2007 Saab 210 Draken (drakonas arba aitvaras) yra sumažintas dvigubos delta koncepcijos bandymas kuriant J 35 naikintuvą. Nors "Saab" niekada oficialiai neįvardijo nieko, išskyrus "Draken", netrukus jis tapo žinomas neoficialiu slapyvardžiu "Lilldraken" (mažasis drakonas arba mažasis aitvaras) po pirmojo "Saab 35" prototipo skrydžio. Pirmasis jo skrydis buvo 1952 m. sausio 21 d.

General Characteristics and Role

The SAAB 210 Lilldraken (“Little Dragon”) was a revolutionary Swedish experimental aircraft designed and built by Saab in the early 1950s. It was created purely as a one-third scale research platform to test the novel and complex double delta wing configuration proposed for the supersonic Saab 35 Draken fighter. The Lilldraken was a critical step in the Draken’s development, as the double delta design—characterized by a small, highly-swept inner delta wing and a larger, less-swept outer delta—was entirely new and its aerodynamic properties needed real-world validation, especially at low speeds. Its unique profile and small size made it one of the most distinctive and important experimental aircraft of its era.

Design Innovations and Performance

  • Engine: 1 x Armstrong Siddeley Adder turbojet engine (non-afterburning).
  • Thrust: Approx. 475 kgf (1,047 lbf).
  • Key Innovation: The primary purpose was to test the double delta wing, which was necessary to give the subsequent Draken fighter both high-speed performance (via the inner delta) and low-speed stability (via the outer delta).
  • Air Intakes: The Lilldraken featured large lateral air intakes on either side of the cockpit, which were also representative of the intended design for the larger Draken.
  • Test Program: The aircraft successfully performed numerous flights, validating the stability, control, and general handling characteristics of the radical double delta configuration before the full-scale fighter was finalized.

Legacy and Final Status

  • Successor: The knowledge gained from the Lilldraken program was directly applied to the full-scale development and successful deployment of the Mach 2-capable Saab 35 Draken fighter.
  • Operational Status: Only one example of the SAAB 210 was ever built.
  • Preservation: The single prototype is now preserved and displayed at the Flygvapenmuseum (Swedish Air Force Museum) in Linköping, Sweden.
