Sukhoi Su-27SK Flanker — Primary-Source Flight & Technical Documentation
The Sukhoi Su-27SK is one of the most capable air-superiority fighters ever produced — a cornerstone of Soviet and post-Soviet aviation, engineered for extreme agility, long-range intercept, and sustained air dominance. This collection brings together original factory and military-issue documentation covering the Su-27SK across flight operations, technical exploitation, avionics, and electronic warfare systems.

Technical Profile — Aerodynamic & Systems Overview
The Su-27 utilizes a deeply integrated blended wing-body (BWB) configuration, where the fuselage semi-monocoque structure transitions seamlessly into low-aspect-ratio trapezoidal wings. The entire fuselage generates additional aerodynamic lift, significantly enhancing effective wing area without scaling wingspan. Long Leading-Edge Root Extensions (LERX) generate high-energy vortices at high angles of attack, ensuring continuous airflow attachment and delaying stall behavior.
Powerplant — Lyulka-Saturn AL-31F
- Dry thrust: ~16,700 lbs per engine
- Afterburner thrust: ~27,560 lbs per engine
- Variable-geometry intake ramps with boundary-layer bleeding suppress supersonic shock oscillations
- Retractable titanium FOD mesh screens protect compressor faces during ground operations
Fly-By-Wire & Stability
- SDU-10 quad-channel analog FBW — continuously dampens flight movements, prevents exceedance of structural design envelopes
- Relaxed static stability: aerodynamic center forward of CG under subsonic conditions — inherently unstable by design
- Enables controlled post-stall maneuvers including Pugachev's Cobra (dynamic pitch up to 120°)

⚠️ Regulatory Notice: Under FAA 14 CFR § 43.13 and EASA Part-M, any mechanic performing maintenance on an active aircraft must use current, manufacturer-approved revision-controlled data. This archival document does not satisfy that requirement.
This is an archival, static-copy edition fixed at its original publication date. Intended for historical reference, flight simulation, museum restoration, and educational use only. Not approved for active airworthiness maintenance under FAA 14 CFR § 43.13, EASA Part-M, or equivalent international regulations. Operators of active aircraft must use current, revision-controlled publications from the Type Certificate holder or an authorized distributor.
