NIFE-AERO ELO's, Questions, & Equations Latest Update 100% Correct LESSON 1 - Basic Theory & Lift Production Lesson 1 DEFINE - Vector Quantity that represents magnitude and direction. Resultant vector may be divided into separate components DEFINE - Air Density Air particles within a given volume. DEFINE - Moment Created when a force is applied at some perpendicular distance from a rotation point STATE - Requirements for an airplane to be in equilibrium flight Sum of all forces and moments is zero about CoG STATE - Requirements for an airplane to be in trimmed flight Sum of all (just) moments is zero - think of a constant turn rate DESCRIBE - Relationship between temperature and altitude Decreases 2 degrees/1,000' up to 36,000' (Lapse Rate). P=pRT DESCRIBE - Relationship between humidity and air density As humidity increases, air density decreases. H2O < O2 STATE - General Gas Law P=pRT DEFINE - Steady Airflow P, p, Temp, V stay constant at each particular point in streamtube EXPLAIN - Continuity Equation A1V1=A2V2 EXPLAIN - Bernoulli's Equation Pt = Ps + Pd, Pd = q = 1/2pV^2 EXPLAIN - Different Types of Airspeeds (I in ICE-TG) IAS - Indicated Airspeed - Instrument airspeed for amount of aircraft dynamic pressure (q). Measured in KIAS. EXPLAIN - Different Types of Airspeeds (C in ICE-TG) CAS - Calibrated Airspeed - IAS corrected for position/instrument error. EXPLAIN - Different Types of Airspeeds (E in ICE-TG) EAS - Equivalent Airspeed - CAS corrected for compressibility error EXPLAIN - Different Types of Airspeeds (T in ICE-TG) TAS - True Airspeed - EAS corrected for density. Actual velocity through volume of air. TAS = sqrt(p0/p)*IAS EXPLAIN - Different Types of Airspeeds (G in ICE-TG) GS - Ground speed - TAS corrected for wind. DEFINE - Mean Camber Line (MCL) Line from the Leading Edge to Trailing Edge that is halfway between upper and lower surfaces of the airfoil DEFINE - Chord The straight line from the Leading Edge to the Trailing Edge. DEFINE - Camber & Camber Types Curvature of the MCL. Max distance between MCL and chord. Symmetric, Positive, Negative DEFINE - Wingspan Wingtip to wingtip distance (b) DEFINE - Wing Area Surface of wing. Wingspan * chord (S) DEFINE - Chordwise Airflow Perpendicular
