Aircraft Performance

Comprehensive Aircraft Performance Analysis

At the heart of every aerospace design is a single, unifying goal: performance. At Fabexco, we bring together aerodynamic, propulsion, and mass properties data to deliver integrated, physics-based performance analyses that quantify what your aircraft can do – and how well it will do it.

From mission effectiveness to certification readiness, we provide detailed insights into every phase of flight, tailored to your vehicle’s configuration, design maturity, and operational context.

Our capabilities include:

• High-Speed and Low-Speed Regime Analysis:
  • Takeoff, climb, cruise, descent, and landing assessments
  • Transonic, supersonic, and hypersonic performance modeling
  • VTOL, STOL, and hover evaluations for rotorcraft and eVTOL concepts
• Mission-Specific Performance Modeling:
  • Combat radius, ferry range, time-on-station, and payload-range tradeoffs
  • Fuel efficiency and endurance analysis across variable mission profiles
• Time-Integrated Performance Metrics:
  • Full-profile simulations accounting for energy state, fuel burn, and dynamic mass changes
  • Reserve fuel modeling and loiter/abort scenarios
  • Time-to-climb, acceleration, and turn rate estimations
• Standards-Based Analysis:
  • Conformance with FAR 23, FAR 25, and relevant military performance requirements
  • Failure-mode assessments including one-engine inoperative (OEI), degraded thrust, or asymmetric configurations
• Preliminary Performance Estimates:
  • Parametric sweeps of performance vs. altitude, payload, environmental conditions, and system degradations
  • Identification of performance-critical mission segments and design margin thresholds

Applicable across a wide range of platforms:

• Fixed-Wing Aircraft: Commercial, general aviation, and special mission
• Combat Aircraft and UAVs: Strike, loiter, high-speed dash, and ISR
• Rotorcraft & eVTOL/UAM Platforms: Vertical lift, transition, and energy budget optimization
• Reentry & Skip-Glide Vehicles: Glide ratio, thermal limits, and trajectory shaping for atmospheric entry

Typical deliverables include:

• Performance Databases:
  • Tabulated data for climb rate, cruise speed, glide ratio, turn rate, and descent metrics
  • Sensitivity charts for payload, altitude, and environmental effects
  • Off-design performance conditions, including OEI and degraded-mode operations
• Mission Profile Simulations:
  • Visualizations of time-integrated trajectories
  • Analysis of multi-segment missions, from takeoff to landing, with fuel, consumable resources, and time-tracking metrics.
• Documentation:
  • Methodology and assumptions
  • Trade-off evaluations and performance optimization recommendations
  • Supporting graphics for stakeholder communication or design reviews

Whether you’re building a next-gen air mobility platform, validating a supersonic vehicle, or refining a long-endurance UAV, Fabexco delivers the actionable performance data you need – early enough to guide the design, and deep enough to support success.
