Identify by airplane characteristics

This experimental fighter has a similar appearance as the Saab 29 Tunnan, so with an air intake in the nose and exhaust below the rear fuselage. It was used to test variable sweep wings.

This tiltrotor was a research aircraft for what would later become the V-22 Osprey. The XV-15 has large diameter rotors at the wingtips, that act as propellers when the whole nacelles are tilted forward. All gears are retractable have double wheels. Finally, the vertical fins have a significant sweep.

The Osprey tiltrotor aircraft has large diameter rotors at the wingtips, that act as propellers when the whole nacelles are tilted forward. All retractable gears have double wheels. The rear fuselage slopes up to allow (un)loading via a rear ramp. The vertical fins have non-swept trailing edges.

This Bellanca aircraft has a square fuselage cross section, with flat panel windows. It is powered by a radial piston engine. Typical are the two wings struts on each side, with their long chord, at least the lower three quarts.

The Beriev A40 Albatross amphibian aircraft has an unusual configuration with jet engines on top of and behind the high wings. It has a long nose, stabilising floats near the wing tips, a bullet fairing on top of the vertical stabiliser and a main landing gear with four wheels. (photo: Mike Freer/WikiMedia)

After the failure of the Beriev A40 the company made a smaller version, designated Be-200. It has a short nose, engines with separate fan exhaust, no bullet fairing at the top of the tail and two wheel main landing gears.

This turboprop commuter aircraft has cockpit windows like the L-410 and rectangular cabin windows. Like on many Antonovs the wings have a slight anhedral. The single wheel main gears are retracted rearward in the long nacelles.

Unlike many similar amphibian aircraft the Be-6/Be-12 has a tail gear, of which the main gear retracts in the side of the fuselage. Typical are the gull wings, H-tail with significant dihedral on the horizontal stabilisers and glass nose.  

Like many of its contempories the Blériot XI has a largely open frame fuselage with square cross section. The wings are curved, flat surfaces without ailerons or other flaps. They are braced by wires. The aircraft has no vertical fin, just a large rudder at the end of the fuselage.

The main characteristics of this twin vertical tail, twin engine fighter are the cropped delta shaped wings, wedge shaped air intakes at the side of the fuselage and bubble canopy. Distinctive compared to similar aircraft are the tops of the vertical stabilisers, with a sort of antennas pointing forward.
