Petra vs Valkyrie

JYRO Petra · Performance Designs Valkyrie · 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

Petra is made by JYRO; Valkyrie is made by Performance Designs.
Planform: both are listed as elliptical.
Both have 7 cells.
Both are cross-braced.
Petra is listed in 55–89 sq ft; Valkyrie in 67–111 sq ft.
The listed size ranges overlap between 67 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)	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) ↗	HIGHLY experienced cross-braced canopy pilots Expert canopy pilots Getting back from long spots Camera flyers Terminal and Sub-terminal deployments Individuals looking for a high performance canopy for competition Individuals who have mastered their current cross-braced canopy and are looking for the next step in performance Source: Performance Designs — Valkyrie product page ↗
Characteristics (manufacturer keywords)	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) ↗	NOT intended as a first cross-braced canopy · Highly responsive to all inputs · Powerful rear riser performance · Great stopping power/shut down · Smooth openings Source: Performance Designs — Valkyrie product page ↗
Opening	Firm but not hard; brisk when terminal (JYRO).	Openings smooth, well-staged and with less tendency to search for a heading during inflation.
Recovery arc	Long recovery — requires pilot input for level flight (JYRO).	not published
Glide	High maximal glide ratio (JYRO).	Very efficient in converting speed into lift; even better than a Comp Velocity at getting you back from long spots.
Speed / dive	Very long, steep dive; 'the most high performance wing you can buy' (JYRO) — no airspeed figures published.	Higher speeds in a dive (qualitative; no figures published).
Flare	Very powerful and responsive (JYRO).	Highly responsive to toggle input and has a powerful flare; stopping power is impressive.
Front risers	Very light (JYRO).	Front riser pressure slightly higher than a Comp Velocity, but it wants to rotate, and rotate fast; potential for faster and more powerful turns.
Rear risers	Range, range and more range; very responsive (JYRO).	More power and a wider range on rears than on the Comp Velocity.
Harness response	Highly sensitive (JYRO).	Much more sensitive to harness input than a Comp Velocity; rolls into turns almost effortlessly.
Toggle response	Highly sensitive; high-speed stalls possible with abrupt inputs (JYRO).	Highly responsive to toggle input.
Loading system	Recommended wing-loading range 2.5–3.0+ lb/ft² plus a chart with jump-number bands (below).	Maximum exit weight per PD skill category and size (chart below).
Manufacturer-stated experience requirements	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)	none stated
Evidence level	B — Manufacturer product information	A — Manufacturer technical documentation

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.
