About Online Aviation Library

Online Aviation Library is a data publisher — not a regulatory authority, government institution, or official distributor. Our mission is to collect, structure, preserve, and publish surviving original aviation documentation. We operate on three principles: Preservation before reconstruction. Authenticity before completeness. Original evidence before modern interpretation. We don't teach; we tell stories.

The Bréguet Br.1050 Alizé (French for "Tradewind") was a French carrier-based anti-submarine warfare (ASW) and maritime patrol aircraft developed by Breguet Aviation in the 1950s. Highly reliable and characteristically portly to house its bulky electronics, it served as a primary workhorse for the French Navy (Aéronavale) and the Indian Navy for over four decades.

The Tsybin NM-1 was a full-scale, subsonic Soviet aerodynamic The Tsybin NM-1 was a full-scale, subsonic Soviet aerodynamic prototype built in 1957 to test the low-speed handling, take-off, and landing characteristics of the proposed Tsybin RSR Mach 3 strategic reconnaissance aircraft. Developed by Pavel Tsybin's OKB-256 design bureau, the NM-1 (which stood for Naturnaya Model or "life-size model") successfully completed its first flight on April 7, 1959. While the NM-1 proved the viability of the radical aerodynamic layout, the wider high-altitude spy plane project was ultimately cancelled by Soviet Premier Nikita Khrushchev in 1961.
Program Outcome
Though the NM-1 demonstrated handling qualities that were actually superior to active frontline jets like the MiG-19 and Su-7 during testing, the program was overtaken by geopolitical shifts. As the Soviet Union pivoted heavily toward ballistic missiles and early spy satellites, strategic reconnaissance aircraft were deemed redundant. Work on the operational variants was halted just as the pre-series airframes were being assembled. Pavel Tsybin was later transferred to Sergei Korolev's design bureau, where his aerodynamic expertise directly influenced the development of the Zenit reconnaissance satellites.

The Nord 1500 Griffon was a revolutionary French experimental interceptor aircraft developed in the mid-1950s by state-owned manufacturer Nord Aviation. It was built to test a cutting-edge, dual-propulsion concept that combined a conventional turbojet with a massive, integrated ramjet to achieve high supersonic speeds.
Propulsion System
The Griffon utilized a unique combined-cycle powerplant layout:
SNECMA Atar 101E-3 Turbojet: Located inside the core of the fuselage, this conventional jet engine produced 34.3 kN (7,700 lbf) of thrust. Because ramjets cannot generate thrust at a standstill, the turbojet was used for unassisted takeoffs and initial acceleration.
Nord Stato-Réacteur Ramjet: The surrounding hollow fuselage acted as a giant ramjet duct, producing 67.8 kN (15,200 lbf) of thrust. Once the aircraft exceeded speeds of around 1,000 km/h (600 mph), the ramjet was ignited to provide massive acceleration at high speeds

"Human beings are driven by illusion, hope, and opportunity — chained together with the skill of people, materials, government money, the urgency of war, and the incredible engineers, pilots, and entrepreneurs who came along to make one idea work."
