Introduction to Aeronautical Science
2

Aircraft Selection for Analysis

  • Selected aircraft: CRJ100/200, CRJ700/705, CRJ900, CRJ1000, Global 5500
  • All share similar configurations but vary in size
  • Focus on comparing performance metrics and design
Aircraft Selection for Analysis
3

Similarities & Differences of Aircraft

  • Similarities: All are regional jets with similar fuselage designs
  • Differences: Passenger capacity, range, and engine power vary
  • Global 5500 stands out with longer range and luxury features

4

Range vs Takeoff Weight Graph

  • Graph plots maximum range against maximum takeoff weight
  • Trend: Larger aircraft generally have longer ranges
  • Global 5500 shows highest range despite similar configuration
Range vs Takeoff Weight Graph
5

Payload vs Takeoff Weight Graph

  • Graph compares maximum payload weight to takeoff weight
  • Trend: Higher takeoff weight allows for increased payload
  • Similar to range trend, but with more linear progression

6

New Airliner Requirements

  • Airline needs 200-passenger capacity with 3500 nmile range
  • Estimated max takeoff weight based on previous analysis
  • Calculation involves extrapolating from CRJ1000 data

7

Atmospheric Conditions at 22,000 ft

  • Required for multirole jet fighter performance assessment
  • Key parameters: Pressure (P), Temperature (T), Density (ρ)
  • Standard atmosphere models provide these values at altitude

Pressure Calculation Example

  • Airplane velocity: 40 m/s at 2 km altitude
  • Wing airflow velocity: 50 m/s at a specific point
  • Pressure calculation using inviscid, incompressible flow
