, a total of five RU-38s have been produced between 1995 and 2005. The aircraft remains in production.

Si,hai pienamente ragione;ho sbagliato ha tradurre la Wiki in inglese....Non sapevo che Alenia avesse partecipato avesse fatto degli studi su quel tipo di motori

LTV Electrosystems (in seguito E-Systems) L-450F

In the late 1960s, following the early microwave HALE vehicle studies, the US Air Force worked with LTV Electrosystems (later E-Systems) under the Compass Dwell program to build an endurance UAVs using much more conventional turboprop propulsion. At least part of the motivation or inspiration for this effort was derived from the Igloo White program, which was a multiservice attempt to cut the flow of supplies from North Vietnam to South Vietnam through the network of paths and roads running through Cambodia and Laos known as the "Ho Chi Minh Trail".

 

Igloo White involved seeding the region with thousands of seismic and acoustic sensors, most of them air-dropped, which would pick up indications of traffic along the trail and report them back to a central command center in Thailand, which would dispatch air strikes in response. The sensors were battery-operated and had limited range, so airborne radio relay aircraft orbited above the battle area to pick up the signals and pass them on to the command center.

 

Originally, the radio relays were EC-121 Warning Star aircraft, a military variant of the Lockheed Super Constellation four-piston engined airliner, but these machines were expensive to operate. They were replaced by Beech Debonaire single-engine light aircraft, modified for the radio relay role and given the military designation of "QU-22A". They could be operated as drones, but apparently nobody trusted that as operational practice, and they were never flown unpiloted except on an experimental basis.

 

LTV Electrosystems' development effort focused on an endurance aircraft that could be flown as a piloted aircraft or a UAV. A number of prototypes, including piloted and UAV versions, were built and flown. They were based on a Schweizer sailplane design with major modifications by Schweizer to accommodate a Pratt & Whitney Canada PT6A-34 turboprop engine, large fuel tanks, and operational payloads. The aircraft had fixed tricycle landing gear.

 

The first prototype, designated the "L-450F", was piloted. It first flew in February 1970, but was lost in an accident on its third flight in March 1970, the pilot bailing out safely. A second L-450F was built and used to complete the flight test program. The third prototype, the first UAV variant, was designated the "XQM-93" and flew in early 1972. It had no cockpit or other provisions for piloted flight. It could carry a payload of 320 kilograms (700 pounds). The Air Force ordered four XQM-93s but it is unclear that all were actually delivered, since Compass Dwell was cancelled that year.

 

Secondo alcune fonti (inclusa wiki) almeno la versione non pilotata sarebbe stata usata nel SE Asiatico, ed uno dei due prototipi, con matricola civile, stabilì alcuni record di quota per la sua categoria.

 

Sembra un po' "A YO-3A, on steroids and only one pilot"

Berliner Helicoplane

 

 

 

 

1921 single-wing, rotary-powered helicopter with deflector vanes at the wingtips.

 

 

 

 

 

Berliner Trihelo

 

 

 

 

 

 

Early experiments with helicopters began with Berliner's first machines, a 1907 single-blade model with his own design 36hp rotary (built by Adams Co, Dubuque IA) driving a 17' rotor at 150rpm, and a 55hp Adams-Farwell twin-blade version with rotors on either side of cockpit. (It was noted in 1909 Jane's that a parachute was carried "for emergencies.") Although both had marginal flight characteristics, they were historic events as the first time a rotary engine flew (but it took the French to popularize them). In 1913, a basic framework design based on the Williams Helicopter, dubbed "gyrocopter," did gain brief, tethered flight, but those who credit this as the world's first man-carrying helicopter overlook Cornu and Bréguet's flights in France many years earlier. Berliner's first helicopter recognizable as such—a wheeled platform with two rotors above the pilot's seat—made its first flight a few feet high on 6/10/20 (p: son Henry Berliner), and managed to travel forward for a measurable distance. Continuing experiments produced the first helicopter to achieve controlled horizontal flight—a war-surplus Nieuport biplane fighter with tilting tail rotor, and a short-span upper wing with 14'0" helicopter blades at the tips. In a demonstration for the military, on 7/16/22, at College Park MD, it rose to 12' and made a few short-distance flights (p: Henry Berliner). On 2/23/23, a triplane version (220hp Bentley rotary; span: 38'0" length: 20'6" rotors: 15'0") flew at an altitude of 15' for a little more than a minute and a half.

BELL 65 ATV, 1954 VTOL "Air Test Vehicle." Two 1000# Fairchild J44 turbojets, tiltable 90° for lift and propulsion + one Turbomèca Palouste turbo-generator delivering compressed air to the attitude control system; span: 26'0" length: 21'0" v: 125/x/0. Built from wings from a Cessna 170, fuselage from a Schweizer glider, and landing gear from a Bell 47. Hovering and conventional flights were made on 11/16/54 and 12/18/58 respectively (p: David Howe), but no transitions. The test program was terminated in 1955. POP: 2 [N1105V, x], with the second one destroyed in an engine fire on the ground.

Decazes Helicoplane

 

 

Around 1902, Viscount Decazes and G. Besancon had conducted tests of a 6m diameter vertically mounted propeller in Paris for a planned concept that would have used two of these vertical thrusting propellers, in addition to fixed wings and a propeller for forward thrust. The "rotor" tested produced 67kg of lift at 60 rpm, requiring 10hp. Without a flight weight engine, however, Decazes would have to weight ten more years to build his idea. In 1912, Decazes built his prototype "Helicoplane" at the Loire et Olivier Aircraft plant, and it was tested the following year by Commandant Dorand at Villacoublay. It used two 50hp Gnome rotary engines, one for the co-axial four-bladed rotors and one for the propeller. Two wings in tandem had approximately 25m2 surface area each. Although it was not intended to hover without a head wind, it was planned to have minimum speed of 18km/h. A transmission failure, however, ended the tests prematurely, prior to flight.
