Transport drone

A heavy-lift VTOL aircraft that carries up to 30 kg between two fixed points beyond visual line of sight. It flies a planned corridor on its own, lowers or lands a locked payload, and comes home on a safety case you can put in front of a regulator.

The problem

Distance

Two of your sites sit forty minutes apart by road and the thing that has to move between them weighs ten kilograms and cannot wait. A courier is a van, a driver, a shift and a fuel bill for a package that fits in a rucksack, and the road does not care that the sample in the box has a four-hour clock on it. Ferries miss tides, mountain roads close, and a hospital that needs a unit of blood across a city has no good answer between a taxi and a helicopter. What that job needs is a small aircraft that flies the straight line, carries the load in a locked bay, and does it on a schedule a person did not have to drive. Because it flies out of sight of the operator, it has to be trusted to see and avoid, hold its route, and put itself down safely if anything fails. That trust is a safety case, not a promise, and it is the real product here.

Locked 48 L bay or 30 m winch Load cells check mass and CG Cold-chain option, +2 to +8 C

The payload rides in a locked composite bay under the fuselage or on a tension-sensing winch, never on an open hook. Load cells read mass and centre of gravity before the aircraft will arm, so a badly packed or over-mass load is caught on the ground. Without it, a delivery drone is a toy with a strap. With it, a 30 kg case moves sealed and time-stamped, opens only to an authorised code, and can hold a cold chain from +2 to +8 C for blood or vaccines. The same bay and winch fit every airframe in the range.

Fly the route

Out of sight, on a schedule.

Corridor planning, cruise 100 km/h Bonded 4G and 5G, RF fallback ADS-B in and Remote ID

The aircraft flies a planned corridor between two pads on its own, out of sight of the operator, at about 100 km/h. Command and control runs over a bonded cellular link with an independent RF fallback, and it sees crewed traffic on ADS-B while broadcasting Remote ID. Without it, someone drives. With it, the same route is flown every time on a schedule, the operator monitors rather than pilots, and a lost link means a pre-agreed contingency, not a lost aircraft. Range sizes to the load: about 60 km light, closer to 20 km at full mass.

Recovery, designed in.

Ballistic parachute to ASTM F3322 Precision land to +/- 10 cm Independent termination monitor

Recovery is built into the airframe, not bolted on. An independent flight-termination monitor can fire a ballistic parachute built to ASTM F3322 if the aircraft loses control, on its own power, and terminal descent is a measured rate rather than a hope. Without it, a failure over a road is a falling brick. With it, a motor-out or a dead flight computer ends in a controlled descent, and a normal delivery lands on a visual fiducial pad to +/- 10 cm. This is the part that actually gets a route approved.

Payload & bay

Load

The load is the reason the aircraft exists, so it does not hang off a hook and hope. It rides in a sealed bay or on a controlled winch, its weight checked before the motors spin, and its temperature held and logged the whole way.

Under the fuselage

Carried, not hooked

Imagery in production
The bay

Locked, sealed and weighed

The payload rides in a locked composite bay under the fuselage, not strapped to an open hook. The bay takes a case up to 30 x 30 x 40 cm and 30 kg, closes on a mechanical latch with a tamper-evident seal, and only opens to an authorised code or a fiducial at the landing pad. Load cells read the weight and the centre of gravity before the aircraft will arm, so an over-mass or badly packed load is caught on the ground, not in the air. The bay is drained and IP55 sealed, so rain on the pad is not a problem.

Imagery in production
The winch

Lowered where there is no pad

For a courtyard, a ship deck or a field with no clear pad, a controlled winch lowers the load up to 30 m on a tension-sensing tether while the aircraft holds an RTK-fixed hover. The winch reads line tension and cuts to a controlled descent if the load snags, and releases automatically when weight comes off the hook on the ground. Descent is 1 m/s under load, so a box reaches the ground without the aircraft ever leaving a safe height. The hook is a passive carabiner a person on the ground can clear in seconds.

Imagery in production
Cold chain

Held between +2 and +8 C

A powered insert holds the bay between +2 and +8 C for blood, vaccines and tissue, or ambient for spares and documents. The insert runs off the airframe bus, logs bay temperature every ten seconds against the flight clock, and writes it to the delivery record so a cold-chain breach is visible before the box is opened. Phase-change packs hold the set point through a battery swap on the pad. A separate ambient liner carries anything that does not need a temperature at all.

Sealed

From pad to pad

Sealed

A courier is a person you trust with a box. The aircraft is a box you can prove nobody opened. Every leg records who loaded it, what it weighed, what temperature it held and whether the seal was ever broken, and that record travels with the load.

Imagery in production

Tamper-evident seal

The latch takes a numbered seal and the bay only opens to an authorised code at the pad.

Mass and CG check

Load cells confirm weight and balance before the aircraft will arm, so a bad load never launches.

Temperature logged

Bay temperature is written to the delivery record every ten seconds against the flight clock.

Loaded without tools

The case drops in and the latch closes by hand, so a non-technical person on either pad can turn it round.

Routes & BVLOS

Route

Beyond visual line of sight is not a mode you toggle. It is a planned corridor, a link that does not quietly die, and an aircraft that already knows what to do when it hears nothing. That is what turns a demo into a scheduled service.

Under the hood

Beyond line of sight

Imagery in production
Route planning

A corridor, not a joystick

You draw a corridor between two pads on a map and the flight stack turns it into a flyable route: cruise altitude, climb and descent points, and the buffers the safety case requires around people and other airspace. Terrain and obstacle data trim the route to safe clearances, and the plan is checked against a live airspace feed and any temporary restrictions before it will upload. The same corridor is flown every time, so the ground risk is known and repeatable rather than improvised on the day.

Imagery in production
Command link

Two carriers and an RF fallback

Command and control runs over a bonded 4G and 5G link with an independent RF fallback, so losing one carrier does not lose the aircraft. Telemetry, position and bay state come back once a second and the link is AES-256 encrypted end to end. If both paths drop, the aircraft does not wander: it holds, then flies a pre-agreed contingency route to a safe point, all defined before launch and enforced by the flight computer rather than left to a pilot who cannot see it.

Imagery in production
Detect and avoid

Seen, and giving way

The aircraft carries ADS-B in and a Remote ID broadcast to ASTM F3411, so crewed traffic and other drones are seen and the aircraft is visible to anyone watching the airspace. Geofences and no-fly volumes are hard limits in the flight stack, not advisories. Where the safety case calls for it, a ground-based or on-board detect-and-avoid layer adds a right-of-way response, so the aircraft gives way to traffic rather than relying on an operator who is nowhere near it.

One delivery

Mission

  1. Plan the corridor

    Survey the two pads, draw the route, and agree the buffers and contingency points the safety case needs.

  2. Ground and airspace check

    Pre-flight the airframe, confirm mass and centre of gravity from the load cells, and clear the corridor against a live airspace feed before arming.

  3. Launch and cruise

    Vertical launch from the pad, transition to wing-borne cruise at about 100 km/h, flying the corridor with the operator monitoring, not piloting.

  4. Deliver

    Precision land on the fiducial pad or lower on the winch, release the load, confirm the drop, and take on a return payload if there is one.

  5. Return and log

    Fly the return corridor, land, and export the flight, the bay temperature and the delivery record to the file.

Engineering questions

Range and links

How far can it actually fly?

Range trades against payload. At a light 10 kg load the planner sizes to about 60 km one way; at the full 30 kg it is closer to 20 km. It never launches on a leg it cannot finish with a fuel or energy reserve held back.

What happens if it loses signal?

Nothing sudden. On link loss the aircraft holds, then flies a contingency route to a pre-agreed safe point or returns home, all defined before launch. It never continues blindly to the delivery on a lost link.

Can it run more than one route?

Yes. Corridors are saved and reused, so one aircraft can serve several site pairs on a schedule, and a second airframe covers a leg while the first is on charge.

Why it flies

Evidence

Flying a cargo aircraft out of sight of its operator is not a feature you switch on. A regulator lets you do it because you have shown, on paper and in the air, that the ground risk and the air risk are handled: what the aircraft weighs, where it falls if a motor quits, how it avoids other traffic, and how it comes down without hurting anyone. That evidence is a Specific Operations Risk Assessment, and it is the thing that actually gets a route approved. We build the aircraft to close each of those risks with a mechanism you can point to, and we hand you the evidence pack that maps every claim to a test. The airframe is designed around the safety case, not fitted with it afterwards.

Assessed against

Standards

Real frameworks, not a marketing badge.

Recovery

ASTM F3322

The ballistic parachute and its trigger logic are built and tested to ASTM F3322, the standard for small-UAS parachute systems, so the terminal descent rate is a measured figure.

Identity

ASTM F3411

Remote ID broadcasts the aircraft's position and identity to F3411 so it is visible to authorities and other airspace users throughout the flight.

Operations

JARUS SORA

The operation is assessed to the JARUS SORA methodology used by EASA Specific and equivalent frameworks, with each risk mitigated to the robustness the corridor requires.

Engineering questions

Termination and approval

Do you help us get the approval?

Yes. We hand over the airworthiness and recovery test evidence for the airframe, and support your SORA and operational authorisation for the specific corridor and profile you fly.

What triggers the parachute?

An independent flight-termination monitor watches for loss of control and can fire the parachute autonomously or on a manual command. It runs on its own power, so it works even if the main flight computer is dead.

“We could not get the medical route signed off with a hook-and-hope drone. The parachute test data and the SORA pack were what actually moved the regulator.”
