Aircraft Design second flashback

Describe the cabin canopy cabin configuration

Offers exceptional field of view.

Reducing the risk of a mid-air collision.

Excessively high cabin temperature.

Tractor propeller configuration

It provides undisturbed air for the propeller although the higher airspeed.

Pusher propeller configuration

Remove propeller from the field of view.

Allow a high visible cocpit.

What happens if the engine thrust is placed above the CG?

-Occurs nose-down pitch moment.

-Must be trimmed out wing elevator trailing edge up deflection.

What happens if the engine thrust is placed below the CG?

-The higher thrust the greater deflection is required.

-Increase the planform area of the horizontal tail.

Jet engines mounted near the tail

Features the jet engines in pods mounted to the aft of the fuselage.

Engines mounted on pylons under the wings

Vulnerable to foreign object damage.

Reduces airframe weights.

Above wing-mounted engines

It generates nose pitch-down moment at hight thrust.

Intent is to avoid the ground clearance.

Twin turboprop engines mounted in the wing roots

It can lead to serious asymmetric thrust condition.

Nose-mounted tractor propeller engine

Limited thrust effects due to engine placement.

Seaplane

It suffers from substantial pitch effects.

Pusher propeller configuration

Propeller helps keep flow attached on the aft part of the fuselage.

A single turbofan jet engine mounted on the fuselage via a pylon

It would suffer from substantial pitch effects.

Engines buried in the wing

Minimal pitch effects with thrust.

Twin-engine propeller-powered aircraft.

It features a H-tail to help generate restoring yawing moments.

Does having engine placement buried in wings effect the performance of jet engines?

Yes if reduces thrust.

Landing gear config - Tricycle

-Better ground stability and visibility.

Safer against ground looping.

Landing Gear configuration-Taildragger

Less aerodynamic drag

Excellent for bush-plane operations

What is ground looping?

A rapid rotation on a fixed-wing aircraft in the horizontal plane while on the ground.

How to achieve shorter takeoff distance with the taildragger configuration?

High AoA on the ground

Energized lift
