Overview

Designed for Tethered Flight

Conventional high-pressure hoses are reinforced with steel wire or bulky textile braid[cite: 3]. They are too heavy for drone flight — suspended hose weight quickly consumes the payload budget[cite: 3]. SkyHose 10 uses high-tensile aramid fibre, giving a full 190 bar working pressure at a fraction of the weight, and stainless steel quick-connects for rapid deployment.

01

Feed

Ground pump connects via male quick-connect. Stainless steel construction ensures pure-water compatibility.

02

Fly

Ultra-light aramid braid and polyurethane sheath minimise suspended load as the drone ascends.[cite: 3]

03

Wash

Female quick-connect locks directly into the drone spray lance. 190 bar delivered at the nozzle.

Advantages

Why Aramid Makes Sense on a Drone

Lightweight

At 102 g/m bare, a 50 m line adds under 5.2 kg of dry mass — preserving flight time and payload headroom.

High Pressure

190 bar (2,750 psi) continuous working pressure handles tough façade deposits and long vertical runs.

Safety Factor

760 bar (11,020 psi) burst pressure gives a 4:1 safety ratio, compliant with industrial pressure standards.

Stainless Fittings

Pre-crimped stainless steel couplings at both ends. No corrosion, no rust staining on clean glass or stone.

Kink Resistant

Aramid structure resists collapsing or kinking under dynamic flight movements and ground-reel payout.[cite: 3]

Pre-Assembled

Arrives crimped, tested, and ready to fly. No field assembly or specialist crimping tools required.[cite: 3]

Field Guidelines

Operating Notes & Care

Bend Radius

Never bend tighter than 125 mm (5 in). Reel drum diameter must be at least 250 mm (9.9 in) to avoid permanent core damage.

Coupling Direction

Water enters via the male quick-connect on the ground reel and exits through the female quick-connect at the drone lance.

Pre-Flight Purge

Flush and bleed all air from the line before takeoff. A water-filled line behaves predictably; air pockets create surge forces.[cite: 3]

Inspection

Check the outer sheath for cuts, kinks, or abrasion before each operation. Replace any hose with visible braid damage.[cite: 3]

Payload Calculation for SORA & Flight Planning

Total suspended load governs available flight time and aircraft selection. Calculate as follows:

Suspended Load (kg) = Altitude (m) × 0.173 kg/m + Lance Mass (kg)

Example: 50 m altitude with 1.0 kg lance = (50 × 0.173) + 1.0 = 9.65 kg total payload. Ensure this is within the aircraft’s maximum payload rating at operating altitude and temperature.

FAQ

Frequently Asked Questions

How much weight does the drone lift with the SkyHose 10?
Hose and water together come to 173 g per metre suspended — 102 g of hose and 71 g of water. At 30 m that is 5.2 kg (11 lb), at 50 m 8.7 kg (19 lb), at 100 m 17.3 kg (38 lb). These figures assume the full length hanging vertically and completely filled, which is the worst case; the catenary and reel support normally keep the airborne share lower. Add the lance and any drone-mounted hardware on top when sizing payload.
Which diameter should I choose?
Larger bore means lower pressure loss over a long run, but more lifted mass. Start from the flow your ground system delivers and your aircraft’s payload capacity, then take the smallest bore that carries that flow. The three diameters share the same construction, the same fittings and the same safety factor.
What is the working pressure?
The hose is rated 190 bar (2,750 psi) working with a 760 bar (11,020 psi) burst pressure — a 4:1 safety factor. The quick-connects are rated 300 bar (4,350 psi), so the hose is the limiting component and the assembly rating is 190 bar (2,750 psi).
Why aramid rather than textile braid?
Aramid carries a higher load per unit of mass, so a single braid reaches the same pressure class at a lower weight per metre than an equivalent textile-braided construction. On a hose the aircraft has to lift for its full working height, that difference goes straight into flight time and reachable altitude.
Which end connects to the ground system?
The male quick-connect is the inlet and connects to the ground system; the female quick-connect is the outlet and receives the lance. Water always enters through a male fitting and leaves through a female one, the same way a power socket works. The convention is fixed across the WasherDrone range.
Can two hoses be joined together?
Yes. With a male fitting at one end and a female at the other, two lengths connect directly. Each additional joint adds pressure loss, a potential leak point, and mass in the air, so plan the run rather than extending it in the field.
What lengths are available?
30 m (98 ft) / 50 m (164 ft) / 100 m (328 ft). All three carry the same hose, the same fittings and the same pressure rating.
What is the minimum bend radius?
125 mm (5 in). Reel drums should be at least 250 mm (9.9 in) in diameter. Coiling tighter than this damages the reinforcement permanently and is not covered by wear.
Is the wet path suitable for purified water?
The couplings and unions are stainless steel throughout the wet path, so the assembly does not introduce metals into water fed from a reverse-osmosis stage.
Is the ground pump or the lance included?
No. The SkyHose is a supply line. The ground system and the drone-mounted lance are separate products.
