Skyvarta Aerosystems · India

Intelligence and cargo, from above.

We design and build delivery drones, medical payload drones and high-endurance UAVs, engineered from first-principles physics rather than off-the-shelf assumptions.

Platforms

Three drone lines. One engineering discipline.

Every Skyvarta aircraft starts from the mission: what has to be carried, how far, in what conditions. Then we size the rotors, motors, structure and energy system to fit it.

01 / DELIVERY

Delivery Drones

Rugged multirotor aircraft for last-mile logistics, built to lift more than their own weight and to do it repeatedly and safely.

  • High payload-to-weight structures in carbon-fibre composites
  • Quick-release cargo bays and winch-ready payload interfaces
  • Efficient propulsion matched to the payload range
  • Redundant flight-critical systems for dependable operations
FOCUS → PAYLOAD RATIO
02 / MEDICAL

Medical Payload Drones

Aircraft designed around sensitive cargo such as vaccines, blood products and diagnostics, where time, temperature and handling decide the outcome.

  • Insulated, temperature-aware payload compartments
  • Payload-condition monitoring and telemetry to the ground
  • Smooth, low-vibration flight profiles to protect contents
  • Built for reaching remote and hard-to-access locations
FOCUS → PAYLOAD INTEGRITY
03 / ENDURANCE

High-Endurance Drones

Long-loiter and long-range aircraft for inspection, mapping, monitoring and surveillance, where every watt-hour has to count.

  • Large, lightly loaded rotors for low hover power
  • Weight-optimised airframes and energy-dense power systems
  • Long-range command, control and data links
  • Payload-ready for imaging and sensing missions
FOCUS → MINUTES PER WATT-HOUR
The physics

Great drones are decided on the whiteboard.

Lift, power, endurance and signal range all follow from a handful of physical laws. We design to them from the first sketch.

01 · Momentum theory

Why bigger rotors hover longer

Pideal = T3/2 / √(2ρA)

To hold weight, a rotor must accelerate air downward. Spreading the same thrust over a larger disk area A moves more air more slowly, which cuts the power needed. This is why efficient endurance aircraft carry large, lightly loaded propellers.

02 · Rotor efficiency

Figure of merit

FM = Pideal / Pactual

Real propellers lose energy to drag, tip effects and swirl. Blade shape, tip speed and motor matching decide how close we get to the ideal. Higher figure of merit means more minutes in the air for the same battery.

03 · Energy budget

Endurance

t = η · Ebatt / Phover

Flight time is usable battery energy divided by power draw. Extra battery adds weight, which needs more thrust and more power, so returns diminish fast. Good endurance comes from balancing the whole system.

04 · Lift capability

Payload ratio

PR = mpayload / maircraft

A high ratio demands high thrust-to-weight, torque-dense motors and a structure that is both stiff and light. Our 2:1 result at the DARPA Lift Challenge came from optimising all of these together.

05 · Communications

Link budget

Pr = Pt Gt Gr (λ / 4πR)²

Signal strength falls with the square of distance. Antenna gain, frequency and placement on the airframe decide how far and how reliably a drone stays connected, which is why antenna design is core to long-range work.

06 · Thermal control

Protecting sensitive cargo

Q = U · A · ΔT

Heat leaking into a payload bay scales with its surface area, insulation quality and the temperature difference to the outside. Medical payloads are designed so the cargo stays in range for the full mission, including delays.

Technology

The full stack behind every aircraft.

From the propeller to the antenna, we engineer each subsystem and, more importantly, how they work together.

01

Propulsion

Motor, propeller and speed-controller matching for the target thrust, efficiency and thermal limits.

02

Airframe & structures

Lightweight, stiff composite structures designed for high payload fractions and field-repairable durability.

03

Power systems

Battery sizing, power distribution and monitoring built around mission energy budgets and safety margins.

04

Antenna systems

Antenna selection and placement for robust control, telemetry and video links over long ranges.

05

Radar & sensing

Radar and sensor expertise supporting situational awareness and obstacle detection for safer operations.

06

Avionics & autonomy

Flight control, navigation and mission planning for repeatable autonomous flights with sensible failsafes.

Leadership

Built by engineers who fly what they design.
