unit 2 test AERO

failure point

condition caused by collapse, break, or bending. structure can’t fulfill its purpose.

cross-sectional area

surface or shape exposed by cutting straight in right angles to the axis. used to find area of 3d objects

feedback

return of input from prior output. used in auto-correction or for changes in machines, systems, processes

flange

broad ridge or a pair of ridges at a right angle to strengthen and stiffen a structure

flaps

located in the midpoint of each wing. increases lifting efficiency and decreases stall speed

FMS

flight mangement system. uses preprogrammed databases for air routes

fuselage

houses the cabin, cockpit, and common attachment to other parts of plane

GA

civil aviation that doesn’t have an air schedule.

galaxy

assembly of stars, matter, gas. held by gracity

horizontal stabalizer

structure located at the tail of the plane. keeps fuselage aligned in pitch. it’s horizontal but the forces it creates are vertical

generator

device that mechanical energy → electrical energt

geostationary earth orbits

GEO. orbits where a satellite stays in one spot with respect to earth

glider

aircraft without engine

GPS

global positioning system. highly accurate position and velocity information and precise time

high hypersonic

aircraft speed at Mach 10-25

wing span

dist. of wingtip to wingtip

hypersonic

mach 5-10

compression

material made with multiple layers bounded by a matrix

IFR

instrument flight rules. rules that make intstrument flight

ILS

instrument landing system. physical visual aids to land and electronic instruments; localizer, glideslope, outer marker, middle marker, and approach lights.

indicated speed

speed shown on the aircraft indicator

inclination

angle between Earth’s equatorial plane and plane of orbit

input

information fed by data processing

INS

inertial navigation system. RNAV system that is self-contained navigation.

intake stroke

when the piston moves away from piston head

kell effect

flat surfaces behind the center of gravity tend to weathervane with the wind(points to where the wind is going)

kessler syndrome

prediction of future collisions in orbit

knots

measure of speed in aircrafts and boats in nautical mile

L/MF

low or medium frequency. 190-535 kHz is low, above 300 kHz is medium

LAAS

local area augmentation system. focuses on airport area

lapse rate

rate at which temp decreases when increasing altitude

lateral axis

horizontal line perpendicular to plane’s airpath.

latitude

place from the equator form the two poles. IIIIII

leading edge

part of airfoil that meets airflow first
