How does a zeppelin stay aloft?
It uses lift bags inflated with helium.
What do ships use to maintain balance and stability?
ballast tanks filled with water and stabilizers - fins or wings that can be extended or retracted
How does a satellite differ from a space station? (2 aspects)
A satellite orbits the Earth, while a space station is stationary in orbit.
The man who is credited with designing early ancestors of the airplane based on the flight of birds.
Leonardo da Vinci

8,000 meters
9,000 meters
10,000 meters
8,000 meters

What is the main issue caused by satellite constellations?
Increased radio and light pollution
When was the first aerial refueling successfully demonstrated?
1923
1934
1951
The Airco DH.4 biplane, in 1923, became the first aircraft to successfully demonstrate aerial refueling using a hose and drogue system.
a device that is used to measure or maintain orientation and angular velocity
gyroscope
How is tiltrotor different from helicopter?
tilt rotor aircraft have rotors that can tilt to transition between vertical takeoff and landing like a helicopter, and horizontal flight like an airplane.
Tiltrotor offers advantages in terms of speed, endurance and efficiency
A vehicle that is capable of travelling over both land and water surfaces. It operates by creating a cushion of air between the bottom of the craft and the surface
hovercraft - судно на воздушной подушке
What is the Kessler syndrome?
A potential catastrophic event caused by space debris
What are the Montgolfier brothers famous for?
The Montgolfier brothers are famous for inventing the hot air balloon.
two of the most common ways to measure the depth of the sea
Sound waves from ships and radio waves from satellites
What is the purpose of canards on an aircraft?
Canards are small wings positioned at the front of an aircraft, ahead of the main wings, and they provide additional lift and help control the aircraft's pitch.
How fast is 1 knot?
1,8 km/h
How is the James Webb Space Telescope different from the Hubble Space Telescope?
It is the successor to the Hubble Space Telescope. It is designed to observe the universe in infrared light, enabling observations of distant galaxies and the formation of stars and planets that Hubble cannot detect.
Who developed a full sized, power-driven heavier-than-air machine which made its first flight in 1903?
The Wright brothers! They developed the theory that the air pressure exerted on different parts of the plane could be altered by making the wings adjustable which would maintain equilibrium.
Estimating current position based on previous known position, speed, and direction.
Dead Reckoning
What is Mach 5
Speeds that are faster than Mach 5, which is five times the speed of sound, are hypersonic speeds (6,174 km/h) (1 Mach - 1,225 km/h or 340 m/sec)
Which company is pioneering autonomous long-haul shipping?
Hyundai SpaceX General Motors Rolls-Royce
Hyundai
Rolls-Royce - the first autonomous ship (200)
What is a Lagrange point in space science?
How many are there of those?
Lagrange points are five specific points in space where the gravitational forces of two large bodies, such as Earth and the Moon, balance the centrifugal force felt by a smaller object, allowing it to remain stable relative to the larger bodies.
Five legendary Russian aircraft designers and engineers.
Sideways force generated for horizontal maneuvering of vehicles
