Recall from 6-2 that the derivative stability derivative terms zai, and Mi ended up on the lhs as modifications to the normal mass and Inertia terms displaced air is \entrained\and moves with the aircraf rounding These are the apparent mass effects- some of the sur Acceleration derivatives quantify this effect Significant for blimps, less so for aircraft e Main effect: rate of change of the normal velocity w causes a transient

Complementary Filter(CF) Often, there are cases where you have two different measurement sources for estimating one variable and the noise properties of the two measurements are such that one source gives good information only in low frequency region while the other is good only in high frequency region

Goal: analyze aircraft longitudinal dynamics to determine if the be- havior is acceptable, and if not, then modify it using feed back control Note that we could (and will)work with the full dynamics model but for now, let's focus on the short period approximate model from

For general applications in 3D, often need to perform 3 separate rotations to relate our inertial frame to our body frame Especially true for aircraft problems There are many ways to do this set of rotations -with the variations be based on the order of the rotations All would be acceptable

Ron began his career as an aircraft system designer in Douglas Aircraft Company’s Hydro-Mechanical system design group. He became Unit Chief of the braking system design group directly responsible for the design of the DC-9, DC-10, MD-80 anti-skid, auto-brake, brake temperature and tire pressure monitoring

Manager, New Aircraft Development United Airlines I joined United Airlines in 1967 and am presently Manager of New Aircraft Development, a post I have held since 1987. Assignments at United have included Manager of Operational Engineering, Factory Representative at Douglas (our first DC-10 deliveries), Manager of Fuel and Performance Control, Manager of Flight Standards and

Vice President/General Manager Engineering Military Aircraft and Missile Systems Group (retired), The Boeing Company Al Haggerty was vice president and general manager of Engineering for Boeing Military Aircraft and Missile System until March 31st, 2001. He was also the Executive Focal Point for the Lean Enterprise for the unit. Prior to this assignment, he was vice president of Engineering for

Analysis to date has assumed that the atmosphere is calm and fixed -Rarely true since we must contend with gusts and winds -Need to understand how these air motions impact our modeling of the aircraft. Must modify aircraft equations of motion since the aerodynamic forces and moments are functions of the relative motion between the aircraft and the atmosphere, and not of the inertial velocities
