Bombardier CRJ900: 515 mph Regional Jet & The Backbone of Short-Haul Aviation
The Bombardier CRJ900 is not merely a regional jet—it is the workhorse of short-haul aviation, connecting smaller cities to major hubs across North America, Europe, and Asia. With a cruise speed of 515 mph (Mach 0.78), seating for up to 90 passengers, and exceptional fuel efficiency, the CRJ900 has become the backbone of regional airline fleets. Part of the Canadair Regional Jet family, the CRJ900 represents the pinnacle of regional jet engineering. This is the engineering story of Bombardier's most successful regional aircraft.
1. Overview: The Regional Jet Leader

3. Powertrain & Propulsion System
Engine Configuration — GE CF34-8C5 Turbofans
The CRJ900 is powered by two General Electric CF34-8C5 turbofan engines, mounted on the aft fuselage—a design that reduces cabin noise and allows for a clean wing.
- Engine Type: High-bypass turbofan (5.0:1 bypass ratio)
- Thrust: 13,790 lbf (61.3 kN) each
- Specific Fuel Consumption: 0.38 lb/lbf-hr
- Fan Diameter: 48 inches (1.22 meters)
- Number of Stages: 1 fan, 14 compressor, 2 turbine
- Manufacturer: General Electric Aviation
- Noise Certification: Stage 4 (Chapter 4) compliant
Aft-Engine Configuration
The CRJ900's aft-mounted engine design offers several advantages over wing-mounted engines.
- Cabin Noise: Quieter cabin compared to wing-mounted engines
- Wing Design: Clean wing without engine pylons improves aerodynamic efficiency
- Ground Clearance: Lower fuselage allows for shorter landing gear
- Maintenance Access: Easy access to engines from ground level
- Weight Distribution: Aft weight helps balance the aircraft
"The CF34-8C5 engine is one of the most reliable turbofans in regional aviation," said a GE Aviation engineer. "It delivers exceptional fuel efficiency and durability, with an on-wing reliability rate of 99.98%." [Source: GE Aviation]
4. Aerodynamics & Velocity Engineering
The CRJ900's aerodynamic design is optimized for efficiency and high-speed cruise.
- Wing Design: Swept wing with 25-degree sweep for transonic efficiency
- Winglets: Optional blended winglets for 2-3% fuel savings
- Fuselage: Narrow-body (8.2 ft / 2.5 m diameter) for reduced drag
- T-tail: Horizontal stabilizer mounted at top of vertical fin
- Advanced Airfoils: Supercritical wing sections for improved performance
- Drag Coefficient: Estimated 0.025 (very efficient for its class)
Insight: The CRJ900's swept wing and T-tail design allow it to cruise at Mach 0.78—comparable to larger narrow-body jets like the Boeing 737 and Airbus A320. This speed allows regional airlines to offer competitive flight times on routes up to 1,500 nautical miles.
5. Comparison: CRJ900 vs Regional Jet Competitors
To understand the CRJ900's position, it must be compared to its primary competitors: the Embraer E175 and the Airbus A220-100.
\d \d €Context: The CRJ900 was the fastest and most capable regional jet when introduced. While newer aircraft like the A220 offer better fuel efficiency and range, the CRJ900 remains a cost-effective workhorse for regional airlines, with hundreds still in service.
6. Technical Breakdown: The CRJ Family
The CRJ900 is part of the larger Canadair Regional Jet family, which includes several variants.

7. Engineering Insight: The T-Tail Advantage
The CRJ900's distinctive T-tail design is a key engineering feature that sets it apart from wing-mounted engine aircraft.
Why this matters: The T-tail places the horizontal stabilizer at the top of the vertical fin, out of the wake of the wings and engines. This provides several advantages:
- Clean Wing: No engine pylons or flaps interference
- Better Pitch Control: The tail operates in undisturbed airflow, providing more consistent elevator authority
- Shorter Fuselage: Allows for a more compact fuselage design
- Improved Short-Field Performance: Better pitch authority during takeoff and landing
The T-tail design does have one drawback: it is more susceptible to deep stalls, requiring careful aerodynamic design and stall protection systems. Bombardier addressed this with a stick pusher system that automatically lowers the nose if the angle of attack becomes too high.
"The T-tail is a signature of the CRJ family," said a Bombardier aerodynamicist. "It allows us to achieve the performance and efficiency that regional airlines need, while maintaining the safety margins required for commercial aviation." [Source: Bombardier Engineering]
8. Why It Matters
The Bombardier CRJ900 matters for three reasons. First, it revolutionized regional aviation, bringing jet speed and comfort to routes previously served by turboprops. Second, it established Bombardier as a global leader in regional aircraft, competing directly with Embraer. Third, it remains a critical part of the global airline fleet, with hundreds of CRJ900s still in service with airlines like Delta Connection, American Eagle, and SkyWest.
With its 515 mph cruise speed, 90-passenger capacity, and exceptional reliability, the CRJ900 connected smaller cities to the world. It allowed travelers to bypass major hubs, flying directly from regional airports to destinations across North America and Europe.
