Comp Velocity vs Petra

Performance Designs Comp Velocity · JYRO Petra · Canopy explorer

Manufacturer facts side by side, with the source on every row. Nothing on this page says which canopy to choose or what wing loading to fly — that is a conversation for you, your canopy coach and your drop zone.

What differs — read from the data

Comp Velocity is made by Performance Designs; Petra is made by JYRO.
Planform: both are listed as elliptical.
Both have 7 cells.
Both are cross-braced.
Comp Velocity is listed in 71–111 sq ft; Petra in 55–89 sq ft.
The listed size ranges overlap between 71 and 89 sq ft.
The manufacturers publish different systems: Performance Designs lists a maximum exit weight per skill category and size; JYRO lists a recommended wing-loading range and a chart with jump-number bands. They are shown side by side, never translated into each other.

Structural facts only (manufacturer, planform, cells, bracing, sizes, chart system). How each wing flies is described below in the manufacturer's own words; how it flies for you is a question for a canopy coach.

Designed for (manufacturer wording)	Highly experienced canopy pilots First-time crossbraced canopy pilots Getting back from long spots Camera flyers Individuals learning high performance canopy piloting under appropriate supervision Individuals looking for a high performance canopy for competition Source: Performance Designs — Comp Velocity product page ↗	Experienced competitive canopy pilots with thousands of jumps on small, highly loaded crossbraced canopies (competition-specific) Source: JYRO — Petra product page (page modified 2026-09-15) ↗
Characteristics (manufacturer keywords)	Great openings · Long recovery arc · Very steep glide · Great shut down power · Responsive and powerful canopy Source: Performance Designs — Comp Velocity product page ↗	Firm but not hard openings · Highly sensitive toggles and harness · Very long, steep dive · Long recovery requiring pilot input for level flight · High-speed stalls possible with abrupt inputs Source: JYRO — Petra product page (page modified 2026-09-15) ↗
Opening	Quite similar to the Velocity, with a bit more refinement; the amount this canopy "searches" or "shakes" during the snivel stages is quite reduced.	Firm but not hard; brisk when terminal (JYRO).
Recovery arc	Long recovery arc (product page); recovery from a front riser dive longer than with a Velocity.	Long recovery — requires pilot input for level flight (JYRO).
Glide	Very steep glide (product page).	High maximal glide ratio (JYRO).
Speed / dive	Flies a bit faster and is, in general, a more efficient wing than the Velocity (qualitative; no figures published).	Very long, steep dive; 'the most high performance wing you can buy' (JYRO) — no airspeed figures published.
Flare	Great shut down power (product page); toggle stroke may be longer and stall point lower; slow speed efficiency exceeds the Velocity.	Very powerful and responsive (JYRO).
Front risers	Front riser dive characteristics very similar to the Velocity; pressure about the same, but builds a bit differently.	Very light (JYRO).
Rear risers	Most pilots state that it feels more powerful on the rears; flies more efficiently on the rears.	Range, range and more range; very responsive (JYRO).
Harness response	not published	Highly sensitive (JYRO).
Toggle response	Comes standard with three additional inches of brake to toggle line compared to a Velocity; toggle stroke may be longer and stall point lower.	Highly sensitive; high-speed stalls possible with abrupt inputs (JYRO).
Loading system	Maximum exit weight per PD skill category and size (chart below).	Recommended wing-loading range 2.5–3.0+ lb/ft² plus a chart with jump-number bands (below).
Manufacturer-stated experience requirements	none stated	700+ jumps at WL 2.2 or above 250+ jumps in the last 12 months Reference from a respected coach/swooper or Petra/Peregrine pilot Competed at least once in the last 12 months (or 3+ Open competitions in the last 3 years)
Evidence level	A — Manufacturer technical documentation	B — Manufacturer product information

Flight wording is quoted or closely paraphrased from each manufacturer's own documents; where a manufacturer publishes nothing for a row it says "not published". No airspeed figures are published by either manufacturer.

Your wing loading on each size

Exit weight (you + all gear): kg

Enter an exit weight to see exit weight ÷ size for every listed size of both canopies and where each number sits on the manufacturer's own chart.

Wing loading = exit weight (lb) ÷ size (ft²). PD's chart lists the MAXIMUM exit weight per skill category — the category shown is the lowest one whose maximum covers your weight, by PD's own rule. JYRO's range is a manufacturer envelope, not a target. The two systems are never translated into each other.
