Aviation
This control surface on the trailing edge of a wing primarily changes lift by altering wing camber.
What are flaps
These objects orbit the Sun and often develop bright tails when near it.
What are comets
What number was the last Apollo mission?
What is Apollo 17?
This narrow-body aircraft from Boeing is the best-selling commercial jetliner in history.
What is the Boeing 737
This principle states that an increase in fluid velocity results in a decrease in pressure
What is Bernoulli’s principle
The standard atmospheric pressure at sea level used for altimeter calibration is this value.
What is 29.92 in of mercury
This reusable rocket developed by SpaceX became famous for landing its first stage vertically after launch.
This rocket launched the first human mission to the Moon.
What is the Saturn V
This high-speed reconnaissance aircraft, capable of Mach 3+, was developed by Lockheed’s Skunk Works.
What is the Lockheed SR-71 Blackbird
This type of engine compresses incoming air using rotating compressor blades and powers most modern jetliners
What is a turbofan engine
The pressure altitude corrected for nonstandard temperature is called this.
What is the Density Altitude
The speed required to completely escape Earth’s gravity without further propulsion is called this.
What is escape velocity
The first aircraft to break the sound barrier was piloted by this test pilot in 1947
Who is Chuck Yeager
This experimental rocket-powered aircraft became the first to exceed Mach 6 during hypersonic flight testing
What is the X-15
This atmospheric layer contains most weather and extends roughly up to 10–12 km above Earth
What is the Troposphere
This aviation acronym helps pilots remember the steps to recover from a stall
what is PARE?
P - power: idle
A - ailerons: neutral
R - rudder: full opposite deflection
E - Elevator: Forward
The farthest and closest points in the moons orbit around the earth are called this.
What are Perigee (closest) and Apogee (farthest)
This Cold War–era reconnaissance aircraft could cruise above 70,000 feet to avoid interception
What is the U-2
This variable-sweep wing fighter served extensively in the U.S. Navy during the Cold War.
What is the F-14 Tomcat
This spacecraft designed by Burt Rutan became the first privately funded vehicle to carry a human into space twice within two weeks.
What is SpaceShipOne
This aerodynamic phenomenon occurs near Mach 1 when shock waves form and drag increases rapidly.
What is wave drag or the transonic drag rise
This maneuver uses two engine burns to transfer a spacecraft between circular orbits.
What is the Hohmann Transfer
This German aviation pioneer made over 2,000 successful glider flights in the late 1800s and carefully documented lift measurements from curved wings, greatly influencing later aircraft designers.
Who is Otto Lilienthal
This experimental aircraft used forward-swept wings to improve maneuverability but required advanced composites to prevent structural divergence.
What is the Grumman X-29
In aircraft stability analysis, this point along the chord is where pitching moment does not change with angle of attack
What is the aerodynamic center
