## Abstract

The present invention relates to a flying car capable of vertical takeoff and landing on the ground/water, wherein the flying car includes: a body having a predetermined volume; a wing provided outside the body; and a propulsion module connected to the body and provided to generate propulsive force for flying, wherein the propulsion module is provided to be operated on the basis of drone-type control.

## Claims

### Claim 1

A flying car capable of vertical takeoff and landing on ground/water, the flying car comprising:
a body having a preset volume;
a wing provided outside the body;
a propulsion module connected to the body and provided to form a propulsive force for flight;
a buoyancy boat connected to a lower portion of the body and configured to provide a buoyant force by which the flying car floats on the water; and
a flight assistance module accommodated in a space formed inward at a rear end of the buoyancy boat and configured to be withdrawn rearward,
wherein the propulsion module is provided to be operated based on drone-type control,
wherein the flight assistance module is configured to be withdrawn rearward from the buoyancy boat when the flying car is in a landed state, and
wherein the flight assistance module is configured to be covered by a tent member when the flight assistance module is in a withdrawn state.

### Claim 2 (depends on 1)

The flying car of claim 1, wherein the wing has a variable length.
