Tu-134 CAD Project
A Short-Haul Jetliner Shaped by the Soviet Design Philosophy
See Product Packs Technical Page for Bundle of All Variants
The Tupolev Tu-134 was one of the most recognizable short- to medium-range jet airliners of the Cold War era. Developed in the early 1960s, it embodied the Soviet approach to civil aviation:
- robust construction
- high-field performance
- adaptability to varied infrastructure conditions across the USSR and Eastern Bloc nations.
With its rear-mounted engines, distinctive glazed nose on early variants, and long operational life, the Tu-134 became a cornerstone of Aeroflot’s domestic network and a familiar sight across Eastern Europe, Asia, and beyond. This repository preserves the Tu-134 family in CAD form, documenting its evolution from early prototypes to later production variants, reconstructed with engineering-grade accuracy.
Aircraft Family Overview
The Tu-134 was not a single fixed configuration, but a family of closely related variants developed to address changing operational, navigational, and regulatory requirements:
- Tu-134 Prototype – Early development aircraft defining the basic configuration
- Tu-134 (Early Production) – Initial service variant with navigator’s glazed nose
- Tu-134A – Improved performance, revised engines, and higher payload capacity
- Tu-134B – Final major production standard with modernized cockpit and systems
Each variant is documented as a separate subpage, allowing direct comparison of structural, aerodynamic, and systems-level evolution.
Available Variants Right Now:
- Tu-124A (Tu-134 Prototype) – Development aircraft bridging Tu-124 and Tu-134 concepts
- Tu-134A-5 (Early Production) – Initial service configuration with full navigator glazing
- Tu-134A-2 (Modified) – Late navigator variant with compromised blister and refined nose
- Tu-134B-3 (Final) – Final production standard with redesigned nose and reduced crew
- Tu-134M (Proposal) – Post-Soviet stretched and modernized concept with PS-90 engines
- Tu-134UBL (Military) – Specialized RuAF / VVS / VKS training and operational variant
Design Philosophy
The Tu-134 reflects several core Soviet design priorities:
- Operation from short and semi-prepared runways
- Rear-mounted engines to reduce runway debris ingestion
- Simple, durable structural solutions
- High dispatch reliability across extreme climates
- Compatibility with existing ground infrastructure
Unlike many Western contemporaries, early Tu-134 variants retained a navigator station in the nose, emphasizing independent navigation capability for less-developed airspace environments.
CAD Reconstruction Approach
All Tu-134 models in this project are built as engineering-grade CAD geometry, not visualization meshes.
- Fully lofted NURBS surfaces
- Solid fuselage, wing, nacelle, and tail geometry
- Parametric structure for dimensional consistency
- Variant-specific geometry preserved (nose, engines, wings, systems)
- Cross-sections exportable for DXF / DWG
The focus is on geometric fidelity and configuration accuracy, suitable for study, comparison, and fabrication workflows.

Defining the Configuration
Main Article: Tu-124A / Tu-134
The Tu-134 prototype represents the earliest realization of the design, establishing the aircraft’s distinctive layout and aerodynamic baseline.
Key Characteristics
- Early fuselage proportions and cockpit layout
- Initial wing geometry and incidence
- Prototype-specific engine integration
- Development-focused systems and instrumentation
- Absence of later performance refinements
CAD Notes
This model captures the aircraft in its formative state, before production optimizations. Subtle differences in wing root integration, fuselage contouring, and engine placement highlight the design decisions evaluated during early testing. The prototype variant is essential for understanding how the Tu-134’s configuration matured into a long-lived production aircraft.
Tu-134 (Early Production)
The Original Service Aircraft
The early production Tu-134 introduced the aircraft into widespread service, retaining several features rooted in earlier navigation and operational practices.
Design Features
- Glazed navigator’s nose, housing a dedicated crew station
- Production-standard fuselage length
- Early engine variants with characteristic acoustic profile
- Conventional tailplane and control layout
- Structural robustness tailored to regional operations
- Operational Context
This variant served extensively with Aeroflot and export customers, operating on domestic and international short-haul routes. Its configuration reflects a transitional era between classic multi-crew navigation and emerging automated avionics.
CAD Fidelity
- Accurate nose glazing geometry
- Production-standard fuselage lofts
- Correct engine nacelle shaping for early variants
- Fully solid, parametric geometry
Tu-134A
Performance and Payload Refinement
The Tu-134A marked a significant improvement over earlier variants, addressing payload limitations and operational efficiency.
Engineering Improvements
- More powerful and efficient engines
- Increased maximum takeoff weight
- Revised wing and systems integration
- Improved climb and hot-and-high performance
- Retention of navigator station on most aircraft
- Significance
The Tu-134A became one of the most widely produced and operated variants, balancing performance improvements with continuity in crew procedures and maintenance practices.
CAD Reconstruction Focus
- Updated engine nacelles and pylons
- Structural changes supporting higher loads
- Aerodynamic refinements captured in wing and fuselage geometry
- Variant-accurate external configuration
- This model highlights how incremental engineering changes extended the Tu-134’s operational relevance.
Tu-134B
The Final Production Standard
The Tu-134B represents the final and most refined production variant of the aircraft.
Key Changes
- Removal of the glazed navigator’s nose
- Revised cockpit layout with reduced crew requirements
- Cleaner, more aerodynamically efficient nose profile
- Updated avionics and systems
- Improved operational efficiency and maintainability
Design Maturity
By this stage, the Tu-134 had fully transitioned into a modernized short-haul jet, aligning more closely with international practices while retaining its characteristic Soviet robustness.
CAD Precision
- Redesigned nose geometry accurately modeled
- Final-production fuselage configuration
- Mature wing and tail integration
- Fully parametric, solid-body construction
The Tu-134B illustrates the aircraft at peak maturity—technically refined, operationally efficient, and visually distinct from its predecessors.
Why the Tu-134 Matters
The Tu-134 occupies a significant place in aviation history:
- One of the most recognizable Soviet jet airliners
- Operated for decades across diverse environments
- Demonstrated a distinct alternative to Western short-haul design philosophy
- Bridged early jet transport concepts and later standardized cockpit practices
- Preserving the Tu-134 family in CAD form allows these design decisions to be examined beyond photographs and anecdotal history.
